Data restore

Restoring data requires you to drop all tables in the storage group. Be cautious when selecting your configurations. |
To restore data from a backup
- From the navigation bar, go to Data and select the Storage Group you want to restore data for.
- In the Storage Group row, click Actions > Restore.
The Restore Storage Group Configuration dialog loads.
- Complete the following fields:
Field name
Description
Select Backup
Select the backup type you used.
If the data is from an external system, select Custom.
HDFS URL
Defines the location of the backup.
If the URL is configured to an external HDFS cluster, all of its hosts must be accessible by of the hosts of the Security Event Manager.
Backup Timestamp
This config can be used to limit the data that you want to restore. It only applies for multi-backups (multiple incremental backups).
The following figure shows how multi-backups are restored:
Enable Safe Mode
By default, the normal backup job processes multiple tables in parallel and ignore any intermediate errors. Enable Safe Mode to back up the Storage Group tables sequentially and to fail early if any error occurs.
This mode may take longer to complete the back up, so only enable Safe Mode when the normal backup job fails.
Restore Timeout
Enter the number of hours before the restore job times out. After the hours elapse, the job will abort.
Advanced Config
These configurations define the resources used for the job. Normal users should keep the default configurations.
