description To generate a recovery time estimate in a transaction environment, a system includes a recovery manager, a recovery file containing recovery data, a store of historical restart data, and a recovery time estimation component. The recovery manager includes a component which is operable to measure the volume of active data on the recovery file, and to generate a recovery time estimate based on the measured volume and the historical restart data. This recovery time estimate can then be used as a characteristic of the system's keypointing policy to provide a more flexible and efficient keypointing procedure.
