Databricks says Lakebase Postgres restores a 100 TB database in seconds using branch-based restores. The restore is a metadata operation that creates a branch at a point in time, referencing existing immutable history in decoupled storage without copying data or replaying WAL. Recovery time stays near-instant regardless of database size.
Restoring a 100 TB database with Lakebase Postgres takes seconds.
How?
A branch-based restore is a metadata operation. It creates a branch at a point in time, referencing immutable history that already lives in decoupled storage. No copying data, no replaying WAL. Recovery is near-instant regardless of database size, and simple enough for agents to use in branching and undo workflows.
