Database Backup (DBS) allows you to perform disaster recovery drills to restore databases on a regular basis. You can perform disaster recovery drills to verify whether the backup data is correct and the disaster recovery system is reliable.
Background information
If a disaster occurs, data recovery may fail due to operation errors that occur during the recovery process or invalid backups of the source data. To avoid disaster recovery failures, we recommend that you perform disaster recovery drills on a periodic basis to ensure that your disaster recovery system remains effective.
To perform traditional disaster recovery drills, you must deploy a large number of additional server devices. However, DBS allows you to perform disaster recovery drills without the need to purchase and deploy additional machine devices. Integrated with Copy Data Management (CDM), DBS allows you to create a database sandbox instance from your backup data. Then, your backup data can be validated, and a disaster recovery drill report is generated. After the drill is complete, DBS deletes the sandbox instance to reduce costs and ensure convenient recovery drills.
Billing
The disaster recovery drill feature is free of charge.
