Add an option to add any tipe to redundancy to the archive like PAR2 or any other algorithm to be able to add a percentage of redundancy making the output file a bit resistant to disk sectors corruption it would be awesome and i woud use it a lot.

    Mi disk is slowly dying and a archive with important files got corrupted.

    I think this would be a great feature to bring to 7zip and is the sole reason I still use winrar in some cases for their recovery record. Yes you can create par2 backup files of a 7z archive but it would be nice to integrate that feature directly into 7zip as a flag that would include the recovery info in the archive.
