This is more of a hypothetical question, but we've been using a Time Capsule to back up our Macs, and it has steadily been filling up since the year or so that we've had it.
We've since brought a few new Macs onto the network and have started backing them up to the Time Capsule as well. From what I've read, Time Machine makes incremental backups of Macs, and apparently deletes old backups to make room for new ones.
My question is twofold:
How does Time Machine decide which backup information to delete, especially amongst several Macs backed up to a single Time Capsule?
As we add more users to the Time Capsule, and it begins to fill, will Time Machine be smart enough to give new users enough space by deleting old backups from other users? If not, how can we achieve this?
