Abstract:
Systems, methods, and computer readable media for lazy compression of data incoming to a data storage entity are disclosed. According to one aspect, a method for lazy compression of data incoming to a data storage entity includes defining at least a portion of the data storage area within the data storage entity as a compressed logical unit for storing at least some data in compressed form; receiving a command to write data to the compressed logical unit, and, in response to receiving the command to write data to the compressed logical unit, writing the data in uncompressed form; and monitoring for a trigger condition, wherein, upon detection of a trigger condition, at least a portion of the uncompressed data within the compressed logical unit is compressed.
