Automatic Backup script (Pre-NetRestore)

[Oneota]

Hello! I’m writing a script that my workers can run to backup any important information on the hard drive of a machine before they NetBoot and NetRestore it. Basically, I want it to back up any apps that aren’t on our image, anything the user might have in a Media Storage folder we’ve set up, and any local users (we use mostly network users, but have some local accounts for special purposes). My script thus far is this:

[Problem in question fixed, but see the post below for my current question]

Hello again! I’ve figured out my problem that prompted the original post. I thought I’d post my current version (which is pretty close to done, but not quite) and invite any feedback on programming style, etc. Anything you gurus would improve upon?

Thanks!

(* Pre-Restore Script Design

1) Check Current Computer Name – if it starts with 00, then the machine was reimaged without it being in the DB. Notify user to ensure it’s in the DB now.
2) Check for pre-existing backups on TechComm/User Backups.
a. Has this script already been run?
b. Can the old backup be deleted?
3) Check for mobile or home/home accounts.
a. Need to find some way to back these up automatically
b. Also back-up the appropriate NetInfo record(s)
c. Post-Restore needs to be able to restore:
i. files w/intact permissions
ii. NetInfo records
4) Check for stuff in Media Storage
a. Post-Restore should copy back with 777 permissions
5) Check for non-standard apps
6) Check for non-standard stuff at the root of the HD
7) Check for stuff on Mac OS 9’s Desktop
8) Look up in replacement table to see if this unit is getting swapped out
a. If so, rename backup folder to Tag ID or ethernet address of new unit
b. Post-Restore script will need to check for Ethernet address, and, if no matching backup is found, prompt user for Tag ID (or lookup ethernet address).

are you run this as a pre action for net restore or this runs before netrestore even launches?
