Restore data within seconds

Last Updated: May 30, 2020

Database Backup (DBS) allows you to restore terabytes of data within 10 seconds based on technologies such as database physical backup and snapshot mounting. It can provide read and write capabilities and meet the requirements for data restoration after misoperations, recovery rehearsals, emergency disaster recovery, DevOps, and data analytics.

How it works

DBS allows you to restore data within seconds. You must create a physical backup schedule and enable second-level restoration in the DBS console. The system automatically obtains full data, and captures incremental data on a regular basis. The system then merges the full and incremental data and generates snapshots at specified points in time, such as every 10 minutes. You can select any of these snapshots for database restoration. 1

Procedure

1. Enable second-level restoration

Log on to the DBS console and click Backup Schedules in the left-side navigation pane. On the Backup Schedules page, click the backup schedule to go to the Configure Task page. In the Task Running Information section, click Set up second level recovery.

The second-level restoration task enters the Data preparing state.

2. Start a second-level restoration task

After the data has been prepared, a time range is displayed. Data within this time range will be restored through second-level restoration. Click Second level recovery database in the upper-right corner of the Configure Task page to start a second-level restoration task.
