Back up Tablestore data - Tablestore - Alibaba Cloud Documentation Center

Back up important data in your Tablestore instances to prevent data loss from accidental deletion or malicious tampering. Schedule regular full or incremental backups of Tablestore data by using the paid data backup feature.

Note

Cloud Backup provides a 30-day free trial for the Tablestore data backup feature. Usage limits apply during the free trial. Switch to paid usage at any time. For more information, see Usage notes of 30-day free trial.
To create a backup plan during the free trial, see Back up data in Tablestore.

Usage notes

Back up and restore only data tables and search indexes in Tablestore instances. Secondary indexes and time series tables are not supported.
Disabled VCU (formerly reserved mode) instances do not support data backup and restoration. Cloud Backup retains previously backed-up data in the backup vault of the corresponding region.
Cloud Backup does not back up the encryption settings of encrypted tables in Tablestore. Encrypted tables lose their encryption after being backed up to a backup vault.
Back up Tablestore data during off-peak hours. To back up data during peak hours, use the throttling feature to limit the maximum traffic consumed by data backup and prevent business interruptions.
Data is compressed during backup. The compression ratio varies based on data characteristics.
The automatic archiving feature in the backup policy does not apply to Tablestore backup.
Cloud Backup automatically creates a tunnel in Tablestore for each backup job to back up data.

Procedure

Create a backup plan

Go to the Create Backup Plan panel.
1. On the Data Backup page in the Tablestore console, select the region of the resources to back up.
  Cloud Backup automatically reads and loads the Tablestore instances in the region.
  Note
  The first time you use the data backup feature, Cloud Backup automatically creates a service-linked role named AliyunServiceRoleForHbrOtsBackup to access Tablestore instances in your Alibaba Cloud account. Follow the on-screen instructions to authorize Cloud Backup to access your Tablestore resources. For more information, see Service-linked roles for Cloud Backup.
2. Find the target instance and click Back Up in the Actions column.
Select resources to back up.
1. In the Backup Content step of the Create Backup Plan panel, select the tables to back up.
  Select multiple tables to back them up simultaneously.
2. Click Next.

Configure the backup settings.

In the Backup Config step of the Create Backup Plan panel, select a backup policy.

If no backup policy exists, click Create Backup Policy. In the Create Backup Policy dialog box, configure the parameters and click OK.

Note

For more information about the parameters in a backup policy, see Manage backup policies.

Section	Parameter	Description
Basic Settings	Policy Name	The backup policy name. The system generates a default name. Specify a custom name as needed.
	Schedule	The backup policy schedule. Specify the backup frequency, first execution time, backup interval, and whether to use incremental backup.
	Lifecycle	The backup data lifecycle. Specify custom and special retention periods. Optionally, retain at least one backup version.
Backup Data Management	Backup Vault	The backup vault for storing data. Create a new vault or select an existing one.
	Replication Policy	Controls cross-region replication for backup data. Cross-region replication is disabled by default. To back up Tablestore data across regions, turn on Replication to Other Region and select a destination region. Note Alternatively, create a remote mirror vault to automatically replicate Tablestore backup data for geo-redundancy. For more information, see Cross-region backup.
	Data Security	Security features for backup data, including immutable backup and backup point virus detection. Disabled by default. Enable as needed.

Configure backup policy

Configure throttling.
Throttling is disabled by default. To back up data during peak hours, turn on Enable Bandwidth Throttling and specify the throttling period and maximum traffic.

Click OK.
By default, a backup plan is enabled. Cloud Backup backs up Tablestore data based on the specified backup policy.
Cloud Backup generates a backup job for each operation. View backup job status on the Backup Jobs tab. When the Status column shows Completed, the backup is finished. For incremental backups, the Status column also shows 100% progress.

Manually execute a backup plan

The Backup Plans tab lists all backup plans. To run a backup before the scheduled start time, manually trigger one:

Full backup: In the Actions column of the backup plan, choose More > Perform Full Backup Now.
Incremental backup: If an incremental backup interval is specified for Tablestore data in the backup policy, choose More > Perform Incremental Backup Now in the Actions column of the backup plan.

Manually execute backup
