I have decided to start useing software compression to see if I can get a

little better tape utilization.

I have set up the .conf file to use "server best". I ran amdump with a test
DLE with one file. The backup system log that was email said every thing

went fine.

The problem is that I do not see any information about how well the software

compression did.

I have looked through the amdump logs and the logs in /tmp but still did not
see the information I was looking for.

What log files will give me the compression or at lest show me that it
worked.

From the last two mails you sent, it seems that you are missing
the report that Amanda sends after each run.
Did you get that mail (and read it)?
If not, you have to change a parameter in amanda.conf to indicate the
email addresses where you want the report to be mailed to; something like:

 mailto  "rmcgraw AT purdue DOT edu someoneelse AT example DOT com"


In that report that is sent after each run of amdump or amflush,
you will find the information like what DLE had some results missing:

Like things needing your attention:

Look at these last three lines.
