What is the most efficient way to restore multiple databases in SQL 2008
I'm in the process of doing a large scale server migration, as such I have to move 50+ SQL 2005 databases to a new SQL 2008 server installation.
The DB guys have only given me a backup of 开发者_运维百科each database, so I have a directory with some 50 .bak files sitting in a directory (ie c:\db) that I need to restore.
I need to restore each database to the new server.
I can do this individually in Management Studio, but that would be time consuming. Is there a more efficient way of solving this problem.
So my question is:
What is the most efficient way of restoring all of these databases.
Machine background: The server is Win 2k8, with SQL 2008 Workgroup Edition, .net 4 is installed along with Powershell 2.
Thanks in advance.
Edited after comment: you can script restores, like:
restore database DatabaseName
from disk = N'c:\dir\BackupFileName.bak'
with file = 1,
move N'DatabaseName' to N'c:\dir\DatabaseName.mdf',
move N'DatabaseName_log' to N'c:\dir\DatabaseName.ldf',
stats = 10,
recovery
The two move
lines move the files to a location on the new server. Usually the names are DatabaseName and DatabaseName_log, but they can vary.
With recovery
means: bring database online without waiting for additional log restores.
To generate a script like this, click the Script button (top left) in the Restore Database wizard window, and click Script action to...
.
Write a custom application/script? You could extend SSMS or use SQL server tools to write an application that just reads these files and restores them to the database. I know it is possible in .net, might be possible using powershell scripts as well.
This is efficient if this task is to be done in a short period of time during the production migration, otherwise the overhead of writing the app is more than doing 50 restores manually! But if you are a developer and you choose manually, then shame on you! :).
