Description

Probably easiest to construct using pool-level snapshots, and computing a delta between two snapshots on the sending side.

This should really work between two otherwise unrelated Ceph clusters.

Use cases:
- backup / disaster recovery (either restore to original dc, or start operating from the new dc)
- asynchronous read-only replica on a remote site
