Step by step (Application + Database) backup in AX 2009

Hi All,

I have requirements to take Application and Database backup in AX 2009. Customer wants to take backup (Application + Database) from Production Server and RESTORE (Application + database) backup in Dev server.

Note : Customer mostly did all customization in USR Layer.  Little bit customization also did in CUS layer.

Kindly let me know the steps.

Please give me more shed on this.

Thanks!
