Not even with funky hard link voodoo?
Obviously it'll vary with how quickly your data changes, but I find that
storing 7 daily backups, 5 weeklies and 3 monthlies has an overhead of
only about 5% on top of what it would be for just a single backup - that
being mostly directories, which can't be hard linked.
Most of that data is static - old mailboxes, backups of VHS tapes, my
mp3 collection, all the software I download, etc, but there are a few
areas of it that change constantly, like mail spools and my current
mailboxes, log files (which I back up mostly because I'm too lazy to
exclude them) and so on.
