Then I use something like this when invoking rsync: rsync -e ssh -avz --delete Folder/To/Backup storageserver:/backup/folder/hostfolder this way, /backup/folder/hostfolder will always only have the files for the computer I'm backing up, and won't delete any files from other machines :) On my storage server I have a folder backup/ that contains subfolders that correspond to each machine I would like to backup.

Supports full two-way syncing, merging the changes from both directions, and can even support third-party diff tools to let you manually reconcile situations where a (text) file has been updated in both locations since the last sync run. Obviously you should try to avoid this anyway, my procedure is: sit down at machine x sync with y have a work session sync with y sit down at machine y sync with x work sync with x where I'm working on both x and y at the same time, I make sure to work only on certain projects/applications/filesets on a given machine, if I happen to be using say Firefox (portable) on both machines, I make a mental note as to which one is the "master" for that work session, and just hold down the appropriate arrow key in the Unison GUI before pressing "Go" for the sync job. Also great for quick-and-dirty backups to/from USB drives I know it’s an old thread but I’ve been replacing rsync with Unison for those situations where I might be updating the destination filesystem as well as the source.

sit down at machine y

It's useless and leaves a crippled backup file. You need to install the Dev tool and use CpMac or use ditto. (Or even better SuperDuper depending on the setup). From what I understand rsync should support resource forks in Leopard, but I'm not entirely sure on this.

I should make a copy of that tag for my site. I have nuked gigs of data (fortunately it was just entertainment junk)... I am still bad at my backup practices :( I love the OOPs tag.

Does anyone still use those? All the files I use are either text or binary. No need for those old school forks... Resource forks? Does anyone still use those?
