Wouldn't it still be more efficient to let AMANDA's planner take care of which backups go to which drives and at what times?

Thanks. That's not exactly true. I use both drives in my changer simply by running two configs simultaneously. To some extent, it's just an added level of parallelization. When I had only one drive and was using 'runtapes=2', the backups sometimes ran well into the day. With two drives, two configs, and runtapes=1, they're always done in the early AM. As to the original question, I've got ~4.8TB of used space over 4 servers (out of ~5.2GB formatted space), and back it up using a 2 drive, 19 slot AIT3 changer. With a new 6TB server arriving Monday, I'm looking hard at LTO3 changers... -- Joshua Baker-LePain Department of Biomedical Engineering Duke University
