[Samba] Rsync to samba share very slow

[Tim]

Hello list,

I'm trying rsnapshot for taking snapshots of data. It's based on rsync. While running a rsnapshot job on my member server to sync files to another the IO is very slow.

I did a mount of the samba share of the backup server on the production server. It's mounted rw with vers=2.1 and a credentials file.
While rsnapshot is running it takes a long time to finish the sync.

What could be the reason for this. Both servers are running version 4.1.16

Thanks
Tim
