possible? scripted DB drop/restore from backup, restart

I'd like to make a tool that non-technicians could invoke if there was a
defacement or destruction of our database data for whatever reason and an
expert wasn't around to tend to things. The sequence would run something
like this:

1) Take IIS offline if necessary and drop existing DB connections
2) Back up current database to [timestamp]_[dbname]_dropped.bak
3) Restore from a known good backup
4) put IIS online if necessary

I'd imagine this can be done via script. Items 1) and 4) are the biggest
mystery. From my experiences working with the SQL Server GUI, existing
connections must be closed to the DB before backup/restore ops, and the only
reliable way I've found to do this is to stop IIS. Perhaps there is a way to
force things entirely in script. Script would be preferable if it is a
reliable way to accomplish what I'm trying to do.

Can someone suggest approaches and ideally a resource or two to read
through?

Thanks.

Hello KF,

From your description, I understand that you're trying to author some
script or a program to programmaticlly turn off ASP.NET application in IIS
server and perform database backup task in SQL Server, correct?

I'm wondering whether your database will be used by the ASP.NET application
only or if you only care about the data accessing from ASP.NET web
application? If you only care about the data accessing from ASP.NET
application, you can consider the following means:

1. stop and start IIS service as you mentioned

2. If you're using IIS6, you can also stop the application pool if the
ASP.NET application only.

here are some IIS management related script resources:

3. For ASP.NET 2.0, there is a new feature. You can put a "App_Offline.htm"
file in the certain ASP.NET 2.0 application's main directory. Then, any
sequential requests won't be processed(deny by ASP.NET applcation runtime).
You can use this feature to stop the ASP.NET application's processing.

Hope this helps some.
