Is there some way to use CDs / DVDs / Blu-Rays as an incremental backup target? It'd be nice to take something like Restic, aim it at some hot backup HDD, then when enough deltas have been written to that volume have it burn a disk. It would be great if the entire experience is "if the drive is open, take the disk out, label it (according to some scheme), shelve it, and drop a new blank disk in".

- TacticalCoder 2y ago> When a 32Gb USB stick is $3, why are you thinking about a 1Gb CD? I've got data CDs from 1998 still reading fine. There are CDs and DVDs listed in TFA as having 50 to 100 years of longevity. How's that 32 GB stick going to do in 50 years if left untouched from now till then? I've never heard about USB sticks for long term archiving.
