Has anyone been doing work  of using  WORM optical  disks for backup?
Their high density would allow you to do  level 0  dumps with minimal
media swapping.  It would take only one disk per Super Eagle (if your
super eagle is still working :=)) 

Severl days of level 9 dumps for a whole file system could be done on
one disk.  Thus allowing you to have the  automated incremental dumps
at nite.  

I suspect though that having something like  600 Meg  disks with WORM
properties would bring up some new concepts of backup....  

A SCSI WORM drive cost less than most 6250bpi tape drives!   Media is
a bit pricey but comparable to all those 2400  foot reels  we are all
using.
