Script to restore all dbs on a server

  • Hi,

    We need to restore total 48 dbs on sql server 2012 for a migration task.

    If we do manually restore all dbs it will take time so .

    Can any one provide me any automation scrip to restore all dbs on a server.

    many thanks,

  • I would consider doing it with Powershell here is an article that discusses doing just that: http://www.sqlservercentral.com/blogs/everyday-sql/2013/02/12/t-sql-tuesday-use-powershell-to-restore-a-database-on-a-different-server/

  • 1.Write the backup script for each and every databases and name it as backupalldbs.sql

    (use excel to get the databases list from sys.databases tables on one column to link with backup script in another column of sql.i.e by concat function in excel.Repeat the same for restore script also.)

    2.Write the restore script for each and every databases and name it as restorealldbs.sql

    3.Execute the step1.

    4.copy the files to destination server path by robocopy.

    5.Execute the step2.

    6.Fix orphan users.

    7.etc.

  • This is what I have....

    create a database called TOOLS or whatever you want.

    Create the below SP in this database. Then execute it. It will build the restore commands based on the last backups in MSDB DB. It also applies the lastest log backups so if you don't want that you can simply delete them out of the output.

    USE [TOOLS]

    -- This stored procedure generates TSQL script that will restore all the databases

    -- have been taken since the last database backup, based on the information in

    -- the msdb database.

  • This may be an irregular way of doing it, but here's my process for restoring all of our databases from backup in DR. This is assuming the Log and Data files are going into the default location, plus in this scenario I've already manually restored the System databases so SQL is seeing the User databases but they're not accessible until the restore.

    But here's a paste from my DR notes in this regard. It's a very KISS method, but hopefully this helps.

    Restore User Databases

    One solution that seems to work great in testing is getting a directory listing of the Backup directory then using Excel to stage the backups and create the restore script. Below are instructions on how to do this when restoring only full Backups, but this can be modified easily enough to also import Transaction Logs if they exist.

    -On server run ‘cmd’ as Administrator

    -‘cd’ do the backup drive

    -Run this: dir . /p /s /b /o:d /T:C > dr_dir.txt

    -Open Excel and copy results of ‘dir’ command into A2 (Full Path) and create the following other columns:

    oB2 (Extension): =RIGHT(A2,3)

    oC2 (Filename):=TRIM(RIGHT(SUBSTITUTE(A2,"\",REPT(" ",99)),99))

    oD2 (DBName):=LEFT(C2,LEN(C2)-37)

    oE2 (Date):=LEFT(RIGHT(C2,29),17)

    oF2 (Restore):="RESTORE DATABASE [" & D2 & "] FROM DISK = '" & A2 & "' WITH STATS = 10"

    -Sort by B and remove rows where file extension not equal to BAK

    -Sort by E and remove rows where backup date is older than 24 hours (depending on when copied to UNC)

    -Sort by A and this should be the backup scripts in F for each instance. Remove any that aren’t part of DR or not needed.

    -Copy column F into SSMS after Master is restored and execute. If all folders exist on the server as they do in Production all databases should restore with no problems. If a database generates an error saying
