Creating a backup copy and restoring data. Database backup and recovery. Backup solutions from acronis

Backup It is only effective when it is performed regularly. If data changes frequently, copying should also be frequent. Therefore, many people prefer to use special software to automate this process rather than copying data manually.

Any computer is at risk of failure hardware and many other dangers that may lead to the loss of important data. In the business sector, this has especially dire consequences, since the loss of business data leads to huge losses and loss of customers.

The key to backup tools is data recovery. Really, what's the use? backup copy, if you can't restore it? Therefore, when choosing a backup program, you need to make sure that you can easily restore the desired data with it.

Backup program for Windows

Handy Backup is a reliable data backup and recovery program for computers running Windows, known for its simple and user-friendly interface and a huge number of functions. To create a copy or restore data, you simply need to create a new "task" (using step-by-step Wizard creating tasks). Handy Backup helps you back up the following data:

Files and folders

Handy Backup can restore both the entire backup and individual files and folders.

Popular utilities and applications

The program can perform automatic search and backup of many popular applications, including Outlook, Skype, Adobe Photoshop and etc.

Disk image

Handy Backup can create an exact copy of the HDD, including the operating system, boot records and other information. You can copy and restore both the entire hard drive and its individual sections.

You can create a special bootable recovery disk using the Handy Backup Disaster Recovery utility, from which you can start the operating system in the event of a failure, and restore the system, settings and all data.

Supports all versions of Windows systems

The program provides the ability to work in various Windows versions, including, you can backup and restore Windows 8.

Database

The program can copy ODBC compatible databases, and also has special plugins for exact copying of DB2, Oracle, MS SQL, MySQL, etc. databases.

MS Exchange and mail data

The application is capable of backing up and restoring MS Exchange Server data without stopping the server. And also create an automatic backup of mail from Yandex.Mail, Mail, Gmail, Yahoo Mail, etc. servers.

Data backup is an important function for every responsible computer user. There is nothing worse than realizing while sitting in front of your computer that you have just lost the result of a month’s work or important files that there is no way to recover.

Data very often comes at a high price. And it doesn’t matter whether these are personal files or information that is used for work. Let's figure out what functions for data backup and recovery Microsoft developers have equipped the latest version of their operating system– Windows 10, and also consider the possibility of backing up data recovery using third party programs.

Data backup: What is it?

File backup

We sometimes hear about the need to “back up your computer.” But it’s not entirely correct to say this, since there are two ways to backup data. The first is creating a backup copy of files, with which you can create copies of individual files and folders stored on a computer or any other storage medium. Every user who has important data stored on their computer should create a backup copy of it on an external hard drive, in case the original source is lost or deleted.

System backup

Another method of backing up data is known as System Backup or System Image. This is a more complex method of backing up data, since in this case we are talking about creating a copy of the entire operating system of a particular computer, along with programs, files and settings. A system backup is used to restore it if Windows becomes unstable or stops working altogether.

A Windows backup can take up hundreds of gigabytes of memory. But using special data backup software, you can configure the function to save only changes that have been made since the last system backup.

Backing up and restoring data using Windows

Windows 10 has built-in tools that are designed to create backup copies of files and the system, as well as restore information using them. Many users do not use them, not knowing about their existence or how to configure them correctly. They are more likely to use third-party programs rather than tools built into the operating system.

File history

The most in a simple way creating a backup copy of files and folders, as well as restoring from them, is File History. Using this function, you can copy data regularly, according to a schedule set by the user, and save it on external hard disk or other external storage medium. You can also save copies of files to your computer's hard drive (although this goes against the basic rule of backup).

To set up File History, go to the Start menu and select Settings. In the Settings menu that opens, go to the Update and Security / Backup menu.

On the right side of the panel, in the File History Backup section, click Add Disk. You will be asked to select one of the external storage media connected to your computer. Select the one to which you want to back up data and set the archiving parameters: the interval for saving copies of files and the duration of their storage; if necessary, you can specify a specific folder for a copy of files from which you want to create or remove unnecessary ones.

When creating a backup, File History also automatically copies all folders account user: Images, Documents, Downloads, etc.

This feature can be turned off at any time, but in order for user-specified data to be copied at a set time interval, Automatic file backup must be enabled.

By default, files are backed up every hour. The minimum time that can be set is 10 minutes, the maximum is Daily. You can also set the duration of storage of copies: from one month until free space is needed (in this case, older backups will be deleted automatically to free up space for new backups).

Restoring files from a backup

To restore files from a backup disk, go to Control Panel and select the File History menu.

