This topic describes how to restore data to the current ApsaraDB for MongoDB instance. This helps minimize the data loss caused by incorrect operations.
Prerequisite
The instance is a replica set instance with three nodes.
Background information
- The time required to restore data to your current instance varies depending on factors such as the data volume, task queue status, and network conditions. When the status of the instance changes to Running, the restoration is complete.
- If you restore data to your current instance, all existing data is overwritten and
cannot be restored.
Warning This operation is risky. We recommend that you restore data to a new ApsaraDB for MongoDB instance by point in time or backup set. Then, verify the data, and migrate the data back to the source instance by using Data Transmission Service (DTS). For more information, see Restore data to a new ApsaraDB for MongoDB instance by point in time or Create an instance from a backup.
