Another consideration is file system. Once you get beyond basic hardware, there
are a number of tweaks to look at on the software side.
Your setup isn't terrible, but there's a lot of room for improvement. As
mentioned upstream, RAM would help. It wont be a cure all, but it's a start. WD
Cav Greens are insanely slow. Black or Red are a big step in the right
direction, but ideally I'd get that pool into a RAID 1 (again as mentioned by
others.)
Last thing to consider; Just because the switch can move data at a gigabit per
second doesn't mean that it's going to be getting a gig of data per second from
the host, nor is the server going to be able to write a gig of data per second.
BackupPC isn't always moving data, especially with Rsync. There's a great deal
of time spent listing directory and partition contents, hashing to compare
existing data to potentially new. The best speeds I've personally seen are in
the 25-30 Mbps range.
Bottom line, I'd bet you're getting 4 or 6 mbps. There's some room for you to
improve, but you're not going to see backups in the 50-60 Mbps range.
