I try to keep backups of everything I do at work. Trouble is the files are large, as I work with audio. Allow me to explain my issue with an example.

I have to move a folder, lets say it's 25 gigs, over to a network drive where I keep backups. On the backup drive, I've already got a copy of the folder, it's just 2 weeks older (2 weeks since last backup). What I always do is just drag the whole folder over to the backup drive and overwrite what's there. But 25 gigs takes a long time over Ethernet. And I don't need to copy all 25 gigs because there's probably only 1 or 2 gigs of new stuff in the folder. Is there anyway in Mac OSX 10.3.9 to copy only what has changed or what's different since the last backup? Asside from me going in and picking them out by hand - not only is that tedious but if I miss even 1 file (and I know I will) I could screw myself if I need to rely on that backup in the future.

I'm wondering if there's something that can be done with Apple Scripts or maybe (gulp!) the Terminal. I would also appreciate suggestions on good backup software, but would prefer to figure out a way without it.

thanks all

I only took a quick look, and all I was able to confirm is that the program "silverkeeper" does not do what you need.

Try searching google for an open source or freeware backup program that supports incremental backups.

Let us know how you make out.

There is "SuperDuper!", but for incremental backups, you need to pay something like $25.

You could also try the free CCC (Carbon Copy Cloner). The old 2.3 version is a little clunky, but works a bit better than the current 3.0 beta.
