Abstract: Methods and systems for generating a cluster consistent backup of a distributed, master-less database cluster is provided. One method includes a first phase of a backup operation where a crash consistent backup of the various LUNs used by the cluster nodes is taken. The crash consistent backup is then transformed into a cluster consistent backup during a second phase of the backup operation.

Abstract: 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.
