Hello Fred,
When BACKUP sees the file GPT.SYS (and SYS$EFI.SYS) it knows that the volume is a bootable Integrity disk. When you restore the backup it will call SETBOOT to create valid GPT.SYS boot information.
So yes, a system disk can be backed up and restored and will be bootable (note that you will need to update any saved boot entry data to allow it to be automatically booted from the EFI menu).
In fact, you should be able to restore a installation DVD to a disk and it should work.
What you can't do is *reliably* create a bootable DVD without knowing the magic needed to create the El Torito boot information. We are looking at providing a way for a customer to do this for the handful of legitimate uses for it.
Thanks for that explanation, which makes a lot of sense and explains why my recent efforts to build a bootable DVD failed.
FWIW, the reason I want to do this is to create a "standaone backup" DVD. This is essentially a copy of the VMS distribution disc, set up so that instead of displaying an installation menu, it runs a command procedure to backup (and optionally restore) all the system's hard disks. I've provided a similar disc to some of my VMS support customers so they can backup and/or defragment their Alpha systems.
Regards,
Jeremy Begg

If we look at other operating systems, you can download various Linux

However, you cannot do that (except as an early adoptor perhaps) for
Windows, OS X and probably quite a few others. In this regard VMS is the
same. The only times I have acquired an early release of VMS were via a
non-official looking tape from the local DEC/Compaq/HP office.
If you have the appropriate level MSDN contract with Microsoft, all of
their products are available for download, both current and pre-release
versions.
Microsoft charges more for actually shipping the CD-ROMS/DVDs.
I stand corrected.

Following John M's comments further up this thread, I am right in
thinking that it's ok backing up an installed system disk using BACKUP/
IMAGE/NOALIAS and this will give a working disk when restored, aren't
I?
