We backed up Spotify (metadata and music files). It’s distributed in bulk torrents (~300TB). It’s the world’s first “preservation archive” for music which is fully open (meaning it can easily be mirrored by anyone with enough disk space), with 86 million music files, representing around 99.6% of listens.
TBH I plan to migrate off Funkwhale to something more featureful and yea it was a bit of complex set up. Props to the devs tho, it’s open source, stable, and does what it says on the tin
