How to Restore SQL Server Master Database With or Without Backup

To reduce failed attempts from users, we will talk about restoring the SQL master database in this post.

Despite being a popular relational database management system, SQL Server often encounters corruption and other issues. For this reason, SQL users often complain about being in trouble and unable to perform some simple tasks. However, it is not always the fault of SQL Server that the users cannot restore the SQL Server master database seamlessly. Sometimes, users do not have sufficient knowledge about the process either, and that is what stops them from successful database restoration. To reduce failed attempts from users, we will talk about restoring the SQL master database in this post. Continue reading to learn about the processes in detail.

Why Do You Need to Restore SQL Master Database?

Master database file (A.K.A. MDF file) is the main user database file that contains all the major data in it. If the database gets infected by a virus or encounters some other severe issue, it is the database file that gets affected in the beginning. In case of database corruption or some other errors, master database restoration is the only solution users are left with.

How to Restore SQL Server Master Database

Users who face the need to restore MDF file may or may not have a backup file with them. No matter how strange it may seem, many database admins do not regularly back up their SQL database. Hence, they do not have any backup files to restore. We will talk about both situations and how users can restore their master database with and without a backup file.

Restore SQL Server Master Database from Backup File

**User’s Query: **“Hello all. I am in urgent need to restore SQL master database. But sadly, when I try out the manual technique, I fail to perform the restoration process. I started the process by putting the Server in Single user mode, but after performing one to two more steps, I encountered some error. Not sure where I made the mistake that the process got aborted. Can you suggest how to restore master database from backup manually? I am using SQL Server Enterprise 2005 version and my operating system is Windows Server 2008 R2.”

If you have a backup of the master database, then you can easily restore the MDF file using the manual method. Make sure the backup does not contain any corruption issues. The process is short and does not need the help ofany extra tool. Here is the guide to manually restorethe master database in SQL Server.

  • Put your SQL Server instance into the single user Mode.
  • Run this TSQL command to restore the master database:

“RESTORE DATABASE master FROM<backup_device>WITH REPLACE”

The “replace” command means the restoration process will continue even if there is a database with the same name, and the existing database will be removed.

Note: When the restoration process is complete, SQL Server instance will close down. You have to switch the single-user parameter before starting the Server again.

Restart SQL Server and perform other recovery tasks like database attachment, other database file restoration, etc.

Restore Master Database Without Backup File

User’s Query: “I am a SQL Server 2016 users and my database has become corrupt severely. The database contains a lot of business-critical data, so I cannot do away with the MDF file. Is it possible to restore SQL Server Master database without backup file? Please tell me as I am okay with both the manual and the automated method.”

It is possible that you may not have the MDF file backup with you. Earlier, users had a troublesome time without a backup, but not anymore. Now, they can easily restore the master database from their corrupt or damaged MDF file with the help of SysTools SQL Recovery. The process of restoration is simple and straight forward. Just follow the steps mentioned below and get your task done.

  • Select the Advance Scan option. Also, add the SQL Server version. If you do not know the version of the SQL MDF file, then it has an option to Auto-detect the version. Click on OK.

  • The application will scan the MDF file to fix all the corruption issues and show the scanning report.

  • You can preview any item of the master database by clicking on the tree structure of the left panel and clicking the Export button.

  • Choose Export as an option, whether you want to export as SQL Server Database or as SQL .csv scipt.

  • Enter SQL Server credentials like its server name, username, and password, and select the destination database in which you want to export your recovered database objects.

  • Select the With Schema & Data option and click the Export button, and the restoration of the master database of SQL Server will be done effortlessly.

  • You can visit the SQL Server and locate the restored database there.

Conclusion

Various reasons can lead you to restore the SQL Server master database. While the manual approach is fine, if you have a backup, the software will let you restore the master database without backup. Choose the solution based on your demand and restore without any trouble.

Introduction to Structured Query Language SQL pdf

SQL stands for Structured Query Language. SQL is a scripting language expected to store, control, and inquiry information put away in social databases. The main manifestation of SQL showed up in 1974, when a gathering in IBM built up the principal model of a social database. The primary business social database was discharged by Relational Software later turning out to be Oracle.

Models for SQL exist. In any case, the SQL that can be utilized on every last one of the major RDBMS today is in various flavors. This is because of two reasons:

1. The SQL order standard is genuinely intricate, and it isn’t handy to actualize the whole standard.

2. Every database seller needs an approach to separate its item from others.

Right now, contrasts are noted where fitting.

System Databases in SQL Server

Introduction

In SSMS, we many of may noticed System Databases under the Database Folder. But how many of us knows its purpose?. In this article lets discuss about the System Databases in SQL Server.

System Database

Fig. 1 System Databases

There are five system databases, these databases are created while installing SQL Server.

  • Master
  • Model
  • MSDB
  • Tempdb
  • Resource
Master
  • This database contains all the System level Information in SQL Server. The Information in form of Meta data.
  • Because of this master database, we are able to access the SQL Server (On premise SQL Server)
Model
  • This database is used as a template for new databases.
  • Whenever a new database is created, initially a copy of model database is what created as new database.
MSDB
  • This database is where a service called SQL Server Agent stores its data.
  • SQL server Agent is in charge of automation, which includes entities such as jobs, schedules, and alerts.
TempDB
  • The Tempdb is where SQL Server stores temporary data such as work tables, sort space, row versioning information and etc.
  • User can create their own version of temporary tables and those are stored in Tempdb.
  • But this database is destroyed and recreated every time when we restart the instance of SQL Server.
Resource
  • The resource database is a hidden, read only database that holds the definitions of all system objects.
  • When we query system object in a database, they appear to reside in the sys schema of the local database, but in actually their definitions reside in the resource db.

Restoring the SQL Server Master Database

INTRODUCTION

The master database contains records of the structure/configuration for both the current instance and all other databases. When you run sp_configure, you are writing data to the master database. It also contains most of the dynamic management views that are necessary to monitor the instance.

The importance of the master database is crucial. First, it has the information necessary for opening all other databases and has to be opened first. Then, it involves all instance level principals for the current instance.

It is crucial to back up the master database daily. Equally important is to know how to restore the master database to the instance. The most frequent cases are the database crash or the necessity to restore the master database to another instance when no longer use the source instance. In this article, we will examine the specific case of moving the master database to another instance.

CHECK THE STATUS OF APPLICATION SERVICES

Restoring the master database to another instance will involve starting the instance in the single user mode. Thus, it is essential to make sure that the active session is the only one controlling the instance.

For that, stop all application services from accessing the instance, especially if such applications have privileged access. Problems can occur if you start the instance in the single-user mode while the application has already established a session. In this case, you will not be able to proceed with an interactive session from SQL Server Management Studio.

STOP SQL SERVER SERVICES

Stop all SQL Server Services with the SQL Server Configuration Manager: right-click each service and select Stop from the context menu (see fig. 2).

Figure 1. Stopping SQL Services

START SQL SERVER IN THE SINGLE USER MODE

To restore the master database, you need the SQL Server instance in the single user mode. Take the following steps:

  1. Open CMD Prompt
  2. Navigate to C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Binn
  3. Issue sqlservr –m OR NET start MSSQLServer /c /m /T3604

Figure 2. Starting SQL Server in Single user Mode

OR

Figure 3. Starting SQL Server in Single user Mode

Note that step 2 refers to the Binn directory location. It can be different in your installation.

You can find the necessary directory by checking the Service tab of SQL Server service properties in SQL Server Configuration Manager (See Figure 4):
