Compressions occurs in Client.
You may test if the client version has compression enabled by default.
Do you compile by yourself the client daemon on the clients? Or you are
using binaries?

You may want to get the VXA tools from the web site, probably exabyte.com,
since they bought Ecrix. The vxaTool is the best way to control compression;
I am not sure that mt will do that. I know that here mt does not work to
eject tapes where vxaTool does.

Did you try
mt -f /dev/nst0 weof
to blank the drive.
And then possibly
dd if=/dev/s
Anyone have an idea that might help me?

Compression is enabled on the client (eg compression=GZIP), which means
that the client will write a compressed stream to the sd.
The sd can also enable hardware compression on the actual backup device
if it is available on the device.
Which is better depends on the circumstances, eg CPU of the c

Keep in mind that hardware compression is often handled by using a
particular device name (ie /dev/rmt/0c vs. /dev/rmt/0). I don't know if
this helps (and you're probably already aware of this). As for using
software compression in only some cases, that is another question.

I remember reading the code. It's file by file.

My experience with compression is that it doesn't work. I seldom get
more than 5GB over the rated uncompressed capacity.
