What do you keep in there? It's a lot easier and more space-saving to keep the 'Write Once, Keep Forever' stuff like music, e-books, photos, source-files, videos, etc in a dedicated 'archive' folder.
That archive folder gets rsync'ed to multiple backups on a daily basis. The rsync process only takes a few minutes for around 4TB because you're only backing up files that have been added in the last 24 hours.
My /home folder only contains personal documents like tax stuff, and other records. Plus stuff that I'm actually working on at present. Plus stuff like personal app binaries and config stuff. I try to keep it under 12 gigs. I just looked and it's currently at 11 gigs. That complete snapshot gets backed up daily. Snapshots are gradually deleted progressively over months, with some snapshots being retained permanently.
I definitely admit that all these could be on other drives, but in this case I have found it easier to just have everything together and make sure folders are organized intelligently. At least in this case, the overhead of having separate backup procedures for different types of data is more than the marginal overhead of simply snapshotting everything.
That said, I do have a 8 TB photography folder that isn't part of this snapshot routine.
