No target.
I will keep this open as long as it's possible. It's up to others to start as many Lemmy instances as possible, and the Lemmy devs to create a better join-lemmy with a rotating 'recommended server' preferring smaller instances.
But that's difficult. Because you also don't want 1000 users to land on someone's Raspberry Pi instance without backup which they can just stop if they get bored of it. Same issue goes for Mastodon as well... but that's being worked on.
I created mastodon.world just because it sounded cool and it was available.
The first banner I used for that was a 'Hello World' image so yes that was referring to scripting.
Later I registered some more .world domains like Lemmy.world (and calckey.world and some more yet to be launched)
Rsync works fine for most data. (I use borgbackup)
For any database data, create a dump using pg_dump or mysqldump or whatever. Then backup the dump and all other volumes but exclude the db volume.
Yes.
