So █████ and I did some shopping yesterday. She bought me a shiny new 400Gb external hard drive so that I could back up the 200Gb that, with over 35,000 MP3s, functions as my home music server.
The 200Gb drive was also my backup drive, so last night, after hooking up the new drive and going through the usual associated headaches to make it work, I reconfigured all the backup jobs in Retrospect to use the new external drive, and added the old external drive to the list of drives to be backed up.
Well, I started the initial backup at about midnight last night. I VNC to the home box every so often to see how it's coming along. Only roughly 44 hours left to go! Woo-hoo!
(Subsequent nightly backups will, at least, be differential.)