In the left column of the window that opens, select Recover personal files, go to the folder and find the file that needs to be restored. To restore a file, click the green button below and specify the path to restore it. Versions of backup files based on the dates and times they were saved can be selected by pressing the right and left arrow buttons.

Cloud service OneDrive

Another way to protect yourself from losing important files is to transfer them to cloud storage and synchronize it with your computer. There are many such storages: Dropbox, Google Drive, etc. But a feature of the latest versions of Windows (10, 8, 8.1) is the presence of Microsoft’s own cloud service built into the operating system, called OneDrive.

When using one of the cloud services, they usually create a folder on the computer disk under their name, from which they synchronize files. IN latest versions Windows folder OneDrive exists by default, i.e. the service is available to every user immediately after installing the operating system.

Any file. which will be saved in this folder will be immediately copied to the cloud storage and synchronized with it. The user can also access the files in this folder from any other device; to do this, just log into your OneDrive account from it.

Recovery Point

Another side of backup and recovery Windows data 10, there is recovery system files and operating system performance. Creating and restoring a backup copy of the operating system is a more complex process than with the user's personal files and folders. But for this purpose, Windows 10 provides special function- System Restore. With its help, the user can restore the functionality of the operating system by “rolling back” to the saved earlier state – the Restore Point.

By default, the recovery function in the operating system is not activated. In order to be able to use it, it must be configured. System Restore works by creating Restore Points, which save the state of Windows at a specific point in time. Along with the settings and state of the operating system, the Recovery Point includes installed applications(For example, Microsoft Office) and device drivers (for example, video cards).

The user can create a recovery point at any convenient time. It is also created automatically if you install an application on your computer or download system updates, etc. But remember that System Restore does not restore the user's personal files.

If you begin to notice that the operating system is not working correctly or with glitches and errors, then you can run one of the previously saved restore points and Windows will return to the state at the time it was created.

To do this, go to the Control Panel and select the menu Recovery / Set up system recovery / Configure, with which you activate and configure the function.

To restore Windows from a restore point, go to Control Panel and select the menu Recovery / Run System Restore, select the required Restore Point and click Next.

System image

Probably the most basic and complex Windows backup feature is a feature called System Image.

Using this option, you can create a “duplicate” of the entire computer disk, including Windows 10, as well as all programs and personal data of the user. The system image is saved to an external hard drive, from which, if necessary or the computer fails, it is deployed back to the computer’s hard drive. As a result, the user receives a working version of the operating system, along with programs and files.

This is a very useful function, but its disadvantage is that the user does not have the ability to restore individual files from the system image, as from File History. You can only fully expand the entire image. Therefore, users often use these functions in parallel.

To create a System Image, go to Control Panel and select the File Backup and Restore menu. In the left column, click Create a system image, and select the drive to which you want to save it. Please note that the System Image is usually large in size.

To restore the system from a System Image, go to the System Settings / Update and Security / Recovery menu, and select special boot options. After Windows 10 reboots, select System image recovery from the menu provided.

Backup and Restore

The fundamental challenge for any data center is to ensure a service level agreement between IT and the business. The key point in meeting business requirements is guaranteeing data safety, therefore an integral infrastructure block of the data storage subsystem of any properly organized data center is a data backup and recovery system.

The SNIA (Storage Networking Industry Association) defines backup operations as follows:

Backup copy - data stored on non-volatile media, usually remotely, intended for recovery if the original copy of the data is lost or inaccessible.
Backup is the process of creating backup copies.

All data backup systems can be divided into three types according to the copy method used: it can be file-by-file copying, block copying or application-level data copying.

The block backup system (English image-level or block-level backup) works directly with the media, ignoring file structure, and saving all the contents completely - the operating system, work data, settings, etc. The advantage of performing this type of backup is its high speed. However, usually when performing copy operations, you need to pause applications so that the copy is consistent.

When performing backup operations at the file level (eng. file-level or file-based backup), use file system. In this case, a relatively simple task is to restore some specific files. In general, backup operations take longer, additional loading of the operating system occurs, and there is also a problem with accessing open files.

Backups can also be performed at the application level (application-level backup). Copy and restore operations are carried out using a specially provided in the backup application software interface API (Application Programming Interface). A backup is a collection of files and possibly other objects defined by the application itself, which together represent the state of the application at some point in time. At this method backup, there may be a compatibility problem between different versions of applications and backup systems that implement the corresponding interface.

