I'd like to backup my system before upgrading to 8.3 from 7.3-1 (Thank you Hobbyist crew). The examples in the manual and books are from hard disk to tape but I'd like to go from hard disk to hard disk but get the following error message:
$ sh dev d
Device Device Error Volume Free Trans Mnt
Name Status Count Label Blocks Count Cnt
DAS64$DKA0: Mounted 0 ALPHASYS 16017984 311 1
DAS64$DKA100: Mounted alloc 0 DATA1 71130996 1 1
DAS64$DKA200: Online 0
DAS64$DKA400: Online wrtlck 0
DAS64$DVA0: Online 0
$ backup/image
_From: dka0
_To: dka100
%BACKUP-F-IMGFILSPE, /IMAGE specification must have only device name
Is this possible and I'm just doing it wrong or should I use another approach? Thanks in advance. Cheers - Dominic |

Since you are a hobbyist, it may not matter, but the "supported" upgrade path from 7.3-1 to 8.3 is via 7.3-2. If you inherited the system from someone else, and care nothing for the contents of the 7.3-1 system disk, it would be easier (and faster) to install 8.3 "fresh"; no backup needed.

I'm assuming here that you really have mounted DKA100 "private" to the process which is attempting to run the backup; if not, you should dismount DKA100, and mount it to the process which will perform the backup. That *should* work (or try DAS64$DKA100 as the target device name).
All that being said, I notice that DKA100 already has a label on it (DATA1). I'm assuming (again) that you have no need for the "data" on that disk; if you do, it would be best to dismount that disk, and mount DKA200 as your "target" (assuming again, that there is nothing important you want to preserve on DKA200, and it is sufficiently large enough to hold the image of the system disk). |

Oh yes, one more thing, BTW, that may make your decision(s) easier.
You really should back up the system disk in a "standalone" state, by booting from the CD, and picking the correct menu option (I can't remember all the menu options right now, but I think the menu option you want will mention running commands at the "$" prompt).
You will be dropped into a "minimal" VMS environment, with no disks mounted. You will have to manually mount the disks, and run the /IMAGE backup. The advantage to running in this environment is that you get a "clean" /IMAGE backup of the system disk, with no files "open". You can then proceed to the upgrade or install of VMS from the same menu, when the backup is complete. |

I think in the standalone environment.
$ MOUNT/NOWRITE DKA0: disklabel
$ MOUNT/FOR DKA100:
$ backup/image DKA0: DKA100:/INIT

Thanks all, for your help. I think the problem is a combination of me doing it wrong and needing another approach. I'm going to experiment with the /save_set qualifier and although I have a bootable cdrom with install_min. The proof of the pudding is in the restore. Thanks again - Dominic |
