      Description

      After parity files are archived into a parity HAR, a change in the source file does not cause the HAR to be recreated. Instead, individual parity files are created for the modified files but the HAR is not touched. This causes increased disk usage for parity data.

      The parity HAR could be recreated if a certain percentage of files in the HAR are determined to be outdated.
