:Try Tablestore data backup for free

Usage notes

• The first time you use the data backup feature, Cloud Backup automatically creates a service-linked role named AliyunServiceRoleForHbrOtsBackup. This role is used to access the Tablestore instance resources in your account. Complete the authorization for Cloud Backup in the wizard. For more information, see Service-linked roles for Cloud Backup.

• Cloud Backup automatically discovers and loads Tablestore instances in the corresponding region. You do not need to install a client.

• You can back up Tablestore data only to a Cloud Backup backup vault in the same region. Cross-region backup is not supported.

• You can back up and restore only data tables and search indexes in Tablestore instances. Secondary indexes and time series tables are not supported.

• You cannot back up or restore data for reserved mode instances that are in a disabled state. Existing backups for these instances remain in the Cloud Backup backup vault in the corresponding region.

• When you back up an encrypted Tablestore table, Cloud Backup does not back up the encryption settings. Therefore, the table stored in the backup vault is not encrypted.

• Perform data backups during off-peak hours for Tablestore. If you must run a backup during peak hours, use the throttling feature to limit the maximum bandwidth the backup consumes to prevent any impact on your services.

• Data is compressed during backup. The compression ratio depends on the data characteristics.

Procedure

1. Go to the Create Backup Plan panel.

   1. Log on to the Tablestore console.

   2. In the left-side navigation pane, click Data Backup.

   3. On the Data Backup page, select the region where the instance is located.

      The system automatically retrieves the list of instances in the selected region.

   4. Find the target instance and click Back Up in the Actions column.

2. Select backup content.

   1. In the Backup Content step of the Create Backup Plan panel, enter a name for the backup plan and select the tables to back up.

      You can select multiple tables to back up at once.

   2. Click Next.

3. Configure the backup plan.

   1. In the Backup Plan step, configure the full backup parameters.

      Parameter	Description
      Full Backup	The Full Backup switch is enabled by default. This indicates that a full backup is performed. This switch cannot be disabled.
      Backup Frequency	The backup frequency. Supported frequencies are Daily, Weekly, and Monthly.
      Run At	The time of day to start the backup, accurate to the second.
      Time Interval	This parameter is required only when Backup Frequency is set to Daily. Specifies the interval in days between backups.
      Backup Week	This parameter is required only when Backup Frequency is set to Weekly. Specifies the day(s) of the week to perform the backup. You can select multiple days.
      Backup Month	This parameter is required only when Backup Frequency is set to Monthly. Specifies the month(s) to perform the backup. You can select multiple months.
      Backup Day	This parameter is required only when Backup Frequency is set to Monthly. Specifies the day(s) of the month to perform the backup. You can select multiple days. Important If a selected day does not exist in the specified month, Cloud Backup automatically skips the backup for that scheduled time.

   2. Configure incremental backup settings as needed.

      The Incremental Backup switch is enabled by default. An incremental backup captures only the data that has changed since the last full backup. This results in smaller backup sizes and faster completion times.

      • If you only need scheduled full backups, disable the Incremental Backup switch.

      • If you need to continuously back up incremental data in a table, keep the Incremental Backup switch enabled and configure the following parameters.

        Parameter	Description
        Backup Frequency	The backup frequency. Supported frequencies are Minutely, Hourly, and Daily.
        Run At	This parameter is required only when Backup Frequency is set to Daily. The time of day to start the backup, accurate to the second.
        Time Interval	The interval between backups. The valid range for this parameter varies based on the backup frequency. If Backup Frequency is set to Minutely, the interval is fixed at 30 minutes and cannot be changed. If Backup Frequency is set to Hourly, you can set the interval to a value from 1 to 24 hours. If Backup Frequency is set to Daily, you can set the interval to a value from 1 to 5 days.

   3. Click Next.

4. Configure backup options.

   1. Create a new backup vault or select an existing one as needed.

      New backup vault

      If you do not have a backup vault, or if the existing ones do not meet your needs, create a new one.

      1. Set Backup Vault to Create a backup vault.

         To maximize the redundancy of your backup data, Cloud Backup uses zone-redundant backup vaults by default in regions where they are supported. If a region supports only locally redundant backup vaults, Cloud Backup uses locally redundant backup vaults. You do not need to manually select the backup vault type.

      2. The system generates a default name for the backup vault, which you can change as needed.

      3. By default, a new backup vault is added to the default resource group (named default resource group). You can select a different existing resource group or create a new one.

         Note

         A resource group is a mechanism for managing resources by group under your Alibaba Cloud account. Resource groups help you simplify resource organization and authorization management for a single account. For more information about how to create a resource group, see Create a resource group.

      4. To encrypt the data in your backup vault at rest, configure an encryption method.

         Cloud Backup provides two encryption methods: Cloud Backup-managed and KMS. Configure this setting as needed.

         Important

         • The encryption method of a backup vault cannot be changed after creation.

         • If you use KMS for encryption, you cannot change the KMS key later.

         • After you use a KMS key for encryption, do not delete or disable the key. Otherwise, you cannot use the backup vault to back up or restore data.

         • To use a KMS key to encrypt data in a backup vault, you must first create a key in Key Management Service (KMS) and obtain its key ID. For more information, see Create a key.

         Encryption method	Actions	Description
         Cloud Backup-managed encryption	Set Vault Encryption Method to Cloud Backup-managed.	Cloud Backup uses a service-managed key to encrypt data in the backup vault and automatically decrypts it during restoration. The first time you use this method, Cloud Backup creates a service-managed KMS CMK in the KMS console. You only need to activate KMS to use this method. You do not need to purchase a KMS instance.
         KMS encryption	Set Vault Encryption Method to KMS. Select a KMS Key ID.	This method uses the specified KMS key ID to encrypt data in the backup vault. Cloud Backup encrypts data based on the key you create, giving you full control over the encryption key. When you use this method, you need to create a service-linked role AliyunServiceRoleForHbrVaultEncryption that grants the backup service permissions to access your KMS.

      Existing backup vault

      If you have an existing backup vault that meets your needs, select it.

      1. Set Backup Vault to Select Vault.

      2. Select a backup vault name.

   2. The default retention period for backup data is two years. You can change this value as needed.

      The minimum retention period is one day.

   3. If you plan to back up data during peak hours, turn on the Enable Bandwidth Throttling switch and configure the throttling parameters.

      By default, throttling is disabled, meaning no limit is placed on the backup traffic. Backing up data during peak hours without throttling may affect your services.

      1. Under Time Range (Hour), drag the start and end sliders to define a time window for throttling.

      2. Enter the maximum bandwidth for this time window and click Add.

         To add throttling rules for multiple time windows, repeat the preceding steps. After you set the rules, you can view the throttling information for different time windows in the Bandwidth Throttling Rules.

5. Click OK.

   After the backup plan is created, it is enabled by default. Cloud Backup starts the Tablestore backup tasks according to the specified start time and interval. You can view the created plan on the Backup Plan tab.

6. If you need to run an unscheduled backup, you can trigger one manually.

   • To immediately run a full backup, choose More > Perform Full Backup Now in the Actions column of the backup plan.

   • To immediately run an incremental backup, choose More > Perform Incremental Backup Now in the Actions column of the backup plan.

   Each time a backup operation runs, Cloud Backup generates a backup job. You can monitor these jobs on the Backup Jobs tab. The backup is complete when the value in the Status column changes to Completed. When an incremental backup is complete, its Status column also shows a progress of 100%.
