Question about PBM Agent Deployment for 3-Node MongoDB Replica Set

1

Hi all,

I have set up a MongoDB cluster with 3 nodes, configured as a single replica set (1 replica set, 3 nodes: 1 primary and 2 secondaries). I am planning to use Percona Backup for MongoDB (PBM) for backup management. Using 3 EC2 Instances.

My question is:
Do I need to set up and run the PBM agent on all three nodes of the replica set, or is it sufficient to run the PBM agent only on the primary node?

If anyone can clarify the best practice here, I would appreciate it!

Thanks in advance.

Hi, you need to run PBM agent on all mongod nodes except arbiters (in case you have any). More info here: Initial setup - Percona Backup for MongoDB
