TAR Fail

[Volker Borowski]

Claudio,

the DLT4000 has a capacity of 20GB and the 40GB is the capacity with an average compression of 2:1.
If you have many compressed files on this system, you might not be able to backup more than 25-30GB, because you will not reach this 2:1 compressratio.
It is most likely, that the device is full.

You can check the following to be sure:

tar cvf - list_of_file | dd bs=1k of=/dev/null

with the output of how many blocks dd did transfer, you should be able to estimate, how close you are to the end of tape.
Compare this with

tar cvf - list_of_file | compress | dd bs=1k of=/dev/null

And check this result against the uncompressed limit of 20GB.

Both commands may take a while to finish.

Hope this helps
Volker

That message tell you that is not more media. I guess the tape is not at Begining when you start tar.
