Backup Types

Updated on 2025-02-12 GMT+08:00

Based on different dimensions, there are the following backup types in TaurusDB.

  • Full backups and incremental backups based on data volume
    Table 1 Comparison between full backups and incremental backups

    Backup Type

    Full backups

    Incremental backups

    Description

    All data in your DB instance is backed up.

    Only data that has changed within a certain period is backed up.

    Enabled by Default

    Yes

    Yes

    Retention Period

    Full backups are retained till the retention period expires.

    Incremental backups are retained till the retention period expires.

    Characteristic

    • A full backup is to back up all data of your DB instance in the current point of time.
    • You can use a full backup to restore the complete data generated when the backup was created.
    • Full backups include automated backups and manual backups.
    • The system automatically backs up data modifications made after the most recent automated or incremental backup every 5 minutes or when a certain amount of incremental data is generated.
    • Incremental backups are automated backups.
    • Incremental backups are created based on the most recent full backup, as shown in Figure 1, so the most recent full backup that exceeds the retention period is still retained. For details, see the following example.
      Figure 1 Incremental data restoration

    How to View

    Click the instance name. On the Backups page, click the Full Backups tab and view the backup size.

    Click the instance name. On the Backups page, click the Incremental Backups tab and view the backup size.

  • Automated backups and manual backups based on backup methods
    Table 2 Comparison between automated backups and manual backups

    Backup Type

    Automated backups

    Manual backups

    Description

    • You can set an automated backup policy on the management console, and the system will automatically back up your instance data based on the time window and backup cycle you set in the backup policy and will store the data for the retention period you specified.
    • Automated backups cannot be manually deleted. To delete them, you adjust the retention period specified in your backup policy. Retained backups (including full and incremental backups) will be automatically deleted at the end of the retention period.
    • Manual backups are user-initiated full backups of your DB instance. They are retained until you delete them manually.
    • Regularly backing up your DB instance is recommended, so if your DB instance becomes faulty or data is corrupted, you can restore it using backups.

    Enabled by Default

    Yes

    Yes

    Retention Period

    Automated backups are retained for the retention period you specified.

    The backup retention period ranges from 1 to 732 days.

    Manual backups are always retained until you delete them manually.

    Configuration

    Configuring a Same-Region Backup Policy

    Creating a Manual Backup

  • Same-region backups and cross-region backups based on backup regions
    NOTE:

    To configure a cross-region backup policy, submit a request by choosing Service Tickets > Create Service Ticket in the upper right corner of the management console.

    Table 3 Comparison between same-region backups and cross-region backups

    Backup Type

    Same-region backups

    Cross-region backups

    Description

    Backups are stored in the same region as your DB instance.

    Backups are stored in a different region from that of your DB instance.

    Enabled by Default

    Yes

    No

    Retention Period

    Same-region backups are retained for the retention period you specified.

    The backup retention period ranges from 1 to 732 days.

    NOTE:

    You can request to extend the retention period to 3,660 days by choosing Service Tickets > Create Service Ticket in the upper right corner of the management console.

    Cross-region backups are retained for the retention period you specified.

    The backup retention period ranges from 1 to 1,825 days.

    Characteristic

    Backups are stored in the same region as your DB instance. Same-region backup (automated backup) is enabled by default and cannot be disabled.

    Backups are stored in a region different from the region where your DB instance is located. After you enable cross-region backup, the backups are automatically stored in the region you specify.

    Configuration

    Configuring a Same-Region Backup Policy

    Configuring a Cross-Region Backup Policy

    How to View

    • If cross-region backup is enabled:

      Click Backups in the navigation pane. On the Same-Region Backups tab, view the backup size.

    • If cross-region backup is not enabled:

      Click Backups in the navigation pane and view the backup size.

    Click Backups in the navigation pane. On the Cross-Region Backups tab, locate a DB instance and click View Cross-Region Backup in the Operation column.
