Thanks to everyone,
I found it, using the idea of making a tar file - thanks
Mogens. [I don't know why booting of a USB system didn't have the same
affect. Maybe I was careless]
The tar file was 60Gb, so I actually made it and inspected it and
found that the problem was:
* I have a big USB disk
* I Make a nightly backup to this disk of /home /etc for 2 machines.
* As it is USB. gnome mounts it under /media WHEN I LOG IN
* If the machine reboots without my log in the USB is not mounted
* The autobackup rsync looks for and fails to find /media/backup
- so it makes a new one WHICH IS in /
* I did not regard and of the /media/XXXX directories as part of / so
missed it.
So now I better fix the mounting of USB drives with /etc/fstab,
Bill
