This is nifty! I used par2 when I was shooting video and archiving to optical media; I'd include the parity files on the media, and also keep copies elsewhere.

This is nifty! I used par2 when I was shooting video and archiving to optical media; I'd include the parity files on the media, and also keep copies elsewhere. I think the parity files would be able to pull in data even from corrupt, re-ripped iso files if the media started failing.
- dehrmann 6y agoOptical media already use similar error correction, but the redundancy level isn't configurable, and it's stored physically close to the data, so it's somewhat less effective than what you're doing. That said, having recently looked at some 20-year-old discs, professionally pressed discs held up well, and bargain basement CD-Rs had a lot of physical failures, even when stored indoors in a dark case. So par2 is good, but make sure you're getting high-quality media, too. Maybe M-Discs?
- bartvk 6y agoI still use it for our family photos (150 gigs). The par2 files cost about 5% additional storage, which I don't mind. My backups are online, on external SSDs and harddrives. I've had unexplainable corrupted photos before and I wish to take no chances.
