No, it's not ideal. Way too many files makes your backup directory cluttered. I really dislike PAR for generating external checksums...at least 2 for each file. I wish sb. integrated ECC into DAR...
Actually I'm going to ask the author of FreeArc to integrate DAR features into his archiver, it would be the best option. But not yet, he has many more important things to do first.

I doubt nobody did it. Because it's simple and useful. Just nobody publishes simple administrative scripts.
