Disk retention
Indicates how long the backup save sets, journal and log files from backup
to disk should be kept.
The backup procedure ensures that a "full" backup is always available.
Example:
The disk retention is 4 days and a full backup is made once a week. Backup manager will then adjust the disk rate to 7 days, so that there is always a full backup available.
