Is there an open source archiver with integrated error correction code? (preferably windows 7, linux is ok, too)
presently the most stable procedure for me seems to be archiving with 7z and then creating recovery file sets using multipar (http://multipar.eu/).
So far I've seen, that rar-archives including a recovery record get unrecoverable if the change is in sensitive areas, even if only single bits are changed. Solution with additional par files is far more stable and at the same time notably smaller w.r.t. to archived data volume, alas it has several drawbacks:
- process requires an additional program
- process generates two additional files
I'd prefer the approach the rar authors have chosen (including recovery record in achive file), but it should be more resilient against damage
