Is this a full backup job? Do you have a gigabit network? What version of bacula are you using? Have you properly indexed your database? If you do not have a gigabit network is your database on the same server as the director and storage? Are you backing up thousands of small files? Do you have software compression on? Are your computers less than 3 years old or all > 2GHz.

Bacula 2.1.X waits till the entire spool file is filled before it writes to the tape. There has been work to allow the tape drive to work while the client is running (to improve single backup performance) but I do not think that made it into the current bacula which is version 2.2.0. >This doesn't to be the case at all. A spool file is created but also the writing to the tape starts at the same time so writing speed still is very low. Are you sure that spooling is on? I believe you have to activate it in the job and the bacula-sd. It will show that it is running if you do a status storage while the job is running. How big is your spool file? My spool file is to 2GB for my nearly 100% gigabit network with my LTO2 autochanger and with spooling I get between 4MB/s to 25MB/s which is dependent on a lot of factors. Incremental and diferential jobs are usually much slower than Full because the client spends a lot of time finding the files to backup. If I backup a job with > 1,000,000 small files I generally get a lower much rate than backing up a few files that total the same size as the 1,000,000 small files. I am running my director, database and storage on three different machines with the director and storage being dual processor Opteron 248 boxes with 4GB of memory and the database (postgres) is on an athlon64 3200 with 2GB of memory. All are running 64 bit gentoo with most servers running bacula 2.1.X and clients (windows and linux) running versions of bacula from 1.38 to 2.0.X.
