Abstract
A technique for storing data selectively tags write requests received by a data storage system based on whether each write request is directed to a file having a file type on an exclusion list, thereby producing a set of tagged write requests directed to a file type on the exclusion list and a set of untagged write requests directed to a file type not on the exclusion list. The method further includes persistently storing tagged data specified by the set of tagged write requests without first compressing the tagged data, and persistently storing untagged data specified by the set of untagged write requests after compressing the untagged data.
