The retention rules are applied after creating a backup. They are applied sequentially in the primary,
the second and all next locations.
Tower of Hanoi scheme
Each backup is retained based on its level (p. 47), and then deleted. You specify the number of levels
in Number of levels.
The retention rules are applied after creating a backup. They are applied sequentially in the primary,
the second and all next locations.
Custom scheme
Each backup is retained until the rules you specify are met. Then, it is either deleted or moved.
To set up deleting the backups:

In Clean up archive, select Using retention rules. In the Retention Rules window (p. 73), specify
the rules and select If the specified conditions are met: Delete the oldest backups.

In Apply retention rules, specify when to apply the rules.
To set up moving the backups:

In Clean up archive, select Using retention rules. In the Retention Rules window (p. 73), specify
the rules and select If the specified conditions are met: Move the oldest backups to another
location. Click OK and then specify the location under Where to replicate/move backups.

In Apply retention rules, specify when to apply the rules.
You can choose to apply the retention rules before creating a backup, after creating a backup, on a
schedule, or combine these options. For the second and next locations, creating a backup means
copying or moving a backup there from the previous location.
4.5.4 Retention rules for the Custom scheme
In the Retention Rules window, you can select how long to store backups in the location and
whether to move or delete them afterward.
The rules will be applied to all the backups taken on the specific machine and put in this specific
location by this specific backup plan. In Acronis Backup, such set of backups is called an archive.
To set up retention rules for backups:
1. Specify one of the following (options (a) and (b) are mutually exclusive):
a. Backups older than... and/or Archive size greater than....
A backup will be stored until the specified condition (or both of the conditions) are met.
Example:
Backups older than 5 days
Archive size greater than 100 GB
With these settings, a backup will be stored until it is older than five days and the size of
the archive containing it exceeds 100 GB.
b. Number of backups in the archive exceeds...
If the number of backups exceeds the specified value, one or more of the oldest backups
will be moved or deleted. The minimal setting is 1.
2. Select whether to delete the backups or to move them to another location if the specified
conditions are met.
