Database Backup (DBS) provides features such as single table restoration, geo-redundancy, full backup, incremental backup, and long-term archiving to back up and restore ApsaraDB for MongoDB (MongoDB) instances.

Features

Feature Description
SQL file backup DBS logically backs up data in the JSON format.
Backup data query DBS allows you to query backup data by using SQL statements without the need to restore data. For more information, see Query data in a single backup set.
Geo-redundancy DBS can back up a MongoDB instance to an Object Storage Service (OSS) bucket that is deployed in the destination region. DBS allows you to restore the backup data to a MongoDB instance in the source, the destination, or a different region.
Long-term archiving DBS can retain your backup data for up to ten years. After five years, DBS transfers the backup sets to Archive storage.
Fine-grained backup DBS allows you to back up a single table, a single database, multiple databases, or an entire MongoDB instance.
Backup speed limit DBS allows you to limit the backup speed to reduce the negative impact of backup operations on database performance.
Single-table restoration DBS allows you to restore a single table without the need to restore the entire MongoDB instance. This way, the restoration time is reduced.

Create a backup schedule

Create a backup schedule. For more information, see Purchase a backup schedule.
Note When you purchase a backup schedule, set the Database Type parameter to MongoDB and the Backup Method parameter to Logical Backup.

Configure the backup schedule

  1. Log on to the DBS console.
  2. In the left-side navigation pane, click Backup Schedules. On the Backup Schedules page, select a region in the upper-left corner.
  3. Find the ID of the backup schedule that you want to configure and click Configure Backup Schedule in the Actions column.
  4. In the Configure Backup Source and Destination step of the Configure Backup Schedule wizard, configure the backup source and destination, and click Next in the lower-right corner of the page.
    Section Parameter Description
    N/A Schedule Name The name of the backup schedule. DBS generates a backup schedule name. We recommend that you set a descriptive name that is easy to identify. Backup schedule names do not have to be unique.
    Backup Source Information Backup Mode The method used to back up data. Valid value: Logical Backup.
    Database Location The location of the database that you want to back up. Valid values:
    • User-Created Database with Public IP Address <IP Address:Port Number>
    • ECS-Hosted Database
    • ApsaraDB for MongoDB
    • Express Connect DB/VPN Gateway/Intelligent Gateway
    • No public network IP: Port's self-built database (accessed through the database gateway)
    Note
    • If you set the Database Location parameter to ApsaraDB for MongoDB, DBS automatically reads data from the secondary database to perform a full backup.
    • If you set the Database Location parameter to User-Created Database with Public IP Address <IP Address:Port Number> or Express Connect DB/VPN Gateway/Intelligent Gateway, you can specify whether to configure the connection address of the secondary database.
    Configuration of connection address of standby database Specifies whether to configure the connection address of the secondary database. If you select Yes for this parameter, DBS reads data from the secondary database to perform a full backup.
    Database Type The type of the database that you want to back up. By default, the database type that you select when you create the backup schedule is used.

    If you set the Database Location parameter to ApsaraDB for MongoDB, this parameter is not displayed.

    Instance Region The region where the instance that you want to back up resides.

    This parameter is displayed only when you set the Database Location parameter to ECS-Hosted Database, ApsaraDB for MongoDB, or No public network IP: Port's self-built database (accessed through the database gateway).

    Address The endpoint used to connect to the database that you want to back up.

    This parameter is displayed only when you set the Database Location parameter to User-Created Database with Public IP Address <IP Address:Port Number>, Express Connect DB/VPN Gateway/Intelligent Gateway, or No public network IP: Port's self-built database (accessed through the database gateway).

    Port Number The port used to connect to the database that you want to back up.

    This parameter is not displayed if you set the Database Location parameter to ApsaraDB for MongoDB.

    ECS Instance ID The ID of the Elastic Compute Service (ECS) instance where the database that you want to back up is deployed.

    This parameter is displayed only when you set the Database Location parameter to ECS-Hosted Database.

    MongoDB Instance ID The ID of the MongoDB instance that you want to back up. This parameter is displayed only when you set the Database Location parameter to ApsaraDB for MongoDB.

