Instead of a "recovery record", you will be much better served by using Parchive, specifically MultiPar to generate recovery files. Then, you can have more control over your recovery data, and it's much easier to use for large numbers of files in a complex directory tree. I use MultiPar myself in all of my long term data storage.
You can use MultiPar for basic verification of data integrity, which you will be doing much more frequently than actually repairing damaged data because data losses don't happen often if you have a good storage practices. However, I prefer Corz Checksum for mere verification because it's a lot faster, but it only does verification. I use both MultiPar and Corz Checksum - Corz Checksum for its speed in verification, and MultiPar for its data recovery abilities when an error is found.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Update on recovery records state: as a format specific feature they are supported for RAR and ARC archives. The suggestion of using an external, format-agnostic tool for error recovery is good, and I'll consider about it.
