Yes, I thought about LD as a solution, but presumably I'd then have the issue of tens of devices mounted, how would I present that in a hierarchical structure suitable for browsing via either decline or wasd web server?
Thanks for the suggestions.

An ld device is a nice target for an image backup. I prefer a dd on Tru64 and move the output file to a vms system where it can be mounted as an lda device. no bytes wasted...

Correct. But to do that, /IMAGE wants a whole device both in input and output.
And that's not the OP situation, if I'm not wrong...

Or stay with VMS, create a logical disk of 600 MB and backup/ image

OK,
So obviously having asked the question I got further by examining the
BACKUP manual in greater detail.
It seems the command I need is:
BACKUP/VERIFY/LOG DKA400:[*...] DSA3:[MEDIA.VAX_MEDIA.VAXBINDEC95...]
The presence of the '*' in the input specifier causes the directory
structure to be preserved in the output directory.
*However* I still haven't solved the issue of timestamps. I'd like to
preserve the original file timestamps, but whether I use this version of
BACKUP or by saving to and then restoring from a SAVESET I still get
modification times of the current date.
Anyone know how to get round that issue?
Cheers, Mark.
If you have a unix system use the dd command

Guys,
I'm trying to find the 'best' way to archive the contents of the CDROMs,
and failing to find a solution.
Using COPY DKA400:[000000...]*.*;* DSA3:[MEDIA.VAX_MEDIA.path...]*.*;*
works but doesn't preseve the timestamps.
The obvious solution is to use BACKUP, but a command such as:
BACKUP/VERIFY DKA400:[000000...] DSA3:[MEDIA.VAX_MEDIA.path...]
which is what the help would have you believe does the right thing doesn't
work - you get a weird file structure where files in subdirectories are
created in the top of the destination and the directory structure is only
partially created.
Am I doing something obviously wrong here?
Cheers, Mark.

I think that BACKUP updates the modification date by design and that's not
avoidable. However, after you've done your backup copy, you could always
change (almost) any date you want with SET FILE/ATTR=xxxDATE=... Just create
some DCL procedure that scans the input medium and sets the corresponding
output file date the same as the original. :)
HTH, :)
