Re: question abount pre-xfer exec
You only log you would like to to mount /backup, but the actual command is missing. You should also log errors, so something like /usr/bin/mount /backup >> /var/log/rsyncd.log 2>&1 would be adequate before your line to check what is mounted. Hope this helps Hardy Am 24.09.22 um 15:15 schrob dotdeb--- via rsync: I've been using rsync for years to backup my machines both at work and at home. These days I faced a new "challenge": at work I connect my laptop to a docking station with an external usb disk. I'd like to use this disk as a backup volume.

Re: question abount pre-xfer exec
You aren't logging any stderr. That is where any error messages would go. Add some 2>&1.
