Hello there,

I have a customer who wanted to restore some DBs multiple time per month from production to different stages (dev, test ...) and doesn’t want to delegate the rights with EM or to the console to the devs (surprised Pikachu face). Nor spend hours behind their screen to do it themselves. So i created a script that can be scheduled (windows task) or triggered with their own automation tool.

As the source databases are split with multiple NDF I had to figure it out. So here it is, it's far from "State of the Art" script but it does the job.

(I have a "vaulted" version that can pick credentials from an encrypted file but I'm not that happy with it so here is the script without it. Feel free to improve it.)
