I have a rather pressing backup issue (aren't they all) and now I discover
that I can't seem to restore any of the backups that have been made using
vdump. We have an Ultrix box with a tape drive that rsh-es out to various
machines, including a DU 4.0 box.
It runs a command like this:
/usr/ucb/rsh "alsatian /sbin/vdump 0uf - /" | dd of=/dev/nrmt0h obs=10240
I have tried to restore this in several ways:
rsh polecat 'dd if=/dev/nrmt0h bs=10240' | vrestore -if -
rsh polecat 'dd if=/dev/nrmt0h bs=60k' | vrestore -if -
(on polecat) dd if=/dev/nrmt0h bs=10240 > backup.file
ftp file to appropriate machine
vrestore -if ./backup.file
All of these methods give me the same ##_at_! error:
vrestore: Date of the vdump save-set: Thu Nov 21 02:46:10 1996
vrestore: empty save-set
vrestore: nothing will be restored
DECthreads Last Chance handler: thread 1 exiting on status exception 0x177db005
Exception: Invalid memory address (dce / thd)
I've tried with multiple tapes, and both ufs and advfs dumps on the tape
(/ is ufs, /usr is an advfs domain). Oh and I've tried using plain old
restore, just in case. :)
So how do I restore the dang thing?! I know this isn't a unique problem,
because someone posted a similar (if not identical) problem in October.
However, there was no followup. So I'll be sure to summarize.
