[Discuss] Ubuntu USB Drives appending _ to folder

[abreauj at gmail.com (John Abreau)]

Whenever this happens, the old directories will be on the root filesystem.
I suppose your script could check for that.

    mount | grep ' on /media/Nagios_Backup' | cut -d' ' -f3

will return the directory with the prefix "Nagios_Backup" that is actually
in use as a mount point.
