ApsaraDB for MongoDB allows you to create an instance based on a running time point of an existing instance. The data of the new instance is recovered from that of the existing instance at the selected time point. This method applies to data recovery or data verification scenarios.

Prerequisites

  • The existing instance must be a replica set or sharded cluster instance.
    Note Standalone instances do not support this feature.
  • Currently, you can select a time point only in the last seven days.
  • If you create an instance based on a time point, you need to pay for the created instance. For more information about how to bill an instance, see Billing items and pricing.
  • To create a Pay-As-You-Go instance, ensure that your account balance is sufficient.
