Because you have reached the end of the tape?

Hi Dragon,

The tape is 40/80 DLT and the backup to be taken is of around 47GB.

Is it not sufficient??

Depends. How well does your data compress? Uncompressed capacity of your
DLT tape is 40GB.

Bye, Dragan

P.S. To get the drive to compress automatically, I write to
/dev/rmt/0cbn, but that depends on tape drive model.

Is the data compressed? I believe the 40/80 capacity specification
depends on whether the data is compressed or not. HP, at least, claims
a "native capacity" (which I take to mean uncompressed) of 40GB.

If that's the entire error, I'd guess that the tape file you're reading
isn't a tar file. You might verify that the tape is positioned
properly.

Do you have a log of what happened when the tape was created? If your
file didn't fit on the tape, you should have seen some error notification.

I have neither created nor am I reading that tape but the OP might have it.
