<p>This article describes how to back up and restore.</p> <p><strong><span style="font-size:18px">Prerequisites</span></strong></p> <p>There is backup data. For more information about automatic backup, see <a href="http://pinganyun.com/ssr/help/database/mongodb/Manual.Backup_and_Restore.Automated_Backup" target="_blank">Automatic Backup</a>. For more information about manual backup, see <a href="http://pinganyun.com/ssr/help/database/mongodb/Manual.Backup_and_Restore.Manual_Backup" target="_blank">Manual Backup</a>.</p> <p><strong><span style="font-size:18px">Usage Guidelines</span></strong></p> <p>1. The data is restored in the new temporary recovery instance in Ping An Cloud DDS.</p> <p>&nbsp; &nbsp; &bull; The region where the new temporary recovery instance is located is the same as that of general instance. Extra fees will not be charged.</p> <p>&nbsp; &nbsp; &bull; A maximum of seven days of new DDS instance can be kept. After seven days, Ping An Cloud will release temporary recovery instance.</p> <p>2. The computing specification of new temporary recovery instance is the smallest. The storage specification is the same as that of the general instance in performing the restoration.</p> <p>3. After a temporary recovery instance is created successfully, computing specification and storage specification will not be changed.</p> <p>4. Each general instance creates a maximum of three temporary recovery instances everyday. If you need to restore the fourth temporary recovery instance, release temporary recovery instance you created before.</p> <p>5. Temporary recovery instances will automatically create a user. The username is temp_root and has read/write permissions.</p> <p><strong><span style="font-size:18px">Procedures</span></strong></p> <p>1. Log in to <a href="http://pinganyun.com/console/mongodb/overview" target="_blank">DDS Management Console</a>.</p> <p>2. In the left navigation pane, click <strong>DDS Cluster</strong> to enter the <strong>DBPaaS for DDS</strong> page.</p> <p>3. Select the target region.</p> <p>4. Click <strong>Manage</strong> in the <strong>Operations</strong> column of the target instance, and select the <strong>Backup </strong>page.</p> <p>5. On the <strong>Information</strong> tab, click <strong>Restore</strong> in the <strong>Operations</strong> column of the target backup to enter the <strong>Restore backup</strong> page.</p> <p>6. Restore backup according to the following information.</p> <table border="1" cellpadding="0" cellspacing="0"> <tbody> <tr> <td style="background-color:#ededed; vertical-align:top; width:137px"> <p><strong>Configuration item</strong></p> </td> <td style="background-color:#ededed; vertical-align:top; width:647px"> <p><strong>Description</strong></p> </td> </tr> <tr> <td style="vertical-align:top; width:137px"> <p>Method for Restoring</p> </td> <td style="vertical-align:top; width:647px"> <p>Backup data supports the restoring method of <strong>By backup set</strong> and <strong>Bytime:</strong></p> <p>&bull; <strong>By backup set:</strong> You can restore database information at backup time.</p> <p>&bull; <strong>By time:</strong> You can restore the database information from the first backup to any point in time between the first two hours of the current time.</p> <p>For example, you created a general instance at 00:00 on May 1, 2019 and current time is 12:00 on May 5, 2019.
