Abstract:
Accurate recovery of a primary server at a recovery server is accomplished with reduced network overhead by maintaining at the recovery server checkpoints taken over time of the primary server and an intention log of logical transactions pending and complete by the primary server. The recovery server is brought to the operational state of the primary server as of failure at the primary server by recovering the most recent checkpoint and then executing the transactions indicated by the intention log as received but not complete as of the time that the checkpoint was taken.
