Parameter
Meaning
Clean up archive
Specifies how to get rid of old backups: either to apply retention rules (p. 74)
regularly or clean up the archive during a backup when the destination location
runs out of space.
By default, the retention rules are not specified, which means older backups will
not be deleted automatically.
Using retention rules
Specify the retention rules and when to apply them.
This setting is recommended for backup destinations such as shared folders.
When there is insufficient space while backing up
The archive will be cleaned up only during backup and only if there is not enough
space to create a new backup. In this case, the software will act as follows:
Delete the oldest full backup with all dependent incremental/differential
backups
If there is only one full backup left and a full backup is in progress, then
delete the last full backup with all dependent incremental/differential
backups
If there is only one full backup left, and an incremental or differential backup
is in progress, an error occurs saying there is a lack of available space
This setting is recommended when backing up to a USB drive or Acronis Secure
Zone. This setting is not applicable to FTP and SFTP servers.
This setting enables deletion of the last backup in the archive, in case your
storage device cannot accommodate more than one backup. However, you
might end up with no backups if the program is not able to create the new
backup for some reason.
Apply retention rules
(only if the retention rules
are set)
Specifies when to apply the retention rules (p. 74).
For example, the cleanup procedure can be set up to run after each backup, and
also on schedule.
This option is available only if you have set at least one retention rule in
Retention rules.
Cleanup schedule
(only if On schedule is
selected)
Specifies a schedule for archive cleanup.
For example, the cleanup can be scheduled to start on the last day of each
month.
This option is available only if you selected On schedule in Apply retention rules.
2nd location, 3rd location,
and so on
Specifies where to copy or move (p. 71) the backups from the current location.
This option is available only if you selected either the Replicate newly created
backup to another location check box under How to back up, or Move the
oldest backups to another location in the Retention rules window.
Examples
Weekly full backup
The following scheme yields a full backup performed every Friday night.
Full backup: Schedule: Weekly, every Friday, at 10:00 PM
