Operation Manual

 Single version (p. 45) - select this scheme if you want to use the smallest backup storage.

 Version chain (p. 45) - 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. 46) - select to set up a backup scheme manually.

You can easily change the backup scheme for a pre-existing backup. This will not affect the integrity

of the backup chains, so you will be able to recover your data from any previous backup version.

You cannot change the backup scheme when backing up to optical media such as a DVD/BD. In this case,

Acronis True Image 2016 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.

Disk backup version chain

At first the program creates the 1st full backup version. The version will be kept until you delete it

manually. After that, according to the specified schedule (or when you run backup manually) the

program creates: 1 full and 5 differential backup versions, then again 1 full and 5 differential backup

versions and so on. The versions will be stored for 6 months. After the period the program analyzes if

the oldest backup versions (except the 1st full version) may be deleted. It depends on the minimum

number of versions (eight) and version chains consistency. The program deletes the oldest versions

one by one after creating new versions with the same backup method (for example, the oldest

differential version will be deleted after creation of the newest differential version). First of all the

oldest differential versions will be deleted, then - the oldest full version.

Backup scheduler setting: monthly.

Result: you have monthly backup versions for the last 6 months plus the initial full backup version

that may be kept for a longer period.

Required storage space: depends on the number of versions and their sizes.
