Hi Carlo,
for any modern hardware your rates sound low.
Below is an example I get in my home system (Core2 Duo, 8GB memory, CentOS
5.4 Linux 64-bit), writing to external USB disk, with no compression.
Backing up a local disk, catalog database on the same physical disk too (not
an ideal combination).

SD Bytes Written: 164,537,630,363 (164.5 GB)

Software Compression: None
AFAIK, the GZIP9 you are using is the heaviest compression, both in terms of
expected ratio, and required cpu load. I think the Bacula documentation
mentions that levels over 6 usually result in no significant improvent in
ratio, but consume more cpu power.
Incremental will be slower than full anyway. But since it's this much slower
even in this speed class, makes me think the reason might be something else
than compression. But since it shows very different compression ratio, it
may also be because of compression / different type of the contents of the
files included in the job in average.
At first, try lowering the compression level, or totally disable it, to get
a reference that helps you restrict the possible reasons to the low
throughtput.
A guess without knowing your system: if you have a Windows client with
antivirus sw that handles every disk access, it could have a heavy impact on
this too.

Hi,
I would like to know if is true that I have so slow troughput as this:

Software Compression: 15.5 %
All my jobs have the maximum compression
Options {
compression = GZIP9 #aggiungo compressione massima
P.S. is this the maximum compression??
My backups are made on Hard Disk. I tried to use an USB, as an iscsi, as a
e-sata device but the rate is so slow..
My best throughput is less then 2Mb/s
It's all right, or there something wrong?
