Result: you have a single up-to-date full backup version.
Required storage space: minimal.
4.5.2.2 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.
File backup version chain
According to the specified schedule (or when you run backup manually) the program creates: 1 full
and 6 incremental backup versions, then again 1 full and 6 incremental versions and so on. The
versions will be stored for 1 month. After the period the program analyzes if the oldest backup
versions may be deleted. It depends on the version chain consistency. To keep the consistency, the
program deletes the oldest versions by chains "1 full + 6 incremental backup versions" after creating
a new analogous version chain.
Backup scheduler setting: daily.
Result: you have backup versions for every day of the last month.
Required storage space: depends on the number of versions and their sizes.
4.5.2.3 Custom schemes
With Acronis True Image 2021 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. 33)
Select this method if you want to create only full backup versions.
