2.8.3 Version chain scheme
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.
2.8.4 Custom schemes
With Acronis Small Office Backup you also can create your own backup schemes. Schemes can be
based on the pre-defined backup schemes. You can make changes in a selected pre-defined scheme
to suit your needs and then save the changed scheme as a new one.
You cannot overwrite existing pre-defined backup schemes.
In addition, you can create custom schemes from scratch based on full, differential or incremental
backup versions.
So first of all select one of the backup methods in the appropriate box.

Full (p. 28)
Select this method if you want to create only full backup versions.

Differential (p. 28)
Select this method if you want to create backup chains containing only full and differential
backup versions.
You can configure the scheme by using one of the following options:

Create only differential versions after the initial full version - select this item to create only
one backup version chain. Automatic cleanup is not available for this option.

Create a full version after every [n] differential versions - select this item to create several
backup version chains. This is a more reliable but more space-consuming backup scheme.

Incremental (p. 28)
Select this method if you want to create backup chains containing only full and incremental
backup versions.
You can configure the scheme by using one of the following options:

Create only incremental versions after the initial full version - select this item to create only
one backup version chain. Automatic cleanup is not available for this option.
