You could either use rclone to sync your CephFS to S3. rsync can build the latter - see write-batch and only-write-batch options. (Unfortunately, there's not yet CephFS support for building the diff between snapshots quickly, this will do a full fs scan, even though it takes advantage of the mtime/ctime obviously.) You could also use something like duplicity to run a regular incremental backup. -- SUSE Linux GmbH, GF: Felix Imendörffer, Mary Higgins, Sri Rasiah, HRB 21284 (AG Nürnberg) "Architects should open possibilities and not determine everything."
