I'm in the same boat, and I'm only aware of two possibilities.
1) Robocopy - using a Windows client.
BUT Robocopy doesn't do file deltas - changed files are copied in
their entirety. Which isn't a problem if you don't have large
files. But if you've got a 10G file that changes often, then this
probably isn't the best alternative.
2) http://www.bvckup.com/support/ [Bvckup]
This also appears to be a Windows utility, but does handle file
delta's. I have never used this tool and so can't vouch for it in any
If you find a functional solution, that preferably can be used on the
two Linux/Samba boxes to do file-deltas and still maintain the
permissions - that would be best.
One other option that might work:
Rsync the data, and use robocopy to simply duplicate the permissions
structure. [I believe this is possible.]
This last idea sounds bat$hit insane - but hey, it might actually work
reasonably well. :)
