automated script backup environment shell

Hi

we have installed in a multiserver configuration a BPC 10.1.4.3 (last patching release)

I suggested to the customer a backup automated configuration using the wiki documentation

How to automate backups on BPC for Microsoft - Enterprise Performance Management - SCN Wiki

The script works and it is very useful but we have a difference if we do a manual backup through server manager or script.

In the first case (server manager) the output is correct with the 3 components

folder FILEDB

folder WEBFOLDERS

folder DB.bak

In the folder filedb we have also a file called (for default environment) EnvironmentShell.BUI.

If we use the script we have the same folders but inside the FILEDB there isn't this file.

Is the env*.BUI mandatory for a restore? Any suggestions to obtain this file also using the script backup?

Thanks

Nick
