I was under the impression that rsync was very smart about updating the contents of a file. If (for the sake of argument) you had an incremental volume which you wrote to every night, you should be appending to the existing file (like a tape, right?). I would expect (perhaps naively?) that rsync would discover that some large chunk of the file was unchanged and mostly just transfer the newly appended data. I've never tried though. It would be interesting to test this. > Isn't the quick'n'dirty solution not just to make the individual > volume-files smaller? Say 100MB or similar.

As we're on the subject, has anyone considered running a bacula-sd in the cloud and running migrate or copy jobs to get the data across? That should be a pretty targetted approach which transfers exactly the correct data and allows simple (if slow) restores to be done from the cloud. I appreciate not every subscription service would allow you install a bacula-sd but a VM should. Might a subscription service offer a bacula-sd out of the box? You could of course do this over a VPN if need be. Would (pragmatic) security people shudder at the thought of this?
