An alternative is including PAR2 files.

Understanding CD-R and CD-RW (2003) [pdf]
Not only that but if you budget for an expected error rate of let's say 10% you can use par2 to create additional files that add that redundancy to your archives.

Side-by-side: WinRAR, PeaZip, 7-Zip, WinZip
That's the same reason I do archive files. For parity I personally use (https://github.com/Parchive/par2cmdline) which does create extra files, so I can see how WinRAR would have something to add there.

FSArchiver – Filesystem Archiver for Linux
Here's the first example I could find.
https://pthree.org/2014/04/01/protect-against-bit-rot-with-p...
Basically, you take a normal TAR file and creates external parity files that can be used to recover data in the case of bitrot. Something like this would have been great to have on a few data files I had to retrieve from tape that ended up with a bit flip somewhere in the network > disk > tape > disk process.
However, it doesn't look like the program is maintained anymore...
