There is, I think, a linux shareware version of rar, which I tried years
ago and found lacking a lot. Maybe they have improved, dunno. Also, the
first version of the algorithm was some kind of opensource, but I haven't
seen a linux version of that (and it couldn't compete with any of the
current compressors, any way).
The wikipedia says (under "Archiver features"):
Variable amounts of redundancy (recovery record) can be added to an
archive, making it more resistant to corruption. Even if parts of an
archive are damaged, it is possible to fully recover the stored data if
a large enough recovery record exists.
It is, of course, interesting, that a compression algorithm handles
internally things like volume spanning and redundancy.

Yes, there is a current shareware linux version here:

Just tried, and with the v3.60 SHAREWARE i can create archives with
Recovery Records, and even add them to an existing archive.... I'm not
sure what are the limitations, if any...
