    ApsaraDB for MongoDB:View backup storage capacity

    Last Updated:Mar 28, 2026

    ApsaraDB for MongoDB tracks backup storage separately from instance storage. Backup storage is the combined size of all full backup and log backup files. Each instance includes a free quota — storage beyond that quota is billed on a pay-as-you-go basis.

    Billing

    The free quota depends on your instance's disk type:

    Disk typeFree quota
    Cloud disk200% of instance storage capacity
    Local disk50% of instance storage capacity

    Storage that exceeds the free quota is charged on a pay-as-you-go basis. For pricing details, see the Pricing tab of the ApsaraDB for MongoDB buy page.

    Example: An instance with 100 GB of cloud disk storage has a free backup quota of 200 GB. If the total size of full backup and log backup files reaches 250 GB, you are billed for the 50 GB overage.

    View backup storage in the console

    1. Go to the Replica Set Instances or Sharded Cluster Instances page. In the top navigation bar, select the region where the instance resides. Find the instance and click its ID.

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

    3. In the upper-left corner of the backup list, check the Backup Storage details — used storage and free quota are both shown there.

    Note

    For standalone or replica set instances, you can also find backup storage details in the Backup Storage field under the Specification Information section on the Basic Information page. This field shows the storage used by full backup and log backup files, along with the free quota.
