Re: [OT] best tape backup system?

[berk walker <berk@panix.com>]

And worse yet, you have to run them to the end and then rewind them if 
you are going to keep the data for long [the magnetic fields affect 
layers near them]. An array of RAID1 disks, which sleep deeply [off] 
between uses would probably be affordable, and last MUCH longer.

Just my 2 cents worth-
ya, well, that's what you get for 2 cents.
