Does anyone use it for family photo backup for generation to pass on? I am struggling to come up with a good back up solution that last ages.
Buy a new hard drive every year, make it your primary drive. The previous one becomes your backup.
Or just keep it attached to your system, so spyware, adware, and the NSA will make free backups for you!
get some used LTO-5 / LTO-6 drive if you have some desktop/server to plug it in
Blu-ray drives are becoming increasingly rare sadly, so it's not great to hand over to others in the years ahead. An external hard disk drive kept safe and secure might be your only option. I had the same issue 6 years ago winding down my company and archiving data. Only sensible options were M-DISC and external hard disks.
