From what I've been able to gather from the forums and the wiki, when doing backups with zmbackup, you only have the option of restoring a whole "mailbox" (i.e., a user's entire account).

Is there a way to restore only a single folder within an account? I have no idea how, but we have users that manage to delete a folder or two every so often and call us to have it restored.

If you restore an account from backup in-place, will it just add the items from the backup which are missing/deleted, or will it modify items received since the backup was made?
