I ha(ve/d) a small external hard drive enclosure which holds/held two 2 TB drives in RAID-1 mode (recently tested that it’s indeed RAID 1: The enclosure left out smoke and one of the drives now works happily in a single-drive enclosure), attache(s/d) via eSATA and is used every hour by an rsync backup run using hard links. Every evening, I run another script that cleans up most of the older backups of the last week, keeping one per day. So, yes, while at home, I also lose at most one hour of stuff, provided that nothing catastrophic happens that damages both the drive and the notebook – unfortunately until very recently, the internet connection to backup offsite was simply not there, and even with 50/10 MBit/s it will be annoying.

If you hadn't written your own script, I'd recommend you use rsnapshot [1] instead. It is based on rsync. You can set up a schedule with multiple generations. [1] http://www.rsnapshot.org http://www.rsnapshot.org

  Yeah, I stumbled over it less than a week after I had set up some nice script to delete the extraneous backups I didn’t need. At the time, my requirements for keeping backups were a little stricter, too, due to space constraints, which were not easily implementable using rsnapshot. I guess with my ‘new’ scheme of one backup/day to keep, it’d be much easier.
