Back up Tablestore data - Tablestore - Alibaba Cloud Documentation Center

To prevent business exceptions caused by accidental deletion or malicious tampering of important data, we recommend that you use the data backup feature of Tablestore to back up important data in your Tablestore instances. This topic describes how to regularly back up full or incremental Tablestore data by using the paid data backup feature of Tablestore.

Note

Cloud Backup provides a 30-day free trial for the data backup feature of Tablestore. During the free trial period, limits are imposed when you use the feature. You can switch to paid usage during the free trial based on your business requirements. For more information, see Usage notes of 30-day free trial.
For information about how to create a backup plan during the free trial period, see Back up data in Tablestore.

Usage notes

You can back up and restore only data tables and search indexes in Tablestore instances. You cannot back up secondary indexes or time series tables.
Cloud Backup
Cloud Backup cannot back up the encryption settings of encrypted tables in Tablestore. After encrypted tables in Tablestore are backed up to a backup vault, the tables are not encrypted in the backup vault.
We recommend that you back up Tablestore data during off-peak hours. If you want to back up data during peak hours, we recommend that you use the throttling feature to limit the maximum traffic that can be consumed by the data backup feature and prevent business interruptions.
Data is compressed during backup. The compression ratio varies based on the data features.
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 in which the resources that you want to back up reside.
  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 obtain Tablestore instances within 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 instance that you want to manage and click Back Up in the Actions column.
Select the resources that you want to back up.
1. In the Backup Content step of the Create Backup Plan panel, select the tables that you want to back up.
  You can select multiple tables to back up the tables at the same time.
2. Click Next.

Configure the backup settings.

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

If you did not create a backup policy, 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 name of the backup policy. The system automatically generates a name for a backup policy. You can also specify a custom name.
	Schedule	The execution plan of the backup policy. You can specify the backup frequency, first execution time, backup interval, and whether to use incremental backup.
	Lifecycle	The lifecycle of the backup data. You can specify custom and special retention periods for the backup data. You can also specify whether to retain at least one backup version.
Backup Data Management	Backup Vault	The backup vault in which data is stored. You can create a backup vault or select an existing backup vault.
	Replication Policy	Specifies whether to enable cross-region replication for the backup data. By default, cross-region replication for backup data is disabled. To back up Tablestore data across regions, turn on Replication to Other Region and select a destination region. Note You can also create a remote mirror vault for the backup vault that stores Tablestore data to automatically replicate the data for geo-redundancy. For more information, see Cross-region backup.
	Data Security	The security features for the backup data, including immutable backup and backup point virus detection. By default, the features are disabled. You can enable or disable the features based on your business requirements.

Configure throttling.
By default, throttling is disabled for data backup. If you want 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 backup operation. On the Backup Jobs tab, you can view the status of a backup job. If the value in the Status column of a backup job changes to Completed, the backup job is complete. After an incremental backup job is complete, the progress of the backup job is displayed as 100% in the Status column.

Manually execute a backup plan

On the Backup Plans tab, you can view the backup plan. If the specified backup start time does not arrive, you can manually perform a backup.

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.
