MongoDB Backup

Last updated: 2022-07-12 15:14:50

    Overview

    MongoDB Backup is a SCF-based feature provided by COS. It allows you to back up data in TencentDB for MongoDB to COS so that data can be stored persistently and protected from data loss or corruption. After you set a backup function rule for a bucket, SCF will scan your MongoDB backup files periodically and store them in the bucket.

    Notes

    • MongoDB Backup functions only back up the backup files of TencentDB for MongoDB. Therefore, if MongoDB backup has not been enabled, the functions cannot be executed. For more information about TencentDB for MongoDB backups, see Data Backup.
    • If you have added a MongoDB backup rule to your bucket in the COS console, the backup function will appear in the SCF console. DO NOT delete this function. Otherwise, your rule may not take effect.
    • MongoDB Backup is supported in SCF-enabled regions, including Guangzhou, Shanghai, Beijing, Chengdu, Hong Kong (China), Singapore, Mumbai, Toronto, and Silicon Valley. For more supported regions, see SCF Documentation.

    Directions

    1. Log in to the COS console.
    2. On the left sidebar, click Application Integration > Data Backup and find MongoDB Backup.
    3. Click Configure Backup Rule to go to the rule configuration page.
    4. Click Add Function.
      Note:

      If you haven't activated SCF, go to the SCF console to activate it and authorize the service as instructed.

    5. In the pop-up window, configure the following items:
    • Function Name: Uniquely identifies a function and cannot be modified after being set. You can view the function in the SCF console.
    • Associated Bucket: A bucket to store the MongoDB backup files.
    • Trigger Period: Triggers the backup operation for the MongoDB Backup function. Every day, every week, and custom periods are supported.
    • Cron Expression: If you use a custom period, you can use Cron to specify the trigger period rule. Cron follows the local Standard Time. For detailed configuration policies, see Timer Trigger Description.
    • Database Instance: MongoDB instance in the region where the current bucket resides
    • Delivery Path: Delivery path prefix of the backups. If not specified, backups will be stored in the root directory of the bucket.
    • SCF Authorization: SCF needs to be authorized so that it can read the MongoDB instances as well as their backup files, and store the backup files to the specified bucket.
    1. Click Confirm.
      You can perform the following operations on the created function:
    • Click Log to view the historical running status of MongoDB backup. If an error is reported, you can click Log to quickly redirect to the SCF console for viewing the error log details.
    • Click More > Edit to modify the MongoDB data backup rule.
    • Click More > Delete to delete the unwanted MongoDB backup rule.
