Currently, the three specifications of the DDS support recovery from backup data. You can recover backup data according to business needs.
Instance Type
| Recovery Type | Application Scenario |
Stand-alone Version (Single-Node) | Recovering to this instance by backup point | Recovering to other stand-alone (single-node) instances by backup point |
Recovering the existing stand-alone version (single-node) backup data to this instance | Recovering the existing stand-alone version (single-node) backup data to other stand-alone version (single-node) instances or replica set instances | |
Replica Set | Recovering to this instance by backup point | Recovering the existing replica set backup data to this instance |
Recovering to this instance by point-in-time | Recovering the existing replica set backup data to this instance at a specified point-in-time | |
Recovering to new instance by backup point | Recovering the existing replica set backup data to new instance | |
Recovering to new instance by point-in-time | Recovering the existing replica set backup data to new instance at a specified point-in-time | |
Recovering to other replica set instances by backup point | Recovering the existing replica set backup data to other stand-alone version instances or replica set instances | |
Recovering to other replica set instances by point-in-time | Recovering the existing replica set backup data to other stand-alone version instances or replica set instances at a specified point-in-time | |
Cluster Version | Recovering to this instance by backup point | Recovering the existing cluster version backup data to this instance |
Recovering to this instance by point-in-time | Recovering the existing cluster version backup data to this instance at a specified point-in-time | |
Recovering to new instance by backup point | Recovering the existing cluster version backup data to new instance | |
Recovering to new instance by point-in-time | Recovering the existing cluster version backup data to new instance at a specified point-in-time | |
Recovering to other cluster version instances by backup point
| Recovering the existing cluster version backup data to other cluster version instances with the same number of shards | |
Recovering to other cluster version instances by point-in-time | Recovering the existing cluster version backup data to other cluster version instances with the same number of shards at a specified point-in-time |
