While the backup filesystem is unmounted, can't you do a chmod 0 /mnt/mybackup? That should prevent accidental syncing when the backup filesystem is unmounted.
When you mount a filesystem on that directory, it should appear with the permissions of the root directory of the filesystem you have mounted (rather than the overlaid mount point directory) thereby allowing rsync to work as desired.
I thought that would make the mybackup directory inaccessible even by root.
please advise.

fi
This should work for you if you change the messages to suit.

Thanks for the script.i already use a script to check if the external hard disk is REALLY mounted.
i created a file called "am-a-file-on-the-external-hd.txt" on the external hard disk and before backup i check if that file exists.

just for info, i had twice landed into the issue where the filesystem was 100% full. The customer forgot to plug the usb or the usb was a bit loose.

i tried running the rsync...the rsync process could write on the unmounted/mnt/mybackup directory...which is bad
A disk was sliced into 6 slices with m01 being the mount point for one of the slices. This mount point was deleted with rmdir (ie. rmdir m01).
What is the easiest way to recover this mount point? (1 Reply)

Dear Gurus,
Could it be possible to have the output of df -k sorted? The df -k output messed up after recent power trip.
Also, is there any folders that I should look into to reduce the root size (other than /var/adm and /var/crash) after server crash?
Many thanks in advance.
