Abstract: Methods, systems, and computer-readable media for transactionally consistent backup of partitioned storage are disclosed. Backup operations are initiated for a first and second partition of one or more data stores. The position of a first marker is determined in a first log associated with the first partition. The first log indicates a sequence of changes for the first partition. The position of a second marker is determined in a second log associated with the second partition. The second log indicates a sequence of changes for the second partition. The first or second marker is determined to violate a transactional boundary across the first and second partitions. A position of at least one of the markers is modified such that the markers do not violate the transactional boundary.
