Supported MongoDB deployments¶

Percona Backup for MongoDB works with sharded clusters and replica sets. It doesn’t work on standalone MongoDB instances. This is because Percona Backup for MongoDB requires oplog to guarantee backup consistency. Oplog is available on nodes with replication enabled.

For testing purposes, you can deploy Percona Backup for MongoDB on a single-node replica set. To convert a standalone server into a replica set, specify the replication.replSetName option in the configuration file and then initiate the replica set.

Version added: 2.1.0

Physical restores are available for deployments with arbiter nodes. However, since these nodes don’t have the pbm-agent installed, you must manually stop them before the restore.
