From the debug file:

amanda parse the number of block but it think they are blocks of 512 bytes.

This problem is fixed only in amanda-2.5.2b1 (The MB value is used).

It's possible that amanda doesn't parse the output correctly.

What's your OS? backup tool?

Could you post a sendbackup.*.debug file?

It's probably already fixed in a newer version.

Once again the data seems to grow while it's written to the tape. But I think I figured out the problem. During the calculation of the estimates everything seems to be ok and all sizes are like the real ones on the disk. The problems start with the dumper. The dumper doesn't compare his result with the real sizes but with the real sizes divided by two because of the default compression set to 0.50. A compression to 50% isn't possible on all the disks and that why the data seems to grow.

My question is now, is this a bug of version 2.4.5? At the moment I don't get packages for openSUSE 10.1 from SuSE or the amanda homepage with the newest version. Perhaps I should try this next?

Thanks again

Did you set a 'comprate' in your dumptype? You should remove it.
Amanda will learn the compresion ratio after a few run.

For all 'info' file, you can remove the value in the 'full-comp' and 'incr-comp' line.
