How does CBS retention and deletion work, if the volumes no longer have any policy?
Applies to
- Cloud Backup and restore Service (CBS)
- Cloud Volumes ONTAP
Answer
Backup retention is managed/operated by ONTAP, it uses the same replication engine as SnapMirror (LRSE - Logical Replication with Storage Efficiency), and that mechanism is what ages off older backups when an SnapMirror update is executed. When you break a relationship, ONTAP can't update the relationship backup retention.
The removal of any backups would therefore need be done manually.
Any backups remaining in S3 would still incur charges.
