It is a good practice to have all the scripts you usually use in one single container. The best place is a small database, DBAdmin, which could be deployed in every SQL server instances in the company.

This script is for SQL2008 and SQL2008R2. For other versions modifications will be needed since the RESTORE HEADERONLY and FILELISTONLY have different outputs.
EDIT: Changed from ALTER PROC to CREATE PROC.
