The overwhelming consensus is that system disks should be backed up &
restored by the tools available on the installation CD: vdump/vrestore.
Once Networker (and its on-disk index) have been restored, proceed with
restoring the rest of the disks. Thanks again.
I am importuning my management to change our backup strategy before we
need the backups to do the Disaster Recovery Plan test.

| Subject: Re-creating system disk from scratch with
| Networker/DLT backups
|
| 13 months ago we demonstrated our Disaster Recovery Plan to our client
| by taking backup tapes (8mm, created with vdump) up to
| Philadelphia and
| successfully re-created our system on an AlphaServer provided by a
| company which is in business to provide backup sites (Sungard). I
| booted from the install CD, got a "root shell," did a little
| MAKEDEVing,
| mounted each disk in turn to /mnt, and vrestored from the 8mm tapes.
| Some fiddling around, a few reboots, and we were able to demonstrate
| that we could successfully carry on from Sungard's site.
|
| We're running 4.0F on a DS20.
|
| Now we need to demonstrate this again. But in the meantime,
| we've gone
| to backups done by Networker onto DLTs.
| - How do I "bootstrap" using Networker backups?
| - Is Networker bundled into the OS? This was acquired
| before my time.
| I note that
| there is a Networker distribution on the Associated
| Products CD.
| - There is an on-disk index, which Networker would not
| have access to
| until after it
| restored the file system that contains the index.
| - The System Administration manual in the 4.0F HTML
| documentation isn't
| much help.
| I recall seeing a Networker manual which hinted at
| restoring an
| entire file system or
| disk, but didn't give any details; and now I can't
| find the manual.
|
| Thanks,
| Hugh
