The motto of a good sys admin is backup often, and backup automatically, and make sure you can recover from a disaster. In general, my practices have been sorely lacking. No copies, no RAID, no external backup other then a couple random backups and dumping the databases (from MySQL) and the directory (from OpenLDAP).
I finally just went with one of the many rsync backup script/utilties: rsnapshot. There is a article about it on www.debian-administration.org. It's simple, supports remote backups using rsync over SSH, and gives you nice rotated backups. Easy, effective, automated. What more do you want?
So now the one thing I have still to do is do an external backup. The current backup is ~17GB. As much as I'd like to burn about two dozen CDs (or even 5 DVDs) with a spanned tarball, that sounds like a pain in the ass. I guess that means an external drive which I take off-site. Ah well, a problem to solve another day.
