US Patent 11188232 Enhanced storage compression based on activity level

Techniques for evaluating data sets for compression processing may include: receiving first information for a data set, the first information including I/O activity information for the data set, a service level objective for the data set, and a size of the data set; determining, in accordance with the first information, whether the data set meets criteria indicating a specified level of importance and a specified level of I/O activity; responsive to determining the data set meets the criteria, sending second information identifying one or more storage objects of the data set to a compression engine, wherein the one or more storage objects of the data set are identified as having the specified level of importance and at least the specified level of I/O activity; and performing processing, by the compression engine using the second information, to determine whether to compress first data stored in the data set.
