Yep. I will umount the data part and retry.

This is a "ps fax | grep borg"

Ok, I'll remove it

It is an old rsync habit. When /etc/passwd is in the game I use
--numeric-ids, I often use rsync accross machines to backup and then a
--numeric-ids will keep the users.group together with the /et/passwd or
group of that machine.

Indeed there is no reason for it as the backup is invoked on the same
machine. But I can imagine that I will use borg to backup one machine
on another.

Yes, I need to run it from the commandline, in the script I use fd 3 to
write the output to a mailbody.txt file that is mailed when the script
finishes.

I will try it again tonight.
