backup for your backups

I don't take backup seriously. Most poeople don't either.

I'm starting to worry about it though.

PAR is a file format and system for using Reed-Solomon type error correcting codes to backup your backups. Even if some of your data burned onto a CD goes bad you can use the PAR file to fix it.
