2. In the File Backup window, select files and/or folders you want to back up, and specify the

backup destination.

3. Click Turn on and schedule your backup if needed.

4. Click Version chain near the Backup scheme item (Version chain is the default backup scheme).

5. In the File Backup Options window, make sure that the Backup scheme tab is selected.

6. Choose Custom scheme instead of Version chain scheme.

7. In the Backup method box, select Incremental from the drop down list.

8. Make sure that Create only incremental versions after the initial full version is selected.

In that case the program will first create the initial full backup version (no matter how you set up

a backup process, the first backup version will always be the full one), and then a sequence of

incremental versions. The versions will be created by schedule (if the scheduler is turned on) and

when you manually click Back up now on the appropriate backup box.

9. Turn on and configure automatic consolidation if needed. Click OK.

10. In the File Backup window, check that all settings are correct and click Back up now.

3.11.2 Image creation mode

You can use these parameters to create an exact copy of your whole partitions or hard disks, and not

only the sectors that contain data. Note that the Back up unallocated space check box is available

only when the Back up sector-by-sector check box is selected.

 To make a sector-by-sector backup, check the Back up sector-by-sector parameter. By default

the program copies only the hard disk sectors that contain data. However, sometimes it might be

useful to make a full sector-by-sector backup. For example, you have deleted some files by

mistake and want to make a disk image before trying to undelete them, because sometimes

undeleting may create problems in the file system. Please note that this mode increases

processing time and usually results in a larger image file because it copies used and unused hard

disk sectors.

 The Back up unallocated space option becomes available if you have selected the previous

parameter, Back up sector-by-sector. By default, while performing sector-by-sector backup,

unallocated space is not included into the backup file. Enabling this option will include all

unallocated disk space into the backup.

3.11.3 Backup protection

A backup file can be password-protected. By default, there is no password protection for backups.

To protect the backup:

 Enter the password for the backup into the Password field. A password should consist of at least

eight symbols and contain both letters (in upper and lower cases preferably) and numbers to

make it more difficult to guess.

 Retype the previously entered password into the Confirm field.

 To increase the security of your confidential data, you can encrypt the backup with strong

industry-standard AES (Advanced Encryption Standard) cryptographic algorithm. AES is available

with three key lengths – 128, 192 and 256 bits to balance performance and protection as desired.

The 128-bit encryption key is sufficient for most applications. The longer the key, the more

secure your data. However, the 192 and 256-bit long keys significantly slow down the backup

process.
