Stored Procedure to Automate Restores – Mark IV

Here is the latest version of sp_AutomateDBRestores. Previous versions used system tables to build the MOVE clause for the RESTORE statement and to identify valid backup files. That works fine if your instance is online and healthy. This version allows a list of backup files to be input as a table-valued parameter, in the event that your primary server is unavailable and you need to restore to another location. RESTORE FILELISTONLY is used to identify logical and physical data files and RESTORE HEADERONLY validates the backup files. Code to define the table-valued parameter is contained in the procedure. Its definition is:


CREATE TYPE backupfiletype AS TABLE 
(backupfilename VARCHAR(255)
,backupfiletype VARCHAR(4));

The procedure expects backupfiletype to equal FULL, DIFF, or LOG. Any other value will generate an error.

This is an example of calling the procedure with the table-valued parameter and a STOPAT date:


DECLARE @backuptvp AS backupfiletype

INSERT INTO @backuptvp
VALUES
('C:\Backup\AdventureWorks2012\FULL\AdventureWorks2012_FULL_20140303_110000.bak', 'FULL'),
('C:\Backup\AdventureWorks2012\DIFF\AdventureWorks2012_DIFF_20140303_110432.bak', 'DIFF'),
('C:\Backup\AdventureWorks2012\LOG\AdventureWorks2012_LOG_20140303_110438.trn', 'LOG'),
('C:\Backup\AdventureWorks2012\LOG\AdventureWorks2012_LOG_20140303_110444.trn', 'LOG'),
('C:\Backup\AdventureWorks2012\LOG\AdventureWorks2012_LOG_20140303_110500.trn', 'LOG')

EXEC sp_automateDBRestoresWithFileList 
@sourcedbname = 'AdventureWorks2012',
@restoredbname = 'AdventureWorks2012test',
@droprestoredb = 0,
@noexec = 1,
@stopat = '2014-03-03 11:04:43.878', 
@TVP = @backuptvp

Currently, the MOVE clause will use the physical data file of the original backup. If you need to restore to a different location, execute the procedure with @noexec = 1 and manually edit the restore commands. I will be posting an update shortly that will allow physical file names to be passed in as parameters.

As usual, I hope you can put this code to use. If you have questions or comments, use the comment link on this page.
