SQL 2012 :: Restore Master Database For A New Database?
Jul 29, 2014
Sometime during the night last night some user account permissions were "lost". Am I right to think that restoring the master database would be the way to go? We have a 2 node 2012 cluster and I stop the cluster resource and start the db in single user mode from the active node. Somehow the sharepoint farm is still trying to connect so I can't get logged in single user. What method could I use to stop users from connecting when I don't have access to the sharepoint farm.
If one is regularly taking backups of system databases, when does it become necessary to rebuild the master database. I am looking for a situation where rebuilding the master is preferred to restoring it from backup.
I would like to restore the master database from a current backup tape but I got the error “Load database must be used in single user mode if trying to restore the Master database”. I tried to change the master database option but the option ‘single user’ cannot be changed for the ‘master’ database. Then I tried to start the SQL Server in Single-User Mode but I was not able to restore the master database from a tape. Would anybody help me on how to restore the Master database like any other database? Many thanks
I am going through the procedure of restoring the master database as described in the Microsoft SQL 6.5 Survival Guide by SAMS. I deleted the master.dat file from c:mssqldatamaster.dat. I went into setup and choose rebuild master database. After rebuilding the master database, I went into setup again to add the "-m" server option to start server in single user mode so I can load the master database from backup. Then I went into Enterprise Manager to start the server. The server started, but when I try to double click on the server. It gave me the following
" A connection could not be established to [server name] - SQL server login failed."
I try reregistering the server, but gave me the same error. The SQL server is using standard security.
I do my backup using BACKUP database <myDB> TO DISK='D:BACKUPmyDB.bak' I do this for ALL my databases every day.
Another product writes every day all the files on the server to tape EXCEPT the online databases because these files are open by SQL server 2000.
Now I restore the files of the tape to the server This works well but I haven't got the online databases !! And because the master database isn't available, SQL server wont start ...
BUT I have the backup of the master database 'D:BACKUPMaster_data.bak'
How can I use this master backup to do a restore even when SQL server can't start ?
Or must I do the bakup of the master database in another way ?
When I attempt to restore a master database I am having some issues. I am using SQL Server 2000. I have set the start up option with -c -m to set the database in single user mode.
When I run the restore from enterprise manager I am get an popup window that is titled "SQL-DMo(odbc SQLSTATE:HY000)" with not message and then the database conection is lost. Thus the master datbase is appears to it was not resotred. As when I close enterprise manager and then restart the MSSQLSERVER service the database is in the same state.
Please advise on how i can get the Database restored. Thanks Chris
I was wondering if someone could help me. I need to re-install the SQL Server (due to a registry corruption). What I plan to do is to:
- Detach all databases (including master, pubs, and tempdb) - Copy databases to a different folder - Uninstall SQL Server - Reinstall SQL Server - Copy the databases back - Reattach all databases
Will that preserver all the security? (e.g. syslogins and sysxlogins) Will using an old "master" database on a new install pose any problems?
Any help will be GREATLY appreciated. Please email me at vchai@artinmotion.com
I have 2 database servers, 1 @ production and 1 @ DR site.
To restore the master database to DR on a regular basis, I have to rely on either the DBA or SysAdm to perform the restore. It's pretty expensive, as they have to dedicate some time to do so.
I'm exploring the possibility of getting the Data Centre staff to do this instead, as they are stationed at the DR site. Please advise the SQL permisssions required to restore master database.
I wish to restore master database which was located on "e:" on my server. the restored copy is residing on "f:" when i restore the backup and restart, the server does not start.
is there any way to avoid this and perform the restoration succesfully. or the process followed by me is wrong/incomplete.

How do I restore a Master Database on SQL Express?
Is it possible to put master database to single mode, if yes then whats the procedure. The reason behind the scenario is to restore master database from backup for which its strictly recommended to put the database in single mode. But I m not able to do so.
I am working on a Login migration issue. I have the Master database from the original database, that I have attached as a User Database, call it OriginalMaster. I also renamed the mdf and ldf files, before attaching, just in case.
I want to select the logins from the OriginalMaster, and using sp_help_revlogin script all the Logins out. I know there were many logins in that database. But what I am seeing, are all the Logins from the Current Master database. Which are only 7 Logins.
How can I select the logins, or script out the Logins from the OriginalMaster database?
I have this situation: -Two nodes cluster with two instances sql cluster 2012 and I need to move all on the new cluster 2012 with finally the same virtually name and instances.
It's possible to restore master order to preserve all security?
