Availability of the backup options

The set of available backup options depends on:

 The environment the agent operates in (Windows, bootable media)

 The type of the data being backed up (disk, file)

 The backup destination (networked location or local disk)

 The backup scheme (Back up now or using the scheduler)

The following table summarizes the availability of the backup options.

backing up to removable transferring it to the vault

Dest: dedup.

This option is effective for Windows and Linux operating systems and bootable media.

This option is effective for both disk-level and file-level backup.

The preset is: Disabled.

To protect the archive from unauthorized access 1. Select the Set password for the archive check box.

2. In the Enter the password field, type a password.

3. In the Confirm the password field, re-type the password.

4. Select one of the following:

Do not encrypt – the archive will be protected with the password only

AES 128 – the archive will be encrypted using the Advanced Encryption Standard (AES) algorithm with a 128-bit key

AES 192 – the archive will be encrypted using the AES algorithm with a 192-bit key

AES 256 – the archive will be encrypted using the AES algorithm with a 256-bit key.

5. Click OK.

The AES cryptographic algorithm operates in the Cipher-block chaining (CBC) mode and uses a randomly generated key with a user-defined size of 128, 192 or 256 bits. The larger the key size, the longer it will take for the program to encrypt the archive and the more secure your data will be.

The encryption key is then encrypted with AES-256 using a SHA-256 hash of the password as a key.

The password itself is not stored anywhere on the disk or in the backup file; the password hash is used for verification purposes. With this two-level security, the backup data is protected from any unauthorized access, but recovering a lost password is not possible.

3.4.1.2 Source files exclusion

This option is effective for Windows and Linux operating systems and bootable media.

This option is effective for disk-level backup of NTFS and FAT file systems only. This option is effective for file-level backup of all supported file systems.

The option defines which files and folders to skip during the backup process and thus exclude from the list of backed-up items.

The preset is: Exclude files matching the following criteria: *.tmp, *.~, *.bak.

To specify which files and folders to exclude:

Set up any of the following parameters:

Exclude all hidden files and folders

This option is effective only for file systems that are supported by Windows. Select this check box to skip files and folders with the Hidden attribute. If a folder is Hidden, all of its contents — including files that are not Hidden — will be excluded.

Exclude all system files and folders

This option is effective only for file systems that are supported by Windows. Select this check box to skip files and folders with the System attribute. If a folder is System, all of its contents — including files that are not System — will be excluded.

You can view file or folder attributes in the file/folder properties or by using the attrib command. For more information, refer to the Help and Support Center in Windows.

Exclude files matching the following criteria

Select this check box to skip files and folders whose names match any of the criteria — called file masks — in the list; use the Add, Edit, Remove and Remove All buttons to create the list of file masks.

You can use one or more wildcard characters * and ? in a file mask:

The asterisk (*) substitutes for zero or more characters in a file name; for example, the file mask Doc*.txt yields files such as Doc.txt and Document.txt

The question mark (?) substitutes for exactly one character in a file name; for example, the file mask Doc?.txt yields files such as Doc1.txt and Docs.txt — but not the files Doc.txt or Doc11.txt To exclude a folder specified by a path containing the drive letter, add a backslash (\) to the folder name in the criterion; for example: C:\Finance\

Exclusion examples

Criterion Example Description

Windows and Linux

By name F.log

F

Excludes all files named "F.log"

Excludes all folders named "F"

By mask (*) *.log

F*

Excludes all files with the .log extension

Excludes all files and folders with names starting with "F"

(such as folders F, F1 and files F.log, F1.log)

By mask (?) F???.log Excludes all .log files with names consisting of four

symbols and starting with "F"

Windows

By file path C:\Finance\F.log Excludes the file named "F.log" located in the folder C:\Finance

By folder path C:\Finance\F\ Excludes the folder C:\Finance\F (be sure to specify the full path starting from the disk letter)

Linux

By file path /home/user/Finance/F.log Excludes the file named "F.log" located in the folder /home/user/Finance

By folder path /home/user/Finance/ Excludes the folder /home/user/Finance

The above settings are not effective for the files or folders that were explicitly selected for backup. For example, assume that you selected the folder MyFolder and the file MyFile.tmp outside that folder, and selected to skip all .tmp files. In this case, all .tmp files in the folder MyFolder will be skipped during the backup process, but the file MyFile.tmp will not be skipped.

3.4.1.3 Pre/Post commands

This option is effective for Windows and Linux operating systems and PE-based bootable media.

The option enables you to define the commands to be automatically executed before and after the backup procedure.

The following scheme illustrates when pre/post commands are executed.

Pre-backup command

Backup Post-backup

command Examples of how you can use the pre/post commands:

 Delete some temporary files from the disk before starting backup

 Configure a third-party antivirus product to be started each time before the backup starts

 Copy an archive to another location after the backup ends.

The program does not support interactive commands, i.e. commands that require user input (for example, "pause").

To specify pre/post commands

1. Enable pre/post commands execution by checking the following options:

Execute before the backup

Execute after the backup 2. Do any of the following:

Click Edit to specify a new command or a batch file

 Select the existing command or the batch file from the drop-down list 3. Click OK.
