If you're just doing a `tar -cfMp remote:/dev/st0 /`, I'd be
inclined to ask it not to back up /proc. Create a file called
tar-excludes somewhere and use <something like>:
tar -cMp --exclude=/root/tar-excludes --file=remote:/dev/st0 /
Said file might contain, among other things...

You're using DDS3 tapes in a DDS2 drive? *Raised eyebrow*
Never tried that...

IIRC, DDS1 came in two varieties - 60m and 90m. The one could fit
about 1.2GB onto a tape and the other about 2GB. Uncompressed.
Could it be that your DDS2 drive is looking at the DDS3 tape,
wondering what the heck it is, deciding its a (lowest common
denominator) 60m DDS1 tape and writing 1.2GB to it?

Get a DDS2 tape? Maybe even two, one for /crap?
