Help! backup/restore yielded trash...

[Steve Dyer]

Here's the scenario...

I had a 30meg disk of sources as a second drive on my AT clone which I backed
up onto high-density floppies using the SCO XENIX 'backup' command (basically
a version of dump.)  The command was:

backup 0uk 1024
(the default file system to back up was /dev/src, the disk in question.)

33 error-free diskettes later, I removed this disk drive and went through
all the procedures to install a Seagate 80 meg drive, split into 2 40 meg
partitions.  An fsck on both newly-created partitions looked fine.

I then invoked 'restor r /dev/src', /dev/src now pointing to one of these
40 meg partitions.  Quite often during the restor process, I got the error
message 'Missing address (header) block'.  This is coming from the restor
program and not from the kernel.  33 diskettes later, I performed an fsck
on the new file system, and got an incredible number of unreferenced files
and when I tried compiling News 2.10.3, I was dismayed to find mod.recipes
documentation in the middle of control.c.  There was similar trash scattered
around elsewhere.  Clearly, the process had been useless.

Does anyone know what this error for restor means, and whether it was
responsible for the problems I am having now?  I still have the old disk
around, but I want to know what went wrong before I start scraping my
knuckles to reinstall the disk and have to sit through changing 33
floppies all over again, especially if it isn't going to work again!
