ACRONIS Backup & Recovery 10 Server for Windows User Manual page 134

Full backup: Schedule: Monthly, every Last Sunday of the month, at 9:00 PM
Incremental: Schedule: Weekly, every workday, at 7:00 PM
Differential: Schedule: Weekly, every Saturday, at 8:00 PM
Further, we want to add conditions that have to be satisfied for a backup task to start. This is set up in
the Conditions fields for each backup type.
Full backup: Conditions: Location available
Incremental: Conditions: User is logged off
Differential: Conditions: User is idle
As a result, a full backup—originally scheduled at 9:00 PM—may actually start later: as soon as the
backup location becomes available. Likewise, backup tasks for incremental and differential backups
will wait until all users are logged off and users are idle, respectively.
Finally, we create retention rules for the archive: let us retain only backups that are no older than six
months, and let the cleanup be performed after each backup task and also on the last day of every
month.
Retention rules: Delete backups older than 6 months
Apply the rules: After backing up, On schedule
Cleanup schedule: Monthly, on the Last day of All months, at 10:00 PM
By default, a backup is not deleted as long as it has dependent backups that must be kept. For
example, if a full backup has become subject to deletion, but there are incremental or differential
backups that depend on it, the deletion is postponed until all the dependent backups can be deleted
as well.
For more information, see Retention rules (p. 31).
Resulting tasks
Any custom scheme always produces three backup tasks and—in case the retention rules are
specified—a cleanup task. Each task is listed in the list of tasks either as Scheduled (if the schedule
has been set up) or as Manual (if the schedule has not been set up).
You can manually run any backup task or cleanup task at any time, regardless of whether it has a
schedule.
In the first of the previous examples, we set up a schedule only for full backups. However, the scheme
will still result in three backup tasks, enabling you to manually start a backup of any type:
•
Full backup, runs every Friday at 10:00 PM
•
Incremental backup, runs manually
•
Differential backup, runs manually
