Application-Consistent Backup
Overview
There are three types of backups in terms of backup consistency:
- Inconsistent backup: An inconsistent backup contains data taken from different points in time. This typically occurs if changes are made to your files or disks during the backup. CBR cloud server backup uses the consistency snapshot technology for disks to protect data of ECSs and BMSs. If you back up multiple EVS disks separately, the backup time points of the EVS disks are different. As a result, the backup data of the EVS disks is inconsistent.
- Crash-consistent backup: A crash-consistent backup captures all data on disks at the time of the backup and does not capture data in memory or any pending I/O operations. Although it cannot ensure application consistency, disks are checked by chkdsk upon operating system restart to restore damaged data and undo logs are used by databases to keep data consistent.
- Application-consistent backup: An application-consistent backup captures data in memory or any pending I/O operations and allows applications to achieve a quiescent and consistent state.
Figure 1 compares these backup types in detail.
CBR supports both crash-consistent backup (also called cloud server backup) and application-consistent backup.
Crash-consistent backup does not back up data in memory or pending I/O operations and cannot be used to restore applications. If your server is running a MySQL or SAP HANA database, you can use application-consistent backup. An application-consistent backup capture application information both in memory and in pending I/O operations and can be used to quickly restore applications.
Differences Between Application-Consistent Backup and Cloud Server Backup

Recommended scenario |
Data of cloud servers and their databases such as MySQL or SAP HANA database needs to be backed up. All data and application configurations need to be restored in case of an error. |
Only data of cloud servers needs to be backed up. Such data needs to be restored in case of an error. If cloud server backup is used to back up database servers, some database configurations may fail to be restored from the backups and issues may occur when the database is restarted. |
There are two types of vaults to store server backups. Those store backups of non-database servers are server backup vaults, and those store backups of database servers are database server backup vaults.

For Windows servers, ensure that Volume Shadow Copy is installed and can run properly.
For databases that are not in the compatibility list, you can create a custom script to back up the database server by referring to Using a Custom Script to Implement Application-Consistent Backup in the Cloud Backup and Recovery Best Practices.
Process
Figure 2 shows the application-consistent backup process.
- Change the security group: Before performing an application-consistent backup task, change the security group of the server you want to back up.
- Install the agent: Change the security group and install the agent in any sequence. Ensure that the two operations are completed before backing up the desired server.
- Create an application-consistent backup: After creating a server backup vault for storing application-consistent backups, associate it with the desired database server and then create an application-consistent backup.
- Modify or compile a custom script: After backing up a database server on the CBR console, modify or compile a custom script on the database of the server. For details, see Using a Custom Script to Implement Application-Consistent Backup.
- Verify the backup result: After the backup is performed, verify that the backup succeeds. For details, see Verifying the Application-Consistent Backup Result.
- Use the backup to restore server data: Use the application-consistent backup to restore server data. The restored database applications and data are the same as those at the backup point in time. For details, see Restoring from a Cloud Server Backup.
