We have an external drive that our server backs up to nightly. It is mounted to /snapshots. We are planning to swap this disk out each week. The problem is that one drive comes up as /dev/sdc and the other as /dev/sdd. In the fstab the mount is set to /dev/sdc. Before backing up a scripts runs to mount /snapshots which gets its mount point from fstab.
How can I get it to mount /dev/sdc one week and /dev/sdd the next week. It has to be automatic as the people who swap the disk over will not be going into the terminal.
