2-way rsync?

And I agree that two 1-way backup jobs would solve his issue - I gave him similar advice further up the thread.

For true bidirectional sync, DRBD is the first thing to pop in mind but I fear that with NAS custom kernels that's a bit complicated (if possible) to do. Second one is Bittorent sync, if you have a secure channel between devices of course but I don't think the duo has it in the apps, shouldn't be hard to install it via SSH though. Also I recently found my conf erased while upgrading, I don't think that's the app but that it has more to do with Netgear Package (when my mac updated the app settings remained). Data is still present though, so that's more a trouble of generating keys and getting them back than anything else. and a third one could be Unison but I didn't use it myself.

Another possibility is to do a sync directly between your client devices, and just use the NAS for backing up the synced folder.

This application has been on my "to-do" list for a while, but hasn't reached the top yet. I suspect other posters are ahead of me - it would be nice to hear what you all are using .
