Patent Title: Adaptive, time-based synchronization mechanism for an integrated posix file system

Abstract: Synchronization software in a computer operating system evaluates with respect to an exposure goal the ages of byte stream files queued for synchronization, and dynamically adjusts synchronization ("sync") capacity in response to the evaluation. The synchronization of byte stream files occurs at rates responsive to the sync capacity. Several parameters are used to adjust sync capacity: a lead time, the number of active sync tasks, and the priority of the sync tasks. These parameters are adjusted in a manner to impact system performance to the least extent possible.
