Retention Policy

A retention policy defines the number of restore points to keep on your extents and is configured in the Specify Backup Storage Settings step of the backup job configuration wizard.

The restore points that fall under the retention policy will be removed from both the extents and object storage repositories in the following manner:

  • An earliest restore point will be removed from the backup chain on the associated extent.
  • Data blocks that correspond to the restore point that is being removed will be purged from the object storage repository upon the next offload or copy session.

Make sure that an object storage repository has not been put into maintenance mode, as this mode prevents synchronization of the on-premises backup chain state with that of object storage.

For more information about the offload and copy sessions, see Moving Inactive Backup Chains to Object Storage and Copying Backups to Object Storage respectively.

  • Immutable blocks of data are removed after the immutability period is over.

When a retention policy encounters immutable copied/moved blocks of data, it removes such blocks from the associated backup files on the extents only and then updates indexes, informing Veeam Backup & Replication that these blocks no longer exist and must be removed from object storage once mutable.

For more information about immutability, see Immutability.

  • Associated indexes will be updated for consistency purposes.

For more information, see Indexes.