I am on SQL 2012 standard version and I am writing a script to restore database from .bak files on a network.
ALTER DATABASE DB1 SET SINGLE_USER WITH ROLLBACK IMMEDIATE
----Restore Database RESTORE DATABASE DB1 FROM DISK = 'N:SQLBackupDailyDB1_backup_2015_06_22_194002_0500494.bak' WITH REPLACE ALTER DATABASE db1 SET MULTI_USER GO
Since I have to restore about 100 databases , I am planning to put the script in a cursor. However my problem is how can I get the bak file name dynamically .
I'm working on a project where I need to build a small database and then copy it to a server at the client's site. I can't connect directly, so I have to use a VPN connection and use Remote Desktop, copy the database backup from my machine to the cloud, then download it to the client machine. The project is still in the early stages, and the client is still sending me data in CSV files and Excel spreadsheets. I'm periodically needing to do a complete refresh of the database at the client. I've hacked my way through it a couple of times, but I need to know the proper way to do it. I get errors on the restore step, telling me the file is in use.
I am having issues with Restoring the Backup of same Database on to the same server , as i know like many of you will be asking y i need to restore on same server.. Well the need came in that way , now i think i know the problem (i.e) The Orginla DB is there and also i am restoring the same DB again on that server, so .mdf and .ldf will be same .
I have an SQL .bak file and I would only like to restore specific columns as one of the columns is a free text field and is substantially increasing the size of the file. I can't restore it due to disk space constraints so dropping the column isn't possible if I can't get the table into a database locally.
I'm using SQL Server 2012 R2 and am working on configuring vendor access to a particular DB. I have a test db & (what will eventually be) the production DB. I've configured security for the test DB and want to back that up, then restore it (including all settings) to the prod one, renaming it to the prod DB name.
We have one database with Filestream enabled. There is one table "dbo.files" which uses Filestream.
We created a filestream filegroup Filegroup1 and added 3 data containers to it. (3 filestream data containers within the same filegroup.)
We have three LUNs F:, G:, H: each with a capacity of 2TB (That is the limitation). F: and G: are almost full. So, I restricted their growth so inserts do not happen into these data containers. Inserts are now going into H: drive which has lots of free space. Our application code prevents any sort of deletes or updates to this table. So data in the growth restricted containers will never change.
Now the database is around 6 TB in size and backups is a challenge. We are contemplating on migrating storage to netAPP and use their snapmanager console which is much faster.
However, until then, we need a solution with native SQL backups. We tried partial backups and piecemeal restore.
WE tried this on a test server :
1) Partial backup only the read-only data containers first, (F: and G:) (The plan is to back these up just once a month as this data never changes).
2) Partial backup the primary filegroup plus the third data container in the Filestream filegroup which is subject to inserts (H:)
While restoring, we tried the online restore, First, I restored the backup obtained from step 2 above with recovery option. Then I restored the backup obtained from step 1 with recovery. I see that the database was brought online. However, when I try to query the dbo.files table, I get an error stating that some files of the filestream filegroup are offline.
Hi,We are planning to create a prod environment on our Dev server, bycreating a new named instance on DEV. Our prod server is running onsql enterprise edition 64bit and dev on SQl enterprise 32bit.Could we copy all the databases from prod server includingMaster,msdb,model onto our dev server, and bring up all the databases?Does Master store information about the version of SQl server?Thanks for your helpGG
I have never done this in a DR scenario before. What I used to do in SQL Server 2000 was apply the logins to a new installation of SQL 2000 then recover the application databases. I'm using 2005 now and I'm in a different mode where I would like to be able to recover the system (master, model, msdb) to a different server with the same SQL Server 2005 build ---- 9.0.3054. I'm following the procedures from Microsoft where they state to place the instance in single user mode first then invoke SQLCMD then perform the restore. Sounds simple enough. C:> SQLCMD > RESTORE DATABASE MASTER from DISK = 'Z:MINIDRmaster_backup_200804200315.bak'
The console is coming back with a message that the backup set holds a backup other than the existing master database. So I suppose that this cannot be done and is only intended for recovery on the same instance.
We have a bunch of SQL 2012 databases which use SQl Server authentication (essentially local dev instances). Is it possible to take a backup of one of these database and then push them onto a (central) server which uses Integrated security (based on active directory authentication) using a script to change and map the authentication model in the process?
I have backed up databases from a 2008 server and now I would need to restore them to a 2012 , the only issue is that I need a script bcuz I have over a hundred databases.