The backup system is a service subsystem of the data center and has the following features:

The backup process is not critical for solving IS problems, i.e. A failure in the backup system does not reduce the availability of critical information services.
The load on computing resources that the backup process creates is not useful from the point of view of providing IS information services.

When building a backup system, you must:

Reduce backup data traffic on the shared corporate computer network.

Backup methods.

LAN backup
Before the advent of Storage Area Networks (SANs), to reduce backup traffic on the core network, a dedicated backup network was used, as well as a tiered structure that included multiple copy servers. Dedicating a copy server and locating it on the network “closer” to the productive servers that process the largest volumes of information allows you to localize backup traffic between the copy server and productive servers and reduce the load on the shared LAN.

LAN-free backup
With the advent of SAN, it became possible to transfer backup traffic not through a LAN, but directly from servers to storage devices (usually tape libraries) connected to the SAN. This method is called "LAN-free backup". When using this method, the server-client, simultaneously with other tasks, performs the functions of a server for copying backed up data to storage devices available to it via SAN. In this case, the backup management server is entrusted with the task of executing the backup schedule by issuing control actions via the LAN (via the TCP/IP protocol) and monitoring the execution of tasks by the copy servers. Thus, the problem of reducing backup data traffic on the LAN is solved.

But the "LAN-free backup" method does not solve the backup window problem. Moreover, this method creates additional load on client servers, assigning to them additional functions of copy servers for backup data. Some applications allow you to perform online backups, this is implemented in many transactional applications and through special backup software options such as copy tools open files. However, the use of such technologies does not reduce the load on productive servers, which, with large volumes of data (terabytes or more), can increase the time for solving basic problems beyond the acceptable threshold.

Serverless backup
The ideal backup scheme would be one in which the server-client data is copied via a SAN to a storage device by some third-party device (called a “Data Mover”), without using the computing resources of the client server and without interrupting its operation. This backup method is called "Serverless backup". The role of "Data Mover" can be performed either by a server dedicated for this purpose, connected to the same disk array as the productive server, or by a special device - a router.

CDP (Continuous Data Protector)
As defined by SNIA, Continuous Data Protection (CDP) is a technique for continuously tracking data changes and storing them in storage independent of the original data, allowing recovery to any point in time in the past. CDP systems can be implemented at the block, file, or application level and provide fine-grained recovery of objects at any point in time, down to a single write operation. According to this definition, all CDP solutions have the following properties:

Changes are constantly monitored and recorded
All changes are stored on a separate logical device
RPO (recovery point) is arbitrary and should not be determined in advance.

Examples of implementations.

In this article, we will look at data backup techniques for small and medium-sized businesses.

A typical question that customers ask is: ensuring the safety of the 1C system database, about 1 GB in size, and the client database in MS Access, about 300 MB in size. All information is important and losing more than a day of work is not advisable. The budget allocated to the IT department does not exceed 100,000 rubles.

It is necessary to understand the customer's requirements - how much information needs to be backed up, how long backup copies need to be stored, whether remote storage (offline) of backup copies is required.

If the customer needs to store data for the next few days and the cost of the solution should be minimal, then the simplest and most convenient solution would be a small network data storage (NAS - Network Attached Storage). These devices are produced by various equipment manufacturers, have from 2 to 12 disks and provide access via the main access protocols: CIFS, NFS, HTTP, iSCSI. The block diagram of the solution is shown in Figure 1.

Fig.1 NAS storage.

The cost of this solution ranges from 15,000 to 70,000 rubles, depending on storage volumes.

The main disadvantages of this solution are the inability to scale as storage volumes grow and the need to monitor the success of backups.

To automate backup procedures, use special software, which controls the backup process and recovery procedure, and also allows you to work with various storage media, including tape devices.

To create backups, backup policies are created that regulate “What, Where and When.” What data should be saved, where and with what frequency. Additional features of centralized backup software allow you to restore individual messages and database tables without the need to restore the entire volume of data. Recording backup copies on tape allows you to organize remote storage of backup copies and safety of important data in the event of a disaster. Using tape media to store archival copies allows data to be read 50 years after it was recorded.

The cost of such a solution starts from 50,000 rubles and includes a server for storing backup copies and backup software.

6.3. Backup and restore data using Handy Backup software

The likelihood of successfully recovering data after its sudden loss is much higher if the user has foreseen the possibility of such a nuisance in advance and has taken care to keep his data in a safe place by creating a backup copy. In this section, we will get acquainted with a program that is designed and created specifically to create backup copies of data and restore them if necessary. Moreover, with its help you can recover not only individual files and folders, but also the entire contents of your hard drive. The relevance and usefulness of the latest functionality can hardly be overestimated, given the fact that the vast majority of users store a lot of necessary and important information on their hard drive.

