I know sdf had issues with media storage before, but that was late last year/early this one. There's noy been an update to lemmy in the week that you've joined.
Sort of. If you check the url of thumbnail images - they'll all be from your local instance.
Some images are also federated. Take this post, for example. The link is to lemmy.world, but the thumbnail and image itself are served by lemmy.cafe.
I've never really delved into what exactly decides whether to federate a particular bit of content or not, but there's definitely more than just text being stored.
Simple things. Lemmy, for instance, has grown to ~60GB since June las year. And that's just the db and federated media since I don't really havr any uploads. The big instancea are easily into the hundreds od gigs - I know lemmy.ca had over 300GB of media alone last autumn.
On a more consumer level - high quality 4k media eats up storage pretty fast. The phones taking pictures and video in higher and higher quality - space requirements will only ever go up.
Hey, I know your username! Familiar from the reports I'm getting 😁
On a more serious note - there's no such thing as unbiased. I'd like to believe I run my instance in a fair way, but I can't guarantee you'd like my definition of fair.
LibreOffice being FOSS probably means developers are mostly using it together with other FOSS. This brings some benefits, like a journaled filesystem, that sort of make the autosave useless. That recovery process that failed for you? It wouldn't have on something like btrfs or ext4 and, consequently, you wouldn't have been in a position where you're typing up this post.
Having said that, on bs OSes like windows autosave probably should be the default.
Well, you bastard. You're doing well!!!
