Hello VMS folks,
just a very simple question, what does a command like this do:
BACKUP MULTIA_V72.BCK/SAVE DVA0:/IMAGE/VERIFY
That takes a backup file (multia_v72.bck) from the current directory,
and restores it onto DVA0:, and then makes a second pass to verify
what it put there matches what's in the saveset.
(it's alpha vms, so not sure whether floppy is named DVA0: on VAXen,
too).
The controller specifies the name of the floppy drive, so it can
vary from machine to machine.
I know basicaly what this does, my question is whether the .BCK file has
some special format or whether UNIX command like this:
$ cat MULTIA_V72.BCK > /dev/diskette0
or
$ dd if=MULTIA_V72.BCK of=/dev/diskette0
is equivalent.
Nope. It is a special format, and not the same format as a disk image.
If it's some special format, were it possible that
you issue this
command for me on some VMS and grab the diskette raw file and make it
available for me? the image is available at
http://www.kotelna.sk/freddy/multia_v72.bck (1419264 bytes).
Cheers,
Sorry, no floppy drive available to me...
