You mean separate power supply for additional drive(s)? Is it to switch it off after backup is finished?To protect users from their own errors, you could just backup to /var/local/backup on your existing raid5 array. To protect the raid5 array, add a spare drive on a different controller if possible to provide some failover. Add two for raid1. If you have a spare computer, backup to that. This could be your workstation. Add a drive or two (for raid1 there). Have it on a separate power supply/UPS/whatever. I found an external USB drive with 320GB. I was thinking to buy one for beginning. But now I might buy more.Then, external USB makes sense. Get three: one hot, one on-site cold, one off-site cold for disaster. Have you found an external USB drive that takes 270 GB or will you have multiple drives and use your backup software for volume management? Did you mean: one hot - all the time connected to workstation? one on-site cold - not connected but at the faculty? one off-site cold - not connected located outside of the building? This would be best and might become my next step, I just have to talk with the IT guys first.If you want, you could set up a dedicated backup server and offer backup services to the whole faculty :) Thanks, Mitja |
