I don't see any --stats output. It will tell you exactly how much data was involved.
A local copy means that rsync isn't networking. Rsync speeds things up by running on 2 separate computers and communicating using the rsync protocol. If you are running rsync on a single computer with the source being a mounted SAN volume and the target being a mounted cifs share then as far as rsync is concerned that is a local copy. So, either get the cifs server to speak rsync (either over ssh or with rsyncd) or just use cp. Only copying the changes isn't all that helpful when rsync has to read the whole target file over the network just to find out what is different about it. That is why --whole-file is implied when rsync isn't networking. On 10/20/2018 02:00 PM, Lentes, Bernd via rsync wrote: > > > ----- Am 20.
