Folks,
 
 Tell me if this sounds rediculous. We want to make a backup
 set of Ultrix tapes. You know, we want to be cautious and
 backup our original distrbution so that is anything goes
 wrong we have another bootable tape. You know, just like
 they used to tell you in the PC world...MAKE BACKUPs!!!.

 Well, I know they have something like this in VMS-land.
 I think it's called StayBAck for Stand-Alone Backup. Is
 there a similar feature for Ultrix?

 Alternatively, is there a way, or has anyone tried doing
 the following:

 use dd to copy a whole tape to disk, then use dd again
 to copy that disk to a blank tape. Would this work
 to copy the bootblocks? Remember in booting, we'd need
 the bootblocks, Ultrixboot and something that
 acts as a bootable image, either a mini-kernel (System
 Managment in the Install menu) or vmunix.

 Has anyone ever done something like this? Is it just
 rediculous that we'd want to make a backup of a tape,
 or another bootable tape of our urrent kernel for
 disaster recovery? The other alternative is to
 either keep a spare disk around with a full dump
 of the bootable file system, or to pray that the
 tape's never get damaged whih is just nota very
 comfortable situation. Or are we just being
 paranoid? Remember, even with a full Maint.
 Contract, the best DEC could do is give you a new disk.
 The data you'd have to replace yourself...AFTER you
 boot it up with...with...a BOOTABLE TAPE!!!!

 Of course we'd also like to protect our Fortran Tape
 and our WP tape....etc. So if anyone else has
 an idea of how to do this, let me know! I'll
 post a summary if there's enough response. So far
 24 other people have asked me the same question
 so if anyone else wants the answer, drop me a line and 
 I'll kick back the summary if there is one. Thanks in
 advance!!
