CockroachDB provides built-in high availability (HA) features and disaster recovery (DR) tooling to achieve operational resiliency in various deployment and use cases.
  • HA features ensure continuous access to data without interruption even in the presence of or disruptions to maximize uptime.
  • DR tools allow for recovery from major incidents to minimize downtime and data loss. Diagram showing how HA features and DR tools create a resilient CockroachDB deployment.
You can balance required SLAs and recovery objectives with the cost and management of each of these features to build a resilient deployment.
  • Recovery Point Objective (RPO): The maximum amount of data loss (measured by time) that an organization can tolerate.
  • Recovery Time Objective (RTO): The maximum length of time it should take to restore normal operations following an outage.
For a practical guide on how CockroachDB uses Raft to replicate, distribute, and rebalance data, refer to the .

High availability

  • : CockroachDB’s built-in stores data safely and consistently on multiple nodes to ensure no downtime even during a temporary node outage. allow you to configure the number and location of to suit a deployment.
    • For more detail on planning for single-region or multi-region recovery, refer to or .
  • : Capabilities built in to CockroachDB to perform routine maintenance operations with minimal impact to foreground performance. For example, , , and .
  • (Preview): A cross-cluster replication tool between active CockroachDB clusters, which supports a range of topologies. LDR provides eventually consistent, table-level replication between the clusters. Individually, each active cluster uses CockroachDB multi-active availability to achieve low, single-region write latency with transactionally consistent writes using Raft replication.

​
Disaster recovery

  • : Point-in-time backup and restore allows you to roll back to a specific point in time. Multiple supported providers means that you can store backups in your chosen provider. allow you to configure backup frequency for lower .
  • : A cross-cluster replication tool between an active primary CockroachDB cluster and a passive standby CockroachDB cluster. PCR provides transactionally consistent full-cluster replication.

​
Choose a DR strategy

CockroachDB is designed to recover automatically; however, building backups or PCR into your DR plan protects against unforeseen incidents.
