That makes a big difference in internet usability (at least in my experience). Rsync (as done with BackupPC) tends to max out your connection speed, making web browsing slow.

The data will essentially be available forever if I use a publicly-available torrent. Someday my encryption may end up being crackable. I'm not dealing with extremely sensitive data, just family photos and stuff.
