How is the secondary node selected during MongoDB backup operations?
The IntelliSnap full backups of MongoDB databases are taken on the secondary node. If there are multiple secondary nodes available, then the secondary node with the least priority is selected for backup. If all secondary nodes have the same priority, then the first node that appears in the list is selected for backup.
How do I create a new cluster from an existing backup?
To create a new cluster from an existing backup, perform the following steps:
-
Create a dummy MongoDB instance.
-
Perform a point-in-time browse by selecting the end time as the end time of the full backup that you want to restore.
-
Browse the replica set or sharded cluster backup and select out-of-place restore.
-
Select a dummy instance as the destination cluster.
-
For each shard or the replica set, select the client node, port, and dbPath on the destination client.
-
Complete the restore.
The new cluster is ready.
