Is this a new project or something that broke all of a sudden?  Try
another tape drive (e.g. replace this one that's throwing the errors).

Must be a mistake here. You mantioned "backup" and "tar" in the same sentenc
e.

Which is it ?

You probably went "out-of-tape". dump will allow multi-volume backups.

Since this is my home system, I don't have the luxury of swapping this out
with a new drive. I only have errors when I try to tar the entire system.
I've swapped tapes, but to no avail.
It's strange, the tape is filling. I know this because after I get the error
message, I can tar -tv and find that it did backup files I made today. In
fact, it's writing about 27GB. As mentioned in someone's post to my original
post, I'm thinking maybe end of tape, but IIRC, tar will give an 'end of
tape' message or similar.

Thanks,

Joe

Ok. Use 'dump' for backup.


tar is an exchange format not very well suited for backup purposes.

Don'r rely on tar for this .. Again, dump does this better. But you already 
know that ?

No, it's not :-)

dump detects EOT and will prompt operator for another tape, they all
constitute a multi-volume backup. Some tar's does multi-reels but they
don't do backup :-)

The manual can claim that all it wants.  Actual experience says
it rarely works.  As did your actual experience.  Yet again
another reason to switch from the archival tool tar to a backup
tool like dump.
