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.

Transactionally consistent backup of partitioned storage

Methods, systems, and computer-readable media for single-tenant recovery with a multi-tenant archive are disclosed. A snapshot of a data store is stored at a first point in time. The data store comprises data elements provided by a plurality of clients. Incremental changes to the data store are stored after the first point in time. The incremental changes comprise changes to the data elements provided by the clients. A request is received to restore a particular subset of the data elements to a second point in time. The particular subset of the data elements are owned by a particular client. The particular subset of the data elements from the snapshot and a particular subset of the incremental changes are restored. The particular subset of the incremental changes comprise incremental changes to the particular subset of the data elements stored between the first and second points in time.
