Couchbase Disaster Recovery
Couchbase provides two complementary DR mechanisms:
| Mechanism | RTO | RPO | Use case |
|---|---|---|---|
| XDCR (active-passive) | Minutes | Near-zero (async) | Regional failover, geo-distribution |
| XDCR (active-active) | Seconds | Near-zero | Multi-region writes |
| Backup + restore | Hours | Hours (backup interval) | Data corruption, accidental deletion |
| Intra-cluster failover | Seconds | Zero (synchronous replicas) | Node failure within a cluster |
RTO / RPO Definitions
RTO (Recovery Time Objective): maximum acceptable downtime after a failure.
RPO (Recovery Point Objective): maximum acceptable data loss (measured in time).
