How do I transfer a database, from a Production Server to a Staging/Development Server?

Hi there.

What is the easiest, simplest, and most secure way to tranfer one database, from a Production server, to the same database name on a Staging server?  

It must be automated - so I can schedule it for 3am daily, and also click "Go" and run it on the fly.  
It must also leave the Source (Production) available as this is a 24x7 environment.

My first thought, upon opening SSIS, was to use the "Transfer Database Task".  But that is getting all weird on me.  I cannot specify or create "DestinationDatabaseFiles" at all, and when I hit "OK" with what I have, the red-X circle is still on the task, complaining that "At least one source file must be specified".  But there are 2 source files listed.  So what is going on.

Thank you greatly.

The most common solution for your task is a "Database Mirroring" - http://msdn.microsoft.com/en-us/library/ms189852.aspx. It is a process of backuping and restorig a database periodically

The more advanced solution is a "Log Shipping" for near realtime mirroring:  http://msdn.microsoft.com/en-us/library/ms188698.aspx

Is there an SSIS solution... does Transfer Database Task actually work, or no?

Also, Log Shipping is not realtime, it's only as often as transaction logs are created - yes?

The other thing is that we'll need automatic as well as manual capabilities.
In other words, Staging will probably restore on a daily basis.
Development needs to restore "on demand" - so it might be today, then 3 weeks from today, then 2 months after that.  Purely on a "by request" basis because Development is, well, being developed.

I use a backup and restore. It is fast and it is working like a charm.

Is there a way to make a Backup & Restore a 1-click operation?  
I just want to click a single button, or right-click something and say Go, and have it be done.
The destination has its own file names, its own logical file names, etc.  So it has to be able to work with that.

That's why I like Integration Services.  But how can I get the Transfer Database Task to work?

You can script everything and save it in a stored proc to run it easily or schedule it.

Do you have an example of this script, and how would I create such a script?

Thank you emareou, let me check it out hopefully tomorrow.  If this (or close to this) does the trick then the points are yours.

Thank you emoreau for sharing your script, and my apologies for taking so long to get around to checking it out.

I can't use this.  It creates then drops linked servers, and it also uses xp_cmdshell - a big security no-no in this environment.

I just want to back up a database to a file, on a shared network drive,
and restore that backup file to another server.

It should only be two scripts.  Right?

Yes you can have one (the backup) that runs at 1AM
And the other one (the restore) that runs at 2AM (if your backup takes less then one hour to complete).

Or I can put both scripts into a Maintenance Plan or SSIS package or Job and execute the first then second.

if the 2 servers are not linked, how will you launch one process from the other server?

To resolve this issue,
we created a Job.  It runs a batch file as CmdExec.  the batch file can run Backup database and Restore database on 2 different servers.
This is one step better than xp_cmdshell...still not my optimal solution - I would have like to have an SSIS package or Maintenance Plan that could do the trick all at once, without needing Linked Servers or OS-level executables.

Emoreau I'll give you credit for answering this - you didn't directly lead me to resolution so I'm giving you a "B".  You did help me as much as anybody, though...thank you.
