>100 gigabyte hard disk is less than $200 Where? I'm not even aware of a 100G disk being sold.

I think you're kinda missing the point about tape drives. You see, the tapes are *removable*. You can keep buying new tapes and writing new data onto them. >Worse, tapes don't last, they have a three year shelf life if they are stored >properly Say *what*??? This is absurd. >and the tape doesn't physically break when it winds around the spools... ? The only tape medium with any kind of breakage issues of which I'm aware is the TK50, where the hook would sometimes come off. If someone is trying to use a TK50 drive for backups today, they've got bigger problems. >Is it possible to configure Amanda to backup to a harddisk or Raid volume >instead of a tape? So, you only want to run backups for a couple of days, then forget about the whole idea??? >My last search on tape drives suggested that a high capacity unit that can >handle 40 gigs per tape is between $800 and $1000 Seems plausible - they've certain become a lot cheaper than they used to be. >I could buy a lot of ATA hard drives for that kinda cash. Oh. ATA. I thought you were talking about real disks. So when you fill up your cheap ATA disk after a few days, then what do you do? Take your machine down so you can spend another couple hundred bucks sticking on a new one?
