Abstract
Methods, systems and computer program products for high-availability computing. In a computing configuration comprising a primary node, a first backup node, and a second backup node, a particular data state is restored to the primary node from a backup snapshot at the second backup node. Firstly, a snapshot coverage gap is identified between a primary node snapshot at the primary node and the backup snapshot at the second backup node. Next, intervening snapshots at the first backup node that fills the snapshot coverage gap are identified and located. Having both the backup snapshot from the second backup node and the intervening snapshots from the first backup node, the particular data state at the primary node is restored by performing differencing operations between the primary node snapshot, the backup snapshot from the second backup node, and the intervening snapshots of the first backup node.
