I know how to rename the partitions: I named them both 'backup' in the first place. I don't have one specific backup script, I use the drive from different applications for different backup purposes. I'd like the first drive I plug in to get a symlink automatically, which I think udev can do. I'm just not sure exactly how, nor how to check whether or not the symlink has already been created.

I use devices by id in my fstab to have unique mount points. Have a browse through /dev/ when the disk is connected Anton - Anton Piatek email: an...@piatek.co.uk blog/photos: http:// www.strangeparty.com pgp: [74B1FA37] (http:// www.strangeparty.com/anton.asc) No trees were destroyed in the sending of this message, however, a significant number of electrons were terribly inconvenienced.

Then in your backup script, put something like: if test -d /mounts/backup1 do ln -s /mounts/backup1 /mounts/backup elif test -d /mounts/backup2 do ln -s /mounts backup2 /mounts/backup else print "neither backup mount point exists, exiting"; exit 1 Does that make sense?

[ubuntu-uk] Symlinking to USB hard drives
Hi all, I have a couple of matched USB hard drives that I use as part of my backup strategy. At the moment they both have the same label, so they end up mounted at /media/backup. But this means I can't easily tell which drive is which, and when I plug the second in, it gets mounted at /media/backup_. I'd like to re-label the drives to backup1 and backup2, but then have a symlink automatically created at /media/backup to whichever drive was first plugged in. I think I need to use a udev rule, but other than that I'm not sure. Does anyone have any ideas?
