Ultra high-speed link between servers
At the moment, I backup all of my servers to one machine (JANUS), an old desktop with a 250Gb hard drive. This machine is used for staging, and I usually do a weekly backup to DVD.
I'm upgrading a few servers to Proliants, and have a 75Gb tape drive in one of them (STOR1).
Now, I'd like my weeklies on tape, but am not sure that I want to change the entire backup system to use the new server as the master.
The total backup of all machines is ~6Gb, so this is a very large hit on LAN bandwidth.
Unfortunately, it is not an option to add a SCSI card to JANUS.
Any ideas on a high-speed interconnect between JANUS and STOR1 for transferring the data? Gigbait copper? Some fiber method?
The cost should be low - I don't mind lightly used parts, but I want it to be in the $100 rage, with an absolute max of $200.
So, what I'm asking for are any suggestions for the technology to accomplish this. Also, I considered the idea of getting a gigabit copper switch, so that I could also add cards to the other servers, and have a dedicated LAN for backups, to keep that traffic off of the working (100 Mbps) LAN.
Just looking for some input, as I don't know much about high-speed networking, and definitely don't know about anything other than copper Ethernet.
