Fixed retention type for SLP operations
The Fixed retention indicates that the data on the storage is retained for the specified length of time, after which the backups or snapshots are expired.
An image copy with a Fixed retention is eligible for expiration when all of the following criteria are met:
The Fixed retention period for the copy has expired.
All child copies have been created.
All child copies that are mirror copies are eligible for expiration.
The Fixed retention period is always marked from the original backup time of the image. For example, if a tape device is down, causing a 2-day delay in creating a duplicate tape copy, the expiration time of the duplicate copy is not different due to the 2-day delay. The expiration time of the duplicate copy is still x days from the time that the original backup was completed. It does not matter when the copy was created.
If the replica copy has any dependency on its source copy, and the Fixed retention type is selected for the replica copy, then whichever copy (snapshot or any replica copy) in the SLP has the highest retention level, that copy's retention level is set as the retention level for the snapshot copy and all the replica copies in the SLP.
