I have some compatibility questions.
Has OpenVMS lost the ability to restore older VAX/VMS save sets, and can it restore those
from a PDP-11?

I've restored 'old' VMS savesets on OpenVMS 6.2 through 7.3. What do you mean
about 'those from a PDP-11?' -- Ian

RSTS Backup (the new one) creates VMS-compatible savesets. (I think it can also read VMS
savesets, with limitations.) Perhaps RSX does also, I don?t remember.

I'm not sure what version of OpenVMS I'm being asked about, I suspect it is 8
something on Itanium, but it might be older. I was thinking that with the move to v8 and
Itanium some of this might have been dropped.
I'd assume he means BRU sets from, say, RSX-11.
Correct, backups from various PDP-11 OS's.
Thanks,
Zane

RSTS Backup actually generates VMS save sets, the same format.

It's been so long since I've looked at any of this, I honestly don't remember.
I was thinking that RSX-11 backups would be readable by at least some versions of VMS.
RSTS Backup actually generates VMS save sets, the same
format.
That's good to know.
Thanks,

Has OpenVMS lost the ability to restore older VAX/VMS save sets,
OpenVMS vs VMS is more of a marketing driven name change than anything
which signifies any change of functionality or compatibility.
I have used (Open)VMS Alpha V8.2 to restore tapes containing save sets written
on VAX/VMS V5.2-2 without any issues. I expect I could also use the same
system to restore save sets written by even earlier versions but I don't know
for sure.
and can it restore those from a PDP-11?
I don't know the answer to that one.
Regards,
Peter Coghlan.
