--- title: Configuration --- ## Synchronous Replication By default, ParadeDB ships with asynchronuous replication, meaning transactions on the primary **do not** wait for confirmation from the standby instances before committing. **Quorum-based synchronous replication** ensures that a transaction is successfully written to standbys before it completes. Please consult the [CloudNativePG Replication documentation](https://cloudnative-pg.io/documentation/1.18/replication/#synchronous-replication) for details. ## Backup and Disaster Recovery ParadeDB supports backups to cloud object stores (e.g. S3, GCS, etc.) and point-in-time-recovery via [Barman](https://pgbarman.org/). To configure the frequency and location of backups, please consult the [CloudNativePG Backup documentation](https://cloudnative-pg.io/documentation/1.18/backup_recovery/).
