You are showing here a mountpoint (the directory where a filesystem is 
mounted). The only thing that might resemble a name on a drive is a 
filesystem label.

This failed because you are trying to label a directory instead of a 
filesystem. From the blkid output you supplied later that should have 
been

sudo e2label /dev/sdb1 backup

The command rename is meant to rename multiple files based on some 
expression (see 'man rename' for more details).

Since you mentioned you mount the drive via fstab (and I seem to recall 
that you need it that way because of some permission issues), in order 
to actually achieve what I'm guessing you want do the following steps:

sudo umount /dev/sdb1
sudo e2label /dev/sdb1 backup
sudo mkdir /media/backup
sudo nano /etc/fstab

At this point find the entry where your drive is mounted. My guess is 
you have something like
UUID=8eef3b99-c17b-4913-ae61-d34c7fd5d459 
/media/8eef3b99-c17b-4913-ae61-d34c7fd5d459_ ext3 [some options here]

Change that to look like
LABEL=backup /media/backup ext3 [your options here]

(actually you can keep the UUID=... part, but labels are much easier to 
read, just be careful not to label another drive as 'backup' unless you 
know exactly what you are doing ;)

Kind regards,
Andrei
