Original: SQL Server system database backup best Practices

First understand the main system databases:

System Database
Master Contains core information for login information and other databases
msdb Store jobs, operators, alerts, backup restore history. Database Mail information, and so on.
Model For all new database models, if you want the new database to have some objects, you can create them here.
Tempdb Rebuild when SQL Server restarts, so no backup required

In addition to the above four kinds, there is actually a database:Resource

Introduced from 2005, a read-only, hidden database that contains all of the system objects in SQL Server. The resource database is restored because SQL Server does not support backup. So the DBA needs to replicate resource's mssqlsystemresource.mdf and mssqlsystemresource.ldf files.

The resource database in SQL Server 2005 is in the path: "<drive>:\program Files\Microsoft SQL Server\mssql.1\mssql\data\" location

The resource database in SQL Server 2008 is in the path: "<drive>:\program Files\Microsoft SQL Server\mssql10.<instance_name>\ Mssql\binn\ "location.

Reporting Services Database: If you have report services installed, you will see both service databases

ReportServer
ReportServerTempDB


Replication System Database (Replication Service systems databases)
Distribution-When the replication service is configured, you will see this database.



If you need to perform a file-based backup function to back up the resource database, you need to turn on xp_cmdshell

Use Mastergosp_configure ' Show advanced options ' go/* 0 = Disabled, 1 = Enabled */sp_configure ' xp_cmdshell ', 1GORECONFIGU RE with Overridego

Use the following statement to back up the system database to the E-drivesystemdatabasebackups In the folder:

Use Mastergoselect GETDATE () as ' System database backup Start time ' go/* backup distribution database */BACKUP DATABASE Di Stribution to DISK = ' E:\SystemDatabaseBackups\Distribution.BAK ' with initgo/* backup reportserver Database */Backup DATA BASE ReportServer to DISK = ' E:\SystemDatabaseBackups\ReportServer.BAK ' with initgo/* Backup reportservertempdb Database */Backup DATABASE reportservertempdb to DISK = ' E:\SystemDatabaseBackups\ReportServerTempDB.BAK ' with initgo/* BACKUP Ma  Ster model */backup DATABASE model to DISK = ' E:\SystemDatabaseBackups\Model.BAK ' with initgo/* BACKUP Master DATABASE */ Backup DATABASE Master to DISK = ' E:\SystemDatabaseBackups\Master.BAK ' with initgo/* backup Master MSDB */backup Databas E MSDB to DISK = ' E:\SystemDatabaseBackups\MSDB.