    This parameter is displayed only when you set the Database Location parameter to ApsaraDB for MongoDB.

    Peer VPC The virtual private cloud (VPC) where the database that you want to back up resides.

    This parameter is displayed only when you set the Database Location parameter to Express Connect DB/VPN Gateway/Intelligent Gateway.

    Gateway instance ID The ID of the database gateway.

    This parameter is displayed only when you set the Database Location parameter to No public network IP: Port's self-built database (accessed through the database gateway).

    Database Name The name of the database that you want to back up.
    Database Account The username of the account used to connect to the database that you want to back up.
    Password

    The password of the account that is used to connect to the database that you want to back up.

    After you enter the username and password of the database account, click Test Connection next to the password to check whether the information of the database that you want to back up is correct. If the specified parameters are valid, the Test Passed message appears. If the Test Failed message appears, click Check next to Test Failed. Modify the information about the instance that you want to back up based on the check results.

    Backup Destination Information Backup Storage Type The type of storage used to back up data. Valid values:
    • DBS Storage (recommended): Backup data is stored in DBS without requiring you to create storage space. You are charged based on the volume of your data that is stored in DBS. For more information about the billing method, see Storage fees.

      To reduce storage costs, we recommend that you use subscription storage plans. For more information, see Use storage plans.

    • OSS For User: You must create a bucket in the Object Storage Service (OSS) console in advance. For more information, see Create buckets.
    Note In this example, set this parameter to DBS Storage (recommended). If you set this parameter to OSS For User, you must set the OSS Bucket Name parameter.
    OSS Bucket Name

    This parameter is displayed only when you set the Backup Storage Type parameter to OSS For User.

    Storage Encryption The method used to encrypt the stored data. Valid values:
    • Encrypted (recommended): DBS uses AES-256, one of the advanced encryption standard ciphers, to encrypt the stored data.

      The server-side encryption feature is used in OSS. When you upload an object to a bucket for which server-side encryption is enabled, OSS encrypts and stores the object. When you download the encrypted object from OSS, OSS decrypts the object and returns the decrypted object to you. For more information, see Server-side encryption.

    • Non-encrypted: The backup data is not encrypted.
  5. In the Edit Backup Objects step, find the database or table that you want to back up and add it to the Selected section. Then, click Next.
    Note If you back up an entire database, the permission data and stored procedures are also backed up.
  6. In the Configure Backup Time step, set the parameters that are described in the following table and click Next in the lower-right corner of the page.
    Parameter Description
    Full-scale Backup Frequency

    The frequency of the backup schedule. Select Periodic Backup or Single Backup as needed.

    Note If you set this parameter to Periodic Backup, you must set the Full Data Backup Recurrence and Start At parameters.
    Full Data Backup Recurrence

    The days of the week on which DBS runs the backup schedule. Select at least one day of the week.

    Start At

    The start time of the backup, such as 01:00. We recommend that you set a time during off-peak hours.

    Note If a previous full data backup is not finished at the start time of the next backup, DBS skips the next backup.
    Real-Time Transaction Log Backup

    Specifies whether to enable incremental backup.

    This parameter is displayed only when you set the Full-scale Backup Frequency parameter to Periodic Backup.

    Maximum Concurrent Threads for Full Data Backup

    The maximum number of concurrent threads available for a full data backup. You can set this parameter to adjust the backup speed. For example, reduce the number of backup threads to minimize the impact on the database.

    The maximum number of actual concurrent threads varies based on backup schedule specifications. For more information, see How do I change the maximum backup speed?.

  7. In the Edit Lifecycle step, configure the lifecycle for full backup data in the Configure Full Data Backup Lifecycle section.
    If you set the Incremental real-time backup parameter to Enable in Step 6, you must configure the lifecycle for incremental backup data. For more information about the lifecycle rules of backup data, see How do I manage the lifecycle rules of backup sets?.
  8. After the configurations are complete, click Precheck in the lower-right corner of the page.
  9. If the Precheck Passed message appears, click Start Task.
    Note When the status of the backup schedule changes to Running, the backup schedule takes effect. You can view the backup task on the Backup Schedules page. For more information, see View backup schedules.
