Italy. > abrunamontini@srd.it The way it looks from here is that at some point in time, someone is going to have to change tapes in the drive and that's inevitable. You really need some jukebox. Nevertheless, you might what to backup your data to a separate disk by changing the tape device in your config file and then cpio that image to tape at a convenient time. Recovery requires a cpio back to disk and a restore. It is quite true that disk backups aren't much of a backup but if your applications are read intensive (as opposed to write intensive) then it might be worth a try.