This program is called Handy Backup, its developer is the Novosoft company (program website - www.handybackup.ru). The program is shareware: its demo version can be downloaded from the developer’s website. A distribution kit of about 12.5 MB is offered for download.

It is worth noting that the demo version has a time limit: it can be used for 30 days from the date of installation, after which you need to either register the program or remove it from your computer.

To install Handy Backup on your computer, you need to run the installation file and then follow the instructions of the installation program. Upon completion of installation in the menu Start a program group will be created Handy Backup, the commands of which are intended to launch the program, call up help information, go to the program’s website, and also uninstall it. For ease of use, it is recommended to display the launch shortcut on the desktop.

The program has a clear and visual user interface, as well as convenient tools. It is also important for domestic users that Handy Backup supports the Russian language.

6.3.1. Functionality Handy Backup

The Handy Backup program is a multifunctional product designed to backup and restore data, as well as to synchronize it, and these processes can be performed automatically at certain intervals - you just need to make the appropriate settings. The program successfully copes with the assigned tasks both on a separate computer and when working on a local network.

Handy Backup allows you to create backup copies of any user-specified objects. One of its most important and most popular functions is the creation of a hard drive image, which implies a backup of the operating system, applications, drivers used, as well as the user’s personal data.

The program's capabilities include hard drive cloning. For those who do not know what this is, let us explain: cloning a hard drive is a sector-by-sector copy of it, which allows you to quickly restore the operating system if the need arises.

The program can backup databases (including from SQL tables, MS Access, Oracle, PostgreSQL, FoxPro, etc.), save email, Lotus Notes data, and also create backup copies of the Windows registry.

The created backup copies can be packaged in a zip format to save space, and the archive can be password protected to prevent unauthorized and unqualified access to the stored data.

Of particular note is the ability to backup data using an FTP connection, which not all competing products can boast of.

6.3.2. Structure user interface

After starting the program, its user interface is displayed on the screen, which is shown in Fig. 6.28.

Rice. 6.28. Handy Backup user interface

The key elements of the program's user interface are: main menu, toolbar, context menu, task area, file area, log window and status bar. Let's briefly look at each of the listed elements.

The main menu of the program is located in the usual place - at the top of the interface. It includes the following items: File, View, Actions, Service, Language And Help. Each item contains a list of commands intended to select the required operating mode or call the corresponding program function.

Immediately below the main menu there is a toolbar. Its buttons do not carry any additional functional load, and only duplicate some commands of the main menu. The toolbar button names appear as tooltips when you move the mouse pointer over them. Note that even in the localized version of the program these tips are displayed on English language, but in any case this does not make it difficult to use the buttons: firstly, they have a characteristic design, and secondly, even the English-language hint makes it easy to determine what a particular button is for.

Note. If necessary, you can remove the toolbar from the interface. Its display is controlled using the main menu command View? Toolbar .

The program's context menu is called up by clicking the right mouse button, and its commands also duplicate some of the main menu commands. Content context menu may be determined by the current operating mode and the location in which it is called.

Below the toolbar is the task area. It displays a list of current tasks. For each task, the following information is displayed sequentially in the corresponding columns.

Task name (assigned by the user at the task setting stage).

Task type ( possible options – Backup, Recovery or Synchronization).

The last time this task was executed.

The time of the next launch of this task in accordance with the established schedule (if a schedule was configured for it when the task was created).

Task completion indicator;

The current status of the task.

Note that each task can take one of the statuses listed below.

Expectation– this status assigned to tasks awaiting execution commands.

Backup, Recovery or Synchronization– one of these statuses (depending on the type of task) is assigned to tasks that are in the process of execution.

Success– status means that the task was successfully completed.

Scheduled– this status is assigned to tasks that are awaiting execution in accordance with a previously established schedule.

Error– this status is assigned to tasks during which errors occurred for some reason.

Below the task pane is the files pane, which is used to manage the data involved in tasks. In other words, the user has the ability to manage files and folders as if they were tasks.

For each object, the following information is shown in the corresponding columns.

File or folder name.

The current status of the object.

Initial object size (note that for folders this information not shown).

The size of the saved object.

The time the file or folder was last edited.

The time the file or folder was last saved.

