Version cleanup rules
Acronis True Image 2015 allows you to choose from the following backup schemes:

Single version (p. 42) - select this scheme if you want to use the smallest backup storage.

Version chain (p. 42) - this may be the optimal scheme in many cases.

Incremental - select to create a full version after every five incremental versions. This is the
default scheme.

Differential - select to create only differential backups after an initial full backup.

Custom (p. 43) - select to set up a backup scheme manually.
You cannot change the backup scheme when backing up to optical media such as a DVD/BD. In this case,
Acronis True Image 2015 by default uses a custom scheme with only full backups. This is because the program
cannot consolidate backups stored on optical media.
4.3.2.1 Single version scheme
This backup scheme is the same for both disk backup and file backup types (except scheduler
settings).
The program creates a full backup version and overwrites it every time according to the specified
schedule or when you run backup manually.
Backup scheduler setting for disk backup: monthly.
Backup scheduler setting for file backup: daily.
Result: you have a single up-to-date full backup version.
Required storage space: minimal.
4.3.2.2 Version chain scheme
This backup scheme differs for disk backup and file backup types.
