free backup solutions

[schmintan]

i have quite a decent sized mp3 collection ( 40gb). i want to back it up fully, but be able to do a differential backup every month or so. is there any free software that will allow this?

If you can wait till June(ish) then Leopard will (probably) be coming out, and TIme Machine is packaged with it which looks like an amazing piece of backup software

i thought time machine was more like sourcesafe, that cached all changes to a file so you could revert to an older version. this is cool and very useful, however its not a backup solution. i want to be able to backup my mp3's to a few dvd's and store far away from my house, and to do a differential backup every month or so as i wouldnt add many songs per month to my collection.

Have you looked at iBackup? SuperDuper also has a free version, but all it will do is clone your HDD.

You could also go the home-grown route if you were so inclined.