You can customize the set of information shown for objects in the files pane. To do this, right-click and select the required items in the context menu that opens. The only information that cannot be disabled is the object name (the corresponding command in the context menu will be blocked).

Below the task area there is a log window. It displays the contents of an automatically generated log file that provides information about the progress of the task. Note that this information is updated automatically as the task progresses. By right-clicking anywhere in the log window, a context menu appears on the screen, using the commands of which you can copy the contents of the log window to the clipboard, save it in a separate file, completely clear the log screen, and also switch to the font color settings mode and messages.

If necessary, you can remove the log window from the interface. Its display is controlled using the main menu command View? Log window? Hide/Show log window.

At the bottom of the interface, under the log window, there is a status bar that displays information about the current operating mode. The display of the status bar is controlled using the main menu command View? Status bar.

6.3.3. Handy Backup Settings

As with many other applications, before you start using Handy Backup, it is recommended to review and, if necessary, change the program settings in order to best adapt it to the specifics of use on a given computer. To switch to this mode, use the main menu command File? Settings, also called by pressing a key combination Alt+F7. When this command is activated, a window is displayed on the screen, which is shown in Fig. 6.29.

Rice. 6.29. Program settings, section basic settings

The structure of this window is as follows: on the left side there is a list of sections, and on the right side the contents of the current section are displayed. Each section includes the same type of settings, similar in functionality and purpose. Let's take a closer look at some of them.

In chapter basic settings(see Fig. 6.29) there are several general parameters. If the checkbox is checked Launch agent when Windows startup , then the program will be placed in the automatic download directory and will be launched along with the operating system.

You can add the Handy Backup item to the operating system context menu - to do this, go to the section basic settings check the box Allow integration with Windows Explorer.

During program operation (in particular, when compressing and encrypting objects), temporary files are created, which are stored in a temporary directory. The path to this directory is indicated in the area Temporary folder. You can use the temporary folder of the operating system for this purpose - to do this, check the box Use Windows temporary directory.

If in the section basic settings If the checkbox is selected, then when copying is complete, the CD drive will automatically open to eject the disc. Sometimes it is useful to check the results of copying to disk: to do this, check the box Eject CD/DVD after backup. When this checkbox is checked, one more parameter becomes available - Stop checking after the first error. If it is installed, then when the first error is detected, the disk scan will be stopped. The meaning of this parameter is that sometimes even one error is enough for the recording to be considered unsuccessful.

In chapter Logging you can define the maximum allowed log file size. To do this you need to check the box Log file size limit, and in the field on the right, enter the maximum permissible value in kilobytes using the keyboard. In the same section you can configure the color scheme of the log window.

In chapter Data transfer connection parameters are configured. The contents of this section are shown in Fig. 6.30.

Rice. 6.30. Program settings, section Data transfer

In field Maximum network latency You should specify how long the program should wait to receive a response from the network. This parameter is expressed in seconds; by default it is assigned the value 120 . If after the specified time the connection has not occurred, then after a pause the program will attempt to reconnect. The duration of this pause is indicated in the field Delay between reconnections, and the number of connection attempts is in the field. If the checkbox is checked Repeat until successful completion, then the field Retry attempts for network errors becomes unavailable for editing. In this case, the program will make connection attempts until one of them is successful. The program can inform you about the progress of its processes by email. This is a very convenient functionality: it will allow you to control the position even if you do not have direct access to this computer (it is enough to have access to an electronic mailbox from any other place). The necessary settings are made in the section Notifications by E-mail, the contents of which are shown in Fig. 6.31.

Rice. 6.31. Program settings, section Notifications by E-mail

First you need to check the box Use email notification - only after this the parameters will become available for editing Email. In field SMTP Server the address of the SMTP server for outgoing mail messages is indicated, and in the field Port– SMTP server port number (in most cases you need to enter a value here 25 , and it is this that the program suggests using by default).

If the SMTP server you use to send email messages requires authorization, check the box Use SMTP authentication, then enter your username and password in the fields below.

You can check the correctness of the settings using the button Send test message. Please note that this requires a working internet connection.

All completed program settings take effect after clicking the button in this window OK. Using a button Cancel exits this mode without saving the changes made. Please note that in most cases, the default program settings are optimal.

6.3.4. Disk Image Backup

As we noted earlier, one of the program’s functions is to backup a hard disk image. By having a disk image, you can later easily recover your data even if your hard drive becomes damaged.

It is worth noting that all work in the Handy Backup program is a step-by-step procedure: moving to the next stage is possible only after performing certain actions at the previous stage. This is a fairly convenient mechanism that allows you to easily and quickly do what you need, and, in addition, makes it much easier to use the program.

