2.tibx, 3.tibx, 4.tibxfiles of incremental backup versions.
Additional information
Incremental method is the most useful when you need frequent backup versions and the ability to
roll back to a specific point in time. As a rule, incremental backup versions are considerably smaller
than full or differential versions. On the other hand, incremental versions require more work for the
program to provide recovery.
Recovery: In the example above, to recover the entire work from the 4.tibx file, you need to have all
the backup versions1.tibx, 2.tibx, 3.tibx, and 4.tibx. Therefore, if you lose an incremental backup
version or it becomes corrupted, all later incremental versions are unusable.
Differential method
The result of a differential method backup operation (also known as differential backup version)
contains only those files which have been changed since the LAST FULL BACKUP.
Example: Every day, you write one page of your document and back it up using the differential
method. Acronis True Image saves the entire document except the first page stored in the full backup
version.
Note: The first backup version you create always uses full method.
