Subject Re: Slow snapshots with KVM

Restoring a full backup to a point in time is 'easier' with full backups.
It's heavy on storage/networking relating to the operations. Delta's
maintain a reference to their parents so full backups are what you get when
you restore from a specific delta... with the efficiency in
networking/storage as a value add. It would be nice to see delta's in KVM.
