RES02-02 Automatically Backing Up Data
You can set a periodic backup policy to automatically back up data based on the RPO requirements of the data that needs to be backed up.
- Risk level
High
- Key strategies
Use Huawei Cloud backup services or third-party backup software to back up data, and set the automatic backup frequency based on the RPO requirements. Cloud Backup and Recovery (CBR) can be used to back up ECSs, BMSs, EVS disks, SFS Turbo file systems, and file directories. Most cloud services, such as RDS, DDS, and DCS, have native backup functions. KooGallery also provides various backup software to back up data.
Huawei Cloud supports workload data backup. Typical backups include:
- CBR backups: CBR provides snapshot-based backup and restore for disks (EVS disks) and servers (ECSs, Flexus instances, and BMSs), supports hybrid cloud backups, and can back up SFS Turbo file systems and databases (such as MySQL and SAP HANA) that are deployed on cloud servers. CBR supports one-off backup and periodic backup. Currently, the backup time can only be on the hour. You can select multiple hours for backup. The minimum RPO is 1 hour. You need to select a proper backup period based on the data importance.
- Automatic database backup: Database services, such as RDS, DDS, and GaussDB, support default automatic backup. Incremental backup is automatically performed for instances every 5 minutes to ensure database reliability.
- DCS backup: DCS provides automatic and manual backup functions for non-single-node instances. You are advised to set an automatic backup policy.
In addition, you can use third-party backup software to back up data.
In Huawei Cloud, data is backed up to OBS to ensure high security.
