This isn't the final system it will be attached to, that is currently running our old backup system. So while it is a pretty old and crap machine, it was the best box that I could temporarily pull to give bacula a go on - the SAS controller we have is PCI-X, but the risers in most of our servers are PCI or PCI-E, seemingly, which severely limits my choice :( bacula-fd was on a dual core 3.2GHz Pentium D with 4GB RAM, connected via a GigE switch. I did the testing while the load on the network was minimal. (e.g. at 2am while I was suffering insomnia :) I may be able to steal use a Core 2 Quad with 4 GB to give that a go for a bit.... > Also I would test the raw drive speed of your tape drive / controller setup. > > Put a blank tape in the drive and use dd to dump bytes to the device. > When I first tested my LTO2 archive I did something like > > dd if=/dev/sda of=/dev/nst0 bs=1M > > and I got around 35MB/s. Sure, that's the first thing I did when I got the drive ;) I got 80MB/s, admittedly still some way off the supposed 120MB/s. > To achive 120MB/s you will have to do that from a raid(0,5,6).
