Now that I have read in a few archival tapes and
unpacked the simple
ones (ANSI-D) I am looking at extracting files from VMS BACKUP
tapes. I found a program vmsbackup originally by John Carey at
Monash University in AU. It actually seems to understand my
tape container format, maybe because it is practically identical
to some other formats. But, it is complaining that my tape
has 80-byte header records, and it wants 256. My tapes start
out with VOL1, HDR1 and HDR2 80-byte records, then a tape mark and
then the backup save set follows. I get the message :
Invalid header block size: expected 256 got 80
So, does anyone know whether there is a version of this program that
will handle a backup tape with 80-byte header records, or is there
another program for extracting files from a VMS backup tape or
save set that will run on Linux?
This may be a crazy idea, but...Why not do it with VMS?
You can install simh on your Linux box, get VMS up and running in
probably half an hour, complete with IP networking. Mount your tape
images via simh and extract your savesets with the software that they
were written to be extracted by. :)
I don't know your level of expertise with VMS or simh, so please don't
take this the wrong way, but...if you want to do that and would like
some help, I'd be happy to help you out. I can put together a "canned"
simh VMS installation for something like this in a very short time.
