I would be more worried if my backup storage didn't have enough room for at least a full fresh and unique backup from one client. - If it doesn't and something unexpected happens (user fills the whole disk with something, malware encrypts all data = changes everything to unique files, etc) then it will fill up the disk and ruin every other backup. - If you *do* have room for one client but not many more, you can always deduplicate after each client backup which should regain everything if nothing changed.
