Abstract
Technologies are described for implementing a system that schedules background workflows in a storage system. The background workflows may be automated maintenance tasks that require data movement, or any other tasks that would otherwise compete with normal input/output operations. Historical load statistics can be analyzed to estimate the preferred times in the future during which to schedule background workflows. After collecting data access statistics and usage patterns for several days or weeks, a number of averages can be calculated from the statistics at various natural periods of system utilization. For example, daily, weekly, or other periods. A weighted average can be established where weighting can place more emphasis on recent data. Such averages can serve as predictors of future loads having similar periodic relationships to the historical load data. Predicting future loads can improve the scheduling of background operations by avoiding conflicts with normal system operations.
