What Types of Data Could I still be using for CD-R’s and DVD-R’s in 2021?

702 mb and 4.3 gb is entirely too small for any kind of long term archival projects of magnitude also Laser disks (at least in my experience) are not built to last.

Disks that I’ve burned in the 90’s and early 2000’s have been peeling and are now completely unusable.

So what kinds of data will fit in the limited size restriction while not being important enough to store for more than 4-5 years at a time?

  1. Slightly unrelated, I’m sad LightScribe isn’t a thing anymore

  2. Use DVD-R’s for OS Install Discs, or copies of movie DVD’s with all languages and Special Features.

  3. Boot disks. Most thumb drives don’t have write protect anymore so don’t make secure boot media. Sharing pictures, videos, etc. You can burn a disk, give it away, and not worry about needing a thumb drive to be returned. Permanent data. Things you don’t want alterable, burn it and it will never change.

  4. Probably documents, books, code, other text heavy stuff. As a third or fourth backup, not as the primary medium.

    Or alternatively, you can fit a Full HD movie or a 4K tv episode easily in a DVD as long as you use modern codecs and copy the files to your PC before watching.

    Or if you just have extra discs around you want to find use for, consider burning your PS1 or PS2 games to them. Good to have multiple backups if your originals fail.

  5. If you have the physical storage to store the increase of discs, you can store anything. The technique I use is to create a multi volume archive. Three tools here are 7zip, tar, datapacker or marginally, rar. This allows you to split the source data across multiple discs. But won’t protect it against media failure. And if you use 7z, rar, or other archivers you run the risk of loosing everything if one disc fails. So to reduce the impact of this I perform the next steps.

    When creating the archives, I specify that the volumes don’t go above 80% of the destination media. I then use PAR2 to create recovery files make sure these files also don’t go above 80% of the destination media. You can set the redundancy to suit how important the data is for you. Any surviving recovery files along with any surviving media should allow you to salvage up to the limit of the redundancy specified earlier. While PAR2 will recreate any missing data and salvage files, there’s a hidden single point of failure that we can mitigate against. Once on the disc, it is possible that the area of the disc where the file-system stores it’s metadata gets corrupted thus losing the entire disc. This where the final step comes in, and the reason why you’ve not been using the full capacity of the disc.

    Turn the data and recovery files into ISOs for burning. Then feed those ISO files into DVDisaster. This tool has the ability to populate the spare space on the disc not occupied by the filesystem to create error correction data in a similar way to PAR2. The main difference is DVDisaster works to protect data *and* filesystem data. But, is tied to the individual discs that make up the archive. PAR2 is not, it protects across media. So you have two independent layers of protection that should protect you in most eventualities.

    All tools I have specified are either open source or can be processed by open source tools. This is important as we don’t want to lose access to our data due to not having the tools run out of support in the future.
