问题
Is it possible to script All of the Log Shipping configuration?
For example: I need to write a job that initiates Log Shipping from two databases from server A to server B.
The job will run on Server A.
By the way both are SQL 2008 R2 Enterprise.
There's a share on server A. \serverA\Log
I Believe this is all that is needed. Is it possible to do it just by script? Do I have to initialize the databases or is there a option like SSMS to auto initialize?
Will I have to create the jobs manually? or is it configured in a way that creates the jobs and manages them?
Is it scriptable? Has anyone done anything like this? Does any one have a script to do this?
Thanks in advance.

This is totally possible, and it can be scripted out through the log shipping setup GUI. The only obstacle to overcome in the script that it generates will need to connect to both the primary and the secondary in the same script. This can be accomplished by used the SQLCMD mode commands of SQLCMD using the CONNECT command, making sure to put GOs between the connections. As a bonus you can also execute OS commands (copy, del, etc.) so you can script out the backup and restore as well. See example below.
-- Execute the following statements at the Primary to configure Log Shipping
-- for the database [primary\instance1].[mydb],
-- The script needs to be run at the Primary in the context of the [msdb] database.
