This has been on my mind a lot as well, archiving my things online. I've been exploring my options, which is how I've found my way to dreamwidth. I'm tired of scares of other sites I rely on sinking and would rather invest in myself. I'm currently attempting to build a website- and you make me consider making a zip file as well.

You can't guarantee the service of any website you choose to host your stuff, so i guess we must keep making a mess and take up space wherever we go- be "fiendishly resilient" as you put!
