If any system database fails or becomes corrupt, the SQL Instance becomes unavailable. It is important to protect these databases, however unlike a user database that handles real-time customer transactions, it is not necessary to perform backups on an hourly basis.</p> <h3 data-id="resolution">Resolution<a name="_GoBack" id="_GoBack"></a> </h3> <p>You can protect SQL data using the Unitrends Windows agent or, for VMware environments, you can run application-aware vProtect backups. If you have a VMware environment, see <a rel="nofollow" href="/home/leaving?allowTrusted=1&target=http%3A%2F%2Fwww.unitrends.com%2Fdocuments%2Flegacy-rs-ueb-admin-guide%2Fdefault.htm%23cshid%3D1562">Best practices for protecting VMware virtual machines</a> for a comparison of agent versus agentless SQL backps.</p> <h4 data-id="application-aware-vprotect-backups">Application-aware vProtect backups</h4> <p> If you are running application-aware vProtect backups, change the database recovery model to SIMPLE for proper transaction log truncation. If you do not use the SIMPLE recovery model, the transaction log continues to grow. </p> <h4 data-id="windows-agent-backups">Windows agent backups</h4> <p>If you are running backups with the Unitrends Windows agent, follow these recommendations.</p> --Create one schedule for master, model, and msdb databases and run a full backup weekly.<br>--Back up <b><i>all system databases</i></b> before and after each of the following: <ul><li>installing a server or SQL service pack</li> <li>installing hot fixes</li> <li>performing a cumulative update,</li> <li>performing login changes</li> <li>performing job changes</li> <li>performing operator changes</li> <li>performing database configuration changes</li> <li>performing SSIS package changes</li> <li>Changing replication settings </li> </ul> --Perform an on-demand full backup of the <b><i>master</i></b> database in these cases: <ul><li>After creating user databases</li> <li>After modifying SQL Instance configuration values</li> <li>After modifying SQL logins and credentials</li> <li>After making any change to the <i><b>master</b></i> database</li> </ul><p>--Recommendations for other databases</p> <ul><li> The <b><i>Distribution</i></b> database is available when replication is configured and the server is acting as a distributor. In the case of transactional replication, it is advisable to schedule full backup weekly, differentials daily and regular transactional log backups at least every 4 hours.</li> <li> The <b><i>Resource</i></b> database is a read-only, hidden database that contains all the system objects included in the SQL server. Perform a selective file-based backup of <i>mssqlsystemresource.mdf</i> and <i>mssqlsystemresource.ldf</i> found in the following locations: </li> </ul><p><b> </b>In case of SQL Server 2005: <b>..<i>.\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data</i></b></p> <p> In SQL Server 2008<b>: ...</b><b><i>\Program Files\Microsoft SQL Server\MSSQL10.\MSSQL\Binn\</i></b> </p> <ul><li>The <b>Tempdb</b> database is recreated each time the SQL Instance is started. Backup of <b>Tempdb</b> is not required.</li></ul><h3 data-id="article-link">Article link</h3> <p><a rel="nofollow" href="/home/leaving?allowTrusted=1&target=https%3A%2F%2Fdocs.microsoft.com%2Fen-us%2Fsql%2Frelational-databases%2Fbackup-restore%2Fback-up-and-restore-of-system-databases-sql-server">https://docs.microsoft.com/en-us/sql/relational-databases/backup-restore/back-up-and-restore-of-system-databases-sql-server</a></p> </article> </main>
