</div>
<div class="section" id="cbr_01_0012__section1366442772317"><h4 class="sectiontitle">Backup</h4><p id="cbr_01_0012__p56401103193123">A backup is a copy of a particular chunk of data and is usually stored elsewhere so that it may be used to restore the original data in the event of data loss. It can be generated either manually by a one-off backup task or automatically by a periodic task.</p>
<p id="cbr_01_0012__p19781134618171">CBR supports one-off backup and periodic backup. A one-off backup task is manually created by users and is executed only once. Periodic backup tasks are automatically executed based on a user-defined backup policy.</p>

A retention rule specifies for how long backups are retained or the number of backups that are retained. Automatic backups can be performed by applying a backup policy to a backup vault.</p>
</div>
<div class="section" id="cbr_01_0012__section18991157174711"><h4 class="sectiontitle">Instant Restore</h4><p id="cbr_01_0012__p518101811474">Instant Restore is a function for restoring data and creating images from backups. Instant Restore is much faster than a normal restoration process.</p>
<p id="cbr_01_0012__p141820186479">Common backups do not support Instant Restore, whereas, enhanced backups do. By default, all CBR backups are enhanced backups. Compared with common backups, enhanced backups use less time to restore server data or create images.</p>
</div>
<div class="section" id="cbr_01_0012__section0356152211250"><h4 class="sectiontitle">Enhanced Backup</h4><p id="cbr_01_0012__p16214654142310">Enhanced backups can be used to quickly restore server data or create images. This type of backups depends on Instant Restore.</p>
<p id="cbr_01_0012__p1921485462317">Before Instant Restore is rolled out, all CBR backups generated are common backups. After Instant Restore is rolled out, all CBR backups generated are enhanced backups. This is an overall performance upgrade of CBR, and no additional configuration is required. Currently, all CBR backups generated are enhanced backups.</p>
<p id="cbr_01_0012__p19214155412230">It takes a longer time to restore server data or create images using common backups. Enhanced backups can do the same thing with significantly shortened time. The only difference between common backups and enhanced backups is the restoration speed.</p>

<h1 class="topictitle1">(Optional) Migrating Resources from CSBS/VBS</h1>
<div id="body1576221026075"><div class="section" id="cbr_03_0104__section10166104811512"><h4 class="sectiontitle">Context</h4><p id="cbr_03_0104__p448612538153">The cloud platform has launched the next-generation backup service, CBR. If you have backup resources in CSBS or VBS but want to switch to CBR for the management of these historical backup resources, you can migrate them to CBR in a few clicks.</p>
<p id="cbr_03_0104__p16731121343015">If you have never used CSBS or VBS, or do not need the historical backups anymore, skip this section.</p>
</div>
<div class="section" id="cbr_03_0104__section136611613205217"><h4 class="sectiontitle">Migration Rules</h4><p id="cbr_03_0104__p88591119576">During migration, the system will automatically create vaults based on your historical resources.</p>
<ol id="cbr_03_0104__ol1238972010129"><li id="cbr_03_0104__li73891020201219">If servers or disks have been associated with a backup policy and have been backed up, during the migration, the system will create a vault with the same name (up to 64 characters) as the policy name, regardless of whether the policy is enabled. After the vault is created, the policy will be applied to the vault.</li><li id="cbr_03_0104__li183892020191218">If servers or disks have been associated with a backup policy but no backup has been generated, during the migration, the system will create a vault only when the policy is enabled. After the vault is created, the policy will be applied to the vault. The rule for naming the vault is the same as that in the preceding rule.</li><li id="cbr_03_0104__li9840334111616">If servers or disks have been applied with a backup or replication policy but no backup or replica has been generated, and the policy is not enabled, then only the policy will be migrated.</li><li id="cbr_03_0104__li181062816171">The system will migrate backup and replication policies regardless of whether they are associated with servers or disks.</li><li id="cbr_03_0104__li49591425191519">Generated backup replicas will be stored in a replication vault named <strong id="cbr_03_0104__b0880144017815">default</strong>.</li><li id="cbr_03_0104__li23893202125">Other backups, such as manual backups, will be stored in a server backup vault named <strong id="cbr_03_0104__b648164796">default</strong>. Different vaults will be automatically created based on different types of resources. For example, the system will create a disk backup vault during the migration of disk backups.</li><li id="cbr_03_0104__li1666418206431">After resources are migrated, backups created using CBR will also be displayed in VBS Console, but you will be billed only once.<div class="note" id="cbr_03_0104__note17345637174813"><img src="public_sys-resources/note_3.0-en-us.png"><span class="notetitle"> </span><div class="notebody"><p id="cbr_03_0104__p14345113724810">To delete backups from VBS Console, find these backups in CBR and delete them. Then, the backups will also be automatically deleted from VBS Console.</p>
</div></div>
</li><li id="cbr_03_0104__li938512338425">If an image has been created using a backup before the migration and a tag has been added to the image, the backup migration may fail. In this case, go to IMS Console, delete the tag of the image, and then perform the migration again. After the migration is complete, re-add the tag if needed.</li></ol>
<p id="cbr_03_0104__p7403131111403">Base on the preceding rules, the capacity of each vault created by the system is predefined as 1.2 times of the total backup size.</p>
<p id="cbr_03_0104__p2269155201515">For example, a user has a 100 GB ECS and a 50 GB ECS. The used storage capacity of the two ECSs is 20 GB and 10 GB, respectively. The user manually has backed up the two entire ECSs using cloud server backup. During migration, the capacity of the vault automatically created will be 1.2 times of the total backup size. In this example, the total backup size multiplied by 1.2 is 36 GB. So the system will automatically create a 36 GB vault.</p>
</div>
<div class="section" id="cbr_03_0104__section1520702113119"><h4 class="sectiontitle">Constraints</h4><ul id="cbr_03_0104__ul2052518413015"><li id="cbr_03_0104__li4525141605">The vaults you have cannot be used for migration. The system will automatically migrate resources to the vaults created by the system.</li><li id="cbr_03_0104__li147241533154518">Backup resources of one account need to be migrated only once.</li><li id="cbr_03_0104__li8776155774512">After resources are migrated, disk backups and server backups will be automatically stored in CBR vaults. No further operations are required.</li></ul>
