Systems and methods for backup and restore of distributed master-slave database clusters

摘要

Methods and systems for a distributed database cluster are provided. One method for the distributed database cluster having a plurality of logical partitions, where each partition is used to store a plurality of replicas for a database, and each of the plurality of replicas are managed by one of a plurality of nodes includes preventing any topology change in the distributed database cluster; capturing a topology of the distributed database cluster prior to a first backup phase of a backup operation; generating a snapshot of all logical objects used by all active nodes to store the plurality of replicas of the database; initiating a second phase of the backup operation at a recovery node using the backup topology metadata after the first phase of the backup operation; and cloning snapshots of the logical objects from the first phase of the backup operation.
