You can refer to the remote backup configuration section:- [Set up and configure - Percona Backup for MongoDB](https://docs.percona.com/percona-backup-mongodb/install/initial-setup.html#configure-remote-backup-storage) for taking backups in S3 OR S3 compatible systems such as Google cloud storage (Bucket) etc.

For a complete setup guide of PBM in Mongo ReplicaSet/Shard environment you can refer to the below manual.

> **[Percona Backup for MongoDB - Set up and configure](https://docs.percona.com/percona-backup-mongodb/install/initial-setup.html)**

Let us know if you still having any further concerns!

You will need a dedicated pbm-agent for each mongod process running. You can clone the existing systemd service and change the configuration to deploy a 2nd service. Doc linked above should be helpful
