<div id="body1552811973903"><p id="cbr_06_0003__p16762329134213">After an initial full backup, a server continues to be backed up incrementally by default.</p>
<div id="body1552811973903"><p id="cbr_06_0003__p16762329134213">By default, the initial backup performed for a resource is a full backup, and all subsequent backups are incremental backups. If a resource has been backed up for many times, and then all of its generated backups are deleted, and the resource is backed up again, the system will also perform a full backup for the resource.</p>
<ul id="cbr_06_0003__ul77961554201110"><li id="cbr_06_0003__li479505417112">The initial full backup covers only the used capacity of a disk.

If 5 GB data changed since the last backup, only the 5 GB changed data will be backed up.</li></ul>
<p id="cbr_06_0003__p82931212134314">CBR allows you to use any backup, no matter it is a full or incremental one, to restore the full data of a resource. By virtue of this, manual or automatic deletion of a backup will not affect the restoration function.</p>

<div id="body1552811973904"><p id="cbr_06_0007__p923917549213">No. You can back up servers that are in use. When a server is running, data is written onto disks on the server, and some newly generated data is stored in the server memory as cached data. During a backup task, the data in the memory will not be automatically written onto disks, resulting in data inconsistency between disks and their backups.</p>
<p id="cbr_06_0007__p12406146115219">To ensure data integrity, back up the server during off-peak hours when no write operation is performed on the disks. For applications that require strict consistency, such as databases and email systems, you are advised to enable application-consistent backup.</p>
