Object Lifecycle Management works by defining rules that instruct Object Storage to archive or delete objects on your behalf within a given bucket. A bucket's lifecycle rules are collectively known as an object lifecycle policy.
You can use a rule to either archive or delete objects and specify the number of days until the specified action is taken.
A rule that deletes an object always takes priority over a rule that would archive that same object.

The backups feature of the Oracle Cloud Infrastructure Block Volume service lets you make a point-intime snapshot of the data on a block volume.These backups can then be restored to new volumes either immediately after a backup or at a later time that you choose.
You can copy block volume backups between regions using the Console, command line interface (CLI), SDKs, or REST APIs.
To copy volume backups between regions, you must have permission to read and copy volume backups in the source region, and permission to create volume backups in the destination region.
to do all things with block storage volumes, volume backups, and volume groups in all compartments with the exception of copying volume backups across regions.
Allow group VolumeAdmins to manage volume-family in tenancy
The aggregate resource type volume-family does not include the VOLUME_BACKUP_COPY permission, so to enable copying volume backups across regions you need to ensure that you include the third statement in that policy, which is:
Allow group VolumeAdmins to use volume-backups in tenancy where request.permission='VOLUME _BACKUP_COPY'
