dump(8) verification ?

[john s salmi]

a point of interest has been generated here of late.  we are beginning to use
our 4.2 vax 750 as a serious development machine.  a lot of proprietary soft-
ware lives on it, and dumps are done daily.  my question is this:

has anyone hacked dump to perform a verify pass on the data dumped?  a few
of our other development systems (pdp-11's) running rsx use bru as a backup
facility.  one of the switches on the bru command line tells bru to make sure
that the tape is written as it is supposed to be written.  this does, of course,
cause a bit of hardship, as the pdp's are backed up each morning around 8:00,
and the machines need to be in single user mode for the verifications to work.

anyway, does such a utility exist?  if so, can someone point me in the direct-
ion of the source?

as always, thanks in advance...
