i can't even remember the last time i saw an optical disc. it must be several years.
They're a very common form of personal backup. A few discs and an USB writer and you get a very long lasting medium for passwords, personal files, family photos etc.
Can also archive multimedia of course, the smallest discs are 25 GB and can pack a few films, a season of a series, or a lot of music.
i guess, but they're not great for backup. Eps. R/RW optical media doesn't last that long (5-10 years) and is easily damaged. You'd be better off with tape for long-term storage. or an M-Disk or some similar magnetic backup solution.
I beg to differ. I've been backing things up to optical for 25 years now with minimal issues. CDs could be easily scratched but it hasn't been the case for DVD and BR.
M-DISK uses in-organic substances that make the discs mostly immune to exposure but it's a more recent invention. Proper storage and handling still goes a long way towards protecting discs even if they're not in-organic.
