I don't trust cloud storage. But let's face it, the term "cloud" is
marketing-speak for "the internet but more expensive", so it's
probably more accurate to say that I don't trust online storage.

I always make local backups of anything I store online, to include
content hosted on the web or gopher. You just never know when a
service you rely on might go offline or become inaccessible.
Self-hosting is preferable, but online services can be convenient if
you're careful, and I'm aware that not everyone has the technical
know-how to self-host. So they are here to stay.

As an example, my RPG blog has been hosted at wordpress.com
since 2013. Wordpress, while considered a heavyweight blogging
platform, does make it easy to export or import your data, and their
XML export files are widely supported by other blogging platforms
and conversion utilities. I don't self-host wordpress because it
requires constant maintenance, so it's been easier to let wordpress
worry about that. It has worked well for over a decade for my
purposes.

Still, I think if I had to start over with a blog like that, I'd
just opt for self-hosted, static HTML or gopher. It's far easier to
backup and restore a static site, and is more secure than a dynamic
one.
