It might not be much data. Look at your redirected blocks, and if they are
going up look for a new drive.
If you have space on the other volumes to accommodate it, try migrating
data off that volume so you can delete and re-create it, then move the
data back. If you don't have space available on the other volumes,
then tape is your only choice. Make a backup and verify it (do a test
restore to be sure) before you delete the volume.
One other thought: If compression is enabled for that volume and your
compression algorithms are scheduled to run concurrent with your
backup, that can be a problem.
