Below is an extract from one of the reports Amanda generated:

Am I correct in thinking that this run it used 71.6% of the total amount
of tape, also the compression doesn't seem that much
(used hight-tar with best compression)
If the tapes apparently capable of holding 8.0GB (DDS2) at a 2:1
compression rate, the above seems that its not really compressing it at
all effectively.
I have chosen to turn of hardware compression as well.
What would be the best option to use for as much compression as
possible?
I know that trying to compress already compressed files can increases
the output, but this way I have to watch what I put in every directory.

Again for this it seems that rather than actually compressing it, it has
increased the original file in size (the scripts directory are only perl
scripts and downloads are just a mixture of stuff).
Would it be best to use non compression for these types of files?
