EDB Donates Klio Backup Tool to CloudNativePG, Previews Enterprise Postgres Add-Ons for Kubernetes

SALT LAKE CITY -- EnterpriseDB (EDB) announced at KubeCon + CloudNativeCon North America 2026 that it has donated Klio, a backup and recovery tool for Postgres on Kubernetes, to the CloudNativePG (CNPG) community, and is previewing two enterprise offerings built on the operator. The news follows CNCF’s acceptance of CNPG as an Incubating project on Nov. 10 and comes less than a week after EDB completed its acquisition of Altinity, creator of the Altinity Kubernetes Operator for ClickHouse software.

Klio Targets Near-Zero Data Loss

According to EDB, CNPG’s built-in backup options archive the Postgres write-ahead log (WAL) only as completed segments, so an outage can cost up to five minutes of lost transactions. Klio instead streams WAL continuously and keeps a local copy next to the cluster, so restores run at disk speed rather than pulling a full copy from remote storage. It encrypts data in transit and at rest with rotatable, customer-controlled keys, supports local volumes, S3-compatible storage or both, and lets a single Klio server protect many clusters while showing the health of each backup in one place.

Enterprise Previews Without an Operator Swap

EDB is previewing an EDB distribution of Klio with certified images, enterprise support and long-term-support releases, along with a new EDB Postgres AI Plugin for CloudNativePG that adds enterprise features such as transparent data encryption to open source CNPG without replacing the operator. Both are planned for general availability by the end of 2026, and community images remain free.

“By continuing to invest and give back across the open source communities behind Postgres, ClickHouse software, and the cloud-native ecosystem, we give enterprises the foundation to build that future at scale, on infrastructure they own and control,” said Max Romanenko, CTO of EDB.

Postgres and ClickHouse Under One Control Plane

With Altinity now part of EDB, the company is positioning both operators as a single multi-model data layer, EDB Postgres AI, running natively on Kubernetes. EDB said the shared declarative operator pattern allows teams to run transactional Postgres and ClickHouse analytics fed by change data capture under one operating model, and it plans to introduce integrated enterprise ClickHouse capabilities in the fourth quarter of 2026.
