You can back up an ApsaraDB for MongoDB instance in either the automatic or manual mode, and restore it from backup files or to a point in time.
ApsaraDB for MongoDB stores its backup files in Object Storage Service (OSS) to reduce the storage space usage of its instances. You can perform an automatic or manual backup in the ApsaraDB for MongoDB console. For more information, see Configure automatic backup for an ApsaraDB for MongoDB instance or Manually back up an ApsaraDB for MongoDB instance.
|Standalone instances||Snapshot backup
Note The status of disk data at a specific point in time is retained.
|Snapshot backup affects the I/O performance of standalone instances.|
Note Physical data files of an instance are backed up.
|Physical backup runs on a hidden node, which does not affect the read/write performance of the primary and secondary nodes. Backing up a large volume of data may take a long time.|
Note mongodump is used to logically back up each database.
