If they’re considering optical media, typical BD-R, while viable, may not be be the best choice. BD-R M-Discs would probably be a better choice for backups. Especially if they’re planning on needing access to the data over a period of decades, which would be potentially useful for familiy photos/videos and critical documents.
They are more expensive, as is the drive needed for them, but not by enough to be out of reach or even unreasonable given the additional durability of the discs.
used to go once a month or so, but then covid lockdowns happened and the barber I liked actually complied with the regulations (which is a good thing), which made it more inconvenient than I though it was worth to get a haircut. At first I figured I’d go back once things started returning to normal, but then that took a while and I never did. So, I haven’t gotten an actual haircut in almost six years.
I did start getting the ends cleaned up every six months or so about a year ago though.
