Equipment/Device: tape library where tapes are not ejected daily but remain in the tape device.
Policy: archiving can be performed with low frequency; full backups must be kept for a longer period (4 months) than incremental (2 months).
In this case, you can set up continuous recording of tape archives with the following settings:
•Retention for media pools: Protect data for [retention_period]
•Retention for media set: Do not create, always continue using current media set
This scenario can be of use for SMB organizations. Sample workflow can include:
1.Daily reverse incremental backup to disk
2.Daily backup to tape of the full on single disk
