ZFS/XFS snapshot and backup differences

Subject:

Differences on how ZFS and XFS handle snapshots and backups.

Detail:

An environment with active client I/O will need to use ZFS for the Storage Pool as ZFS provides point in time snapshots that allows for a snapshot to be taken of the Storage Volume.
The snapshot is then used for the backup to the cloud while active client I/O occurs on the Storage Volume.

Unfortunately as the ZFS and XFS Filesystems and how they are implemented for Storage Volumes are very different, you cannot backup an XFS Storage Volume to the cloud and restore it to a ZFS Storage Pool.
