Lindorm supports full and incremental backups for wide table data. Backups are stored in Alibaba Cloud Object Storage Service (OSS) and do not consume storage space in your Lindorm instance. After you enable backup and recovery, the system automatically performs incremental backups with no additional configuration. For full backups, configure a backup cycle and scope in the console.
Prerequisites
Before you begin, ensure that you have:
Backup and recovery enabled for your Lindorm instance. For details, see Enable backup and restoration.
Billing
Backup storage is billed on a pay-as-you-go basis:
Regions in China: USD 0.01857/GB/month
Asia-Pacific, Europe, and Americas: USD 0.02105/GB/month
Configure full backup
A full backup captures all data in the selected tables or namespaces at a point in time. The backup cycle determines your recovery point objective (RPO): a shorter cycle means less potential data loss, but each backup takes more time to complete. A longer cycle reduces backup frequency but increases how far back you may need to restore from.
Log on to the Lindorm console.
In the upper-left corner, select the region where your instance is deployed.
On the Instances page, click the instance ID or click View Instance Details in the Actions column.
In the left navigation pane, click Wide Table Engine.
Click the Backup & Recovery tab.
In the Full Backup section, click Create.
In the Create dialog box, configure the following parameters:
Parameter Description Tables for Backup Scope of the backup. Use an asterisk ( *) to back up all database data. To back up specific tables, use the formatnamespace:prefix—for example,default:testbacks up all tables in thedefaultnamespace whose names start withtest.Full Backup Cycle (Days) How often a full backup runs. Default: every 7 days. Valid range: 3–10 days. A shorter cycle reduces your RPO but requires more time per backup. A longer cycle reduces backup frequency but increases the time needed to restore. Perform Next Full Backup At The start time of the next full backup. Schedule backups during off-peak hours to minimize impact on your workload. Full Backup Reserved The number of full backup records to keep. Valid range: 3–12. Click OK.
Incremental backup
After you enable backup and recovery, Lindorm automatically backs up data that has changed since the last backup job. No additional configuration is required.
To monitor the current backup status, go to the Backup & Recovery tab and check the Incremental Backup section.
