Restore Delta Backup with Full Backup created afterwards
How should I configure the Backup Retention when using Delta Backup and a Full Backup Interval of 20? When I set the Backup Retention to 21 and the Full Backup gehts deleted after the 22th Backup: Can I restore the Delta Backups with the Full Backup taken AFTER the Delta Backups or will all Backups in the chain before the new Full Backup be useless after deleting the initial Full Backup?
Greetings and thanks in advance.
Backup Delta always refers to the last Full Backup. So the ones before the Full Backup can no longer be restored on a backup made after them
@hannes Full backup interval (and Force full backup in the schedule settings) forces the job to do a full export of the disk and not a delta based on a previous one.
It is not impacted by the retention as XO will always makes sure every chain has at least a full export at the beginning so that all backups are viable.
Which means you will have multiple full backups, always one at the beginning, and, those that have been triggered by the settings above.
