Stand alone backup

[Petran Bisschops]

Dear all,

What I am trying to do is to make a standalone backup from the system disk and put the resulting save set on an arbitrary data disk for storage (save set).

I booted standalone backup from a data disk and issued the following command:

$ back/image/ver dkb0: dka0:b.sav/sav

where dkb0 is my system disk and dka0 is a data disk with a normal files-11 formated disk structure that is already populated with files but enough room to hold the backup save set.

I get the following error message:

$backup-f-savsetclu save set disk cluster factor must be 1

Can somebody tell me if this is at all possible? Looking at the examples in the system manage manual the command

$back/image/ver dua1: mua0:backup.bck/re/label=pppp

should work but then again mua0 is a tape. Is there a difference on how a tape is handled as oppose to a disk as destination.

I know it is possible to restore a saveset to a disk which is the other way round. Something like
$backu/imag/ver dkb0:back.sav/sav dka0:
where dkb0 is a CD.


If I try this with a running system using the backup command, it works. Is there a functional difference between the VMS-backup command and the backup command available via standalone backup?

Your help would be much appreciated.

Regards,

Petran Bisschops

Petran,


$ back/image/ver dkb0: dka0:b.sav/sav


The error is in the output specification: it is lacking a directory spec.

If you want it to go to the top level of the disk, make that:
$ back/image/ver dkb0: dka0:[000000]b.sav/sav

or create a special dir, and use

$ back/image/ver dkb0: dka0:[]b.sav/sav

success!

Proost.

Have one on me.

There is no big difference between stand-alone backup commands and running VMS system backup commands.
But maybe you missed something.
I will give you an example how to backup dka0: to some save set on dka100:
After standalone boot:
$$$ mount/over=id/nowrite dka0:
$$$ mount/over=id dka100:
Create some directory on dka100. Creating save set in disk root may confuse you, but you can do it.
$$$ create/dir dka100:[backup]
$$$ backup/image/log dka0: dka100:[backup]dka0.bac/save
To restore save set:
After standalone boot:
$$$ mount/over=id dka100:
$$$ mount/foreign dka0:
$$$ bacup/image/log dka100:[backup]dka0.bac/save dka0:

I did backup and restore like this many times and never had problems. VMS backup is something superior. No OS has better backup utility.

(Just a minor note as I feel the main point to your question was already addressed)

> $ back/image/ver dkb0: dka0:b.sav/sav
...
> %backup-f-savsetclu save set disk cluster factor must be 1

You have inadvertently tried to create a "sequential-disk save set", which was useful with small, removable media, but as you can see, did not keep up.

Hi,

I have tried the following according to Jan's advice:

Booted standalone backup and got $ prompt.

$back/image/ver dkb0: dka0:[]b.bck/sav
$back/image/ver dkb0: dka0:[000000]b.bck/sav
$back/image/ver dkb0: dka0:[kits]b.bck/sav

All of these attempts failed wit he error message as stated in my original post e.g.
$backup-f-savsetclu save set disk cluster factor must be 1

Vladimir:
if I boot VMS from the system disk, then of course your commands would work. But i have standalone backup booted to make a 100% copy of the system disk. During Standalone backup, only the backup command is available.

Uwe,
Can you elaborate on that? Does that mean I have to adjust my backup parameters or is it just not possible to do what i want using a 'normal' build in disk as oppose to a removable media.

Cheers,

Petran

[Uwe Zessin]

did you mount the target disk before executing BACKUP?

[Petran Bisschops]

Hi,

Uwe, I am using/booted stand-alone backup in the above problem. Only the backup command is available then.

Cheers,

Petran.

Can you boot from a (relatively recent) VMS
installation CD-ROM to get the real-VMS
BACKUP (with the "$$$ " prompt VF mentioned)
instead of the old, more limited, Standalone
BACKUP? ("BOOT /10000000 ",
or something like that. Maybe "/R5:10000000",
if your box is more modern.) The V7.3
Hobbyist CD-ROM works, so a real VMS V7.3
installation CD-ROM should work. (When did
this feature first arrive?)

Can the real (old) Standalone BACKUP do this
as requested? How would you mount the disk?
Isn't it pretty much limited to a /IMAGE copy
or restore to a disk?

[Petran Bisschops]

Hi,

To supply some more information,

The 24*7 production vaxes we have are quite old 4000-106 models running VMS 6.2. They have no CD-ROM attached - only a tape device.

Cheers,

Petran.

As I don't see a way to make an old Standalone
BACKUP do what you want, I think that you're
doomed to boot real VMS from another disk. A
VMS V7.3 installation CD-ROM would normally be
easiest (a VAX 410x has SCSI built in, doesn't
it?), but you might need to add a small disk,
install VMS on it, and then boot from there
to do the real work. Especially if you can't
easily add a CD-ROM drive, or if you can't get
a newer VMS CD-ROM. (Unless the
boot-real-VMS-from-CD stuff is older than I
think it is.)

A full hardware inventory might help reduce
the bad guesses as to what's possible.
