Computer housekeeping

I've been putting off doing backups for too long. Got a lot more stuff since I started torrenting, there's maybe 500gigs, mostly movies, and I just have 2 external drives, a Toshiba and a Seagate, 320gigs each. Duplicate redundant backups would be preferable, but I'll have to segregate for now til a get a terabyte drive. Ok, all vids onto the Seagate, that thing's been iffy since I messed it up on an install last year. Backup copies of important files onto the flashdrives. Maybe I'll try installing Kubuntu on the netbook once I'm all squared away.
