Need to Script for backup running configuration of switches.

here a link to a older post that I've found....
But why not invest in XMC to do it for you - that would also give you the availablility to see on one screen whether the backup was working for all the switches.
The Base version NMS-BASE-500 isn't that expensive compared to what the 300+ switches cost you.
