"Back in the old days" geezers like me would download anything we liked and keep "backup" copies because we knew we were one HDD crash/tableflip away from that data being gone forever.
Over the past 15(?) or so years, I've noticed more of an attitude of, "I don't care, if I lose it, it'll always be on the Internet and I can re-download it." Since YouTube and other video services have started taking content down, and the Internet Archive is on the ropes, younger folks are starting to learn that the Internet isn't forever.
Stupid things you said on social media as a teen, maybe. But a lot of media out there isn't.
My attitude never changed on this, which is why I RAID-6 and LTO-6 all of the data I feel is critical, and why Tiggi.es is in a replica cluster, copied to a RAID-6 volume daily, and backed up to LTO-6 every 3 days.
I'm paranoid about data loss and data availability in ways that many who haven't spent the better part of their career working in storage/Internet aren't. Data loss is almost inevitable. Almost. But data that isn't under your control can vanish without notice.
