Patent ID: 8661067

Claim:
A method for optimizing data migration and recall in a computing storage environment, by a processor device, comprising: analyzing data stored in the computing storage environment over a predetermined period of time; identifying a usage pattern of a portion of the data during a time window within the predetermined period of time; calculating a median length of time the portion of the data is used during the time window; adding the median length of time to an additional time calculated from the median length of time to generate a predictive usage length; placing the portion of the data having the usage pattern on a preemptive recall list; preemptively recalling the portion of the data having the usage pattern from the preemptive recall list in advance of a usage time, the usage time predicted by the usage pattern for the portion of the data to be accessed; after preemptively recalling, determining whether the portion of the data has not been accessed during the time window within the predetermined period of time; and removing the portion of the data from the preemptive recall list, in determining the portion of the data was not accessed during the time window within the predetermined period of time.
