Shard MongoDB Cluster:
- 3-router
- 3-config
- 2-shard (3-replica's per shard)
We are trying to take incremental backup for every one hour. We gone through few google links, but no luck. As per our above setup, to achieve incremental backup we need to take mongodump with oplogs sperately from config, shard1 and shard2 secondary servers and we will store it in s3. But the problem is with restoration part. To restore, all those dump (config, shard1 and shard2) needs to be downloaded from s3 and restore it to its specific replicaset. which means config dump to config and shard dump to shard.
Is this the correct process or we have any other option to take incremental backup with single query?
Thanks
