Abstract
Embodiments of the present invention provide systems and methods for adjusting synchronization rates of volumes. Volumes and their copies (i.e., mirrored volumes) provide physical or virtual storage on a data storage medium. Depending on the function (i.e., the purpose) of mirrored volumes, a certain synchronization rate is recommended. Embodiments of the present invention provide systems and methods for an automatic dynamic adjustment of individual synchronization rates by adapting to changes in system workloads in order to avoid degradation of user-driven input/output (IO) and to efficiently achieve nearly 100% synchronization for all mirrored volumes.