To create a hard disk image, you need to create a corresponding task. To do this, you need to execute the main menu command File? New task, which is also called by pressing the key combination Ctrl+N, or click the corresponding toolbar button. When you perform any of the above actions, the New Task Creation Wizard window will open on the screen, shown in Fig. 6.32.

Rice. 6.32. New Task Wizard

To create a hard disk image, you need to set the switch at the first stage of creating the task Select task type to position Backup task(this value is selected in all cases where a backup needs to be performed, regardless of the type of data being copied). To go to the second stage you need to press the button Further. In the window that opens, click the button Add, and select the command in the menu that appears Disk Image(Fig. 6.33),

Rice. 6.33. Selecting the disk image copy command

As a result, the contents of the window will look as shown in Fig. 6.34.

Rice. 6.34. The second stage of problem formulation

Having expanded the hierarchical list in the central part of this window, you should check the boxes for those hard disk partitions for which you need to create a backup copy of the image. To move to the next stage of setting the task, press the button Further. As a result, the Wizard window will look as shown in Fig. 6.35.

Rice. 6.35. The third stage of problem formulation

At this stage, you should select the type of reservation. When creating a disk image for the first time, set the switch to All selected files (full backup): in this case, the program will save absolutely all information stored on the selected disk(s) in the backup copy. If you have previously backed up this disk(s), then it is more advisable to select the option New and changed files (incremental backup). In this case, the backup copy of the disk image will contain only the changed information, which is very important in terms of the size of the backup file and, therefore, saving space. Having selected the type of reservation, proceed to the next step by pressing the button Further. In this case, the Hello Wizard window appears as shown in Fig. 6.36.

Rice. 6.36. The fourth stage of problem formulation

Now you need to specify the address where the created backup copy of the hard disk image should be saved. You can save it on a hard or network drive, a remote FTP server (in this case, you must have a valid Internet connection), on a CD, etc. The media is selected by setting the switch to the appropriate position. Further actions depend on the position of the switch.

If an FTP or SFTP server is selected to copy the disk image, fields will open below for entering the server address, user name and password, and other necessary data. However, in most cases, users prefer to save the disk image to their hard or network drive, to a CD or flash memory. In this case, in the field below Folder you must specify the folder in which the disk image will be placed. To do this, click on the one located to the right of of this field button, then in the window that opens, select the required folder with a mouse click and click the button OK or key Enter.

After selecting the path to save and clicking the button Further the transition to the next stage will take place. In this case, the Wizard window will look as shown in Fig. 6.37.

Rice. 6.37. Fifth stage of problem formulation

At this stage, you can set compression and encryption parameters for the created hard disk image. To do this, you need to check the appropriate boxes, and in the case of encryption, enter the password that will be used for access. Please note that you must enter the password twice to eliminate the possibility of a typing error. By default, both compression and encryption are disabled. After pressing the button Further the transition to the next stage of problem formulation is carried out (Fig. 6.38).

Rice. 6.38. The sixth stage of problem formulation

Here, using the appropriate checkboxes, you should specify exactly when the program should backup the hard disk image - immediately after setting the task or in accordance with a specific schedule. To create a disk image immediately, you need to check the box Run now and press the button Further. At the final, seventh stage of setting the task, the Wizard window looks as shown in Fig. 6.39.

Rice. 6.39. The seventh stage of problem formulation

Here you need to use the keyboard to enter the name of the task being created, under which it will be displayed in the task area of the main program window. After pressing the button Complete the assigned task will be added to the list of tasks and its execution will begin, as indicated by the information in the column Development/Progress of Events, as well as the contents of the log file (Fig. 6.40).

Rice. 6.40. Completing the assigned task

Once the backup is complete, the task will be assigned the status Success, and in the column Development/Progress of Events the value will be displayed for it 100 % (Fig. 6.41).

Rice. 6.41. Information about the successful completion of the backup

In a similar way, you can create not only disk images, but also backup copies of individual files and folders. If you lose data on the main storage device, you can always restore it from a backup copy. How to do this is described in the next section.

6.3.5. Restoring data from a backup

To restore data from a backup, you need to assign the appropriate task to the program. To do this, execute the main menu command File? New task or press the key combination Ctrl+N, then in the New Task Wizard window that opens (see Fig. 6.32), set the switch to position Data Recovery Task and press the button Further. As a result, the Wizard window will look as shown in Fig. 6.42.
