Concurrent checkpointing for fast recovery in object-based systems

Traditional checkpoint and recovery are based upon two basic assumptions. The first is the need to halt the computation in progress to save the state of the computation, i.e., take the checkpoint. The second assumption is that the entire state needs to be saved. These assumptions introduce fixed overhead into the system to take the checkpoint and consume space for variables whose state need not be saved. This research investigates a means of breaking these assumptions by developing an architecture that is capable of transparently saving the state of the executing process and of saving only that information required for recovery should an error occur. It also investigates a method of intermediate level recovery, i.e., recovery at levels above a single instruction and lower than that of checkpointing.
