Ok, so I have a tweet that's getting kind of popular on birbsite and I want to share the essence here too:
A guy tweeted that MySpace had lost all the music uploaded to it from 2003-2015. " An entire archive just... gone, forever."
So... this is your periodic reminder that uploading stuff to a website isn't an archive.
"As an artist that stores their art on twitter and a lot of art related sites. This troubles me deeply. Imagine if Twitter or even Youtube did this. Every video gone forever."
And just holy yikes, y'all. This gave me palpitations.
Please don't think of uploading/sharing stuff as "storing" it on any of these sites--twitter/tumblr/etc. There's no good retrieval process, you don't control compression, etc. It's nice to access stuff one's shared for resharing but not storage.
Do you have a contract to stop them from deleting that data? A retrieval mechanism to get you files at original quality? Some kind of data management or long-term plan?
It's not an archive, it's your content hitching a ride as long as it's useful for the site. As long as it's profitable. In whatever format it's profitable. Hence MySpace clearing server space.
If you DO have a Soundcloud, etc., consider checking out Preserve This Podcast http://preservethispodcast.org/ and learning more about what you might do to preserve your own files.
