Version cleanup rules
Acronis True Image 2021 allows you to choose from the following backup schemes:
Single version (p. 55) - select this scheme if you want to use the smallest backup storage.
Version chain (p. 56) - 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. 56) - 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 2021 by default uses a custom scheme with only full backups. This is because the program
cannot consolidate backups stored on optical media.
4.5.2.1 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 the backup manually. In this process, the old version is deleted only after a
new version is created.
The very first file will remain for auxiliary purposes, without your data in it. Please do not delete it!
Backup scheduler setting for disk backup: monthly.
Backup scheduler setting for file backup: daily.
