Several posts on this thread suggest that mirroring can also cause problems. I'm leaning in this direction, but I probably won't have DVD-R for a while, so I would be going to a second hard drive. Since I didn't know what "rdiff" meant, I checked on Google and got this as the first result. Since it's Stanford, I assume it's OK to post the url... rdiff-backup Seems ideal on the surface, but now I'm back to square one with regard to kapow's question. How do you do it? In my case, I'm thinking Windows.
Following my post above, I've gotten some Sticky Mail suggesting that removable caddies can lead to a bunch of problems... that the mechanisms aren't reliable, and that the drives aren't hot swappable, so if you're not plugged all the way in you can lose data. Recommendation was to use a fixed drive, or, if I want an external, to go with a firewire drive. I'm rather fond of using an imaging system (i.e. Norton/Symantec Ghost) to DVD-R or rdiff-backup to another hard drive.
[rdiff-backup.stanford.edu...] rdiff-backup backs up one directory to another, possibly over a network. The target directory ends up a copy of the source directory, but extra reverse diffs are stored in a special subdirectory of that target directory, so you can still recover files lost some time ago. The idea is to combine the best features of a mirror and an incremental backup. rdiff-backup also preserves subdirectories, hard links, dev files, permissions, uid/gid ownership, and modification times....
