Abstract: Methods and systems for a distributed database cluster storing a plurality of replicas of a databases are provided. One method includes locating by a processor, a timestamp of a last stored record in a backup copy of the database from a plurality of logical partitions for a point in time restore operation; identifying by the processor, an operation log for each logical partition with the last stored record, the operation log providing transaction details associated with the database; splitting by the processor, the operation log for each logical partition by ignoring transactions that occurred prior to the timestamp of the last stored record; and using by the processor, the split operation log for restoring the database to the point in time.
