Custom Backup Scheme - ACRONIS BACKUP AND RECOVERY 10 SERVER FOR LINUX - UPDATE 3 User Manual

1 2 3 4
4 1 2 1
This gives us only a four day recovery interval, which turns out to be the worst-case scenario.
On day 14, the interval is five days. It increases on subsequent days before decreasing again, and so
on.

The roll-back period shows how many days we are guaranteed to have even in the worst case. For a
four-level scheme, it is four days.

Meaning
Specifies on what schedule and under which conditions to perform a full backup.
For example, the full backup can be set up to run every Sunday at 1:00 AM as
soon as all users are logged off.
Specifies on what schedule and under which conditions to perform an
incremental backup.
If the archive contains no backups at the time of the task run, a full backup is
created instead of the incremental backup.
Specifies on what schedule and under which conditions to perform a differential
backup.
If the archive contains no full backups at the time of the task run, a full backup is
created instead of the differential backup.
Specifies how to get rid of old backups: either to apply retention rules (p. 29)
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 or
centralized vaults.
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 program 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
