Manage tags

Tags are key-value pairs that organize and manage storage vaults. Group vaults by purpose, owner, or other criteria to search and perform batch operations.

Set tags for a storage vault

Usage notes

  • Each tag consists of a key-value pair.

  • A tag key must be unique on a single resource.

    For example, the company:a tag has been added to a backup vault. If you add the company:b tag to the backup vault, the company:a tag is replaced by the company:b tag.

  • Tags are not shared across regions. For example, tags that are created in the China (Hangzhou) region are invisible to the China (Shanghai) region.

Configure vault features

Enable advanced features for data protection and compliance, including cross-region backup for disaster recovery, immutable backup, and immutable archive.

Configure cross-region backup

Create a mirror backup vault in another region for disaster recovery. Cloud Backup automatically replicates data from the source to the mirror vault. For more information, see Cross-region backup.

Important

Cross-region backup is not supported for archive vaults.

Enable immutable backup

Immutable backup prevents the backup vault and its backups from being modified or deleted during the retention period. For more information, see Immutable backup.

Important
  • Immutable backup is available only for backup vaults whose Storage Vault Type is General Backup. Once enabled, this feature cannot be disabled.

  • Enabling immutable backup does not affect normal backup and restore operations.

In the Actions column of the backup vault, click > Modify Backup Vault. In the dialog box, update the vault name and enable immutable backup.

Enable immutable archive

Immutable archive prevents the archive vault and its data from being modified or deleted during the retention period.

Important
  • Immutable archive is available only for archive vaults whose Storage Vault Type is Archive. Once enabled, this feature cannot be disabled.

  • Enabling immutable archive does not affect normal data archiving operations.

In the Actions column of the archive vault, click > Configure Archive Vault. In the dialog box, update the vault name and enable immutable archive.

Manage vault settings

Adjust vault settings such as alert notifications and data retention periods.

Configure alert settings

In the Actions column of the storage vault, click > Alert Settings to configure alerts. Cloud Backup emails your Alibaba Cloud account by default when a backup fails or a client disconnects.

  • Disabled: No alert notifications are sent.

  • Notify Alibaba Cloud Account: Send email notifications to your Alibaba Cloud account (default).

  • Custom: Select specific contacts or contact groups to receive alert notifications.

Set the retention period

Important
  • Available only when Storage Vault Type is Database Backup. Backup data is automatically deleted after the retention period expires.

  • For archive vaults, set the retention period only when creating an archive plan. It cannot be modified later.

In the Actions column of the database backup vault, click > Set Retention Period to set the retention period. Retain backup data for a specific duration or permanently.

  • Setting the retention period to 0 permanently retains backup data.

  • Changes apply to all existing backups and may take up to 24 hours to take effect.

  • Incremental, cumulative incremental, and log backups require a complete backup chain. The entire chain is retained until the last backup expires.

Configure RAM user permissions for storage vaults to delegate backup, restore, or archive operations without granting full account access.

Configure permissions for a backup vault

  1. In the Actions column of the backup vault, click > Modify Backup Vault.

  2. Grant a RAM user permissions for backup and restore operations on this vault.

  3. Click the image icon to copy the access policy template. Create a custom policy in the RAM console and attach it to the RAM user. For more information, see Create a custom policy.

Configure permissions for an archive vault

  1. In the Actions column of the archive vault, click > Configure Archive Vault.

  2. Grant a RAM user permissions for data archiving and retrieval on this vault.

  3. Click the image icon to copy the access policy template. Create a custom policy in the RAM console and attach it to the RAM user. For more information, see Create a custom policy.
