My hard drive crashed May 31, 2007
My laptop’s hard drive crashed so hard, DiskWarrior didn’t even see it anymore. Some ominous purring in the morning, then a crash right in the middle of a coding session. Luckily, nothing was lost except today’s work.
Now I am looking into backup solutions :). Let me know if you have tips for backing up data on the Mac.

Try out SuperDuper! The free version is very good, while the pay version allows for incremental backups. I downloaded it when my HD crashed. :S Why do we always do backups AFTER the crash? :)
Ironically, I did a lot of research into backup solutions and strategies and wrote a lovely text file. It was on my laptop :P
I’ve heard of SuperDuper. In fact, I own SuperDuper *blush*. I really need to shuffle more data around to free up an external hard drive…
I have a second hard drive on my computers (FireWire enclosure on the Mini, second internal drive on the G5) and a daily cron job which runs ‘rsync -aEv –delete’ and emails me the resulting log file. (Make sure to use the latest rsync, using Fink or DarwinPorts or whatever, since the one which comes with OSX doesn’t actually implement -e right.)
Of course, when OSX 10.5 comes out this will be moot.
Another vote for SuperDuper!
I’m on Windows, using the free Syncback, so that’s not really useful to you. But one trick I discovered, which could be useful to you if you make it work, is to schedule your backups to start whenever your computer is idle for 15 minutes. So whenever you stop using your computer for a little while, your backups are updated. I have laptop which I don’t keep open during the night or when I’m not using it for a long time, so scheduled backups don’t work so great — incremental backups after a few minutes of idleness works really well in that case.
