There is an interesting article on backup in "Corporate Computing"  They
rated the following products:
Erasable Optical : <Good for archive not backup>
  Pros: excellent selective restore time, high data integrity and shelf life
  Con:  low performance, expensive 
Digital Audio Tape (4mm DAT)  <Not safe for backup>
  Pros: cheap drive and media, good performance in selective restore
  Cons: Low performance in full backup and restore, poor data integrity
9 Track  <too slow> 
  Pros: interchange format
  Cons: Low capacity per tape, bad performance, not cheap
8 mm <bad performance>
  Pros: Good capacity per tape
  Cons: Bad performance
Quarter Inch Cartridge (QIC)
  Pros: Cheap, Good performance
  Cons: only available for Suns
VHS
  Pros: Good performance, high capacity per cartridge
  Cons: Expensive
IBM 3480 compatible
  Pros: High Performance
  Cons: Low capacity per tape, expensive
Digital Linear Tape 
  Pros: High performance, low cost, high tape capacity
  Cons: new technology.

The ZD lab (Trinity College) raved about the Digital Linear Tape,
specifically the T860X by Cipher Data Products that sells for
$6,550 and works on Suns, Vaxs, and Novell NetWare.  They claim
6 GB per tape, backup rates of 26.7 MB/minute on the Sun, very
fast selective restore rates, and very sturdy tapes.          

They were pretty pleased with Metrum Information Storage's VHS
which they found to be fast (30.6 MB/minute on a Sun), reliable, 
and high capacity (14.5 GB uncompressed). The RSP-2150 costs
$32,900.
 
Has anyone tried DLT or VHS for heavy backup work??
