Simon,

Assuming you have a copy on a server drive or CD somewhere with the version of Data Ontap you're running, all you need is boot floppies (for non-flash units), and a copy of the config files (rc, hosts, exports, cifsconfig.cfg, lclgroups.cfg etc). Providing you keep a backup of the config files - many of my customers simply replicate the files in the /etc directory without all the subdirs to a folder on a couple of other servers. The config files all used to fit on a floppy.

In a full blown DR scenario you can then have the root volume online and ready within a few minutes, unless disks need to be zero'd then it might take 20-30 minutes. You can than start restoring the rest of the root volume (home directories, workgroup data etc).

The only time this wouldn't work is if you used "snap mirror to tape" for bare-metal restores rather than regular NDMP backups.

regards,

Alan.

The only benefit as I see it to having the smallest possible vol0 is recovery time. You can back up and recover the small amount of data in a few minutes on most tape devices, meaning you are up and running fairly quickly in the event of losing the volume.

However, there are methods of replicating the /etc data to another volume, then telling the filer to boot this as vol0. This would of course mean any NIS maps etc are broken until you change their paths, but the filer would be up and running quicker than if you were to have to restore the whole root volume first, and you would not be using two 72Gb disks for 40mb of data.
