Ghost allows you to choose how often a recovery set should be made and how many previous sets to keep. Is there any advantage in keeping more than one recovery set? And the less often that a recovery set is made, the more storage space that will be needed for the incremental backups in the set, so why not just create a new recovery set every month - or even weekly - rather than quarterly?
I'm probably missing something in my thinking, but I'd like to know what!
