We backed up Spotify (metadata and music files). It’s distributed in bulk torrents (~300TB), grouped by popularity.
This release includes the largest publicly available music metadata database with 256 million tracks and 186 million unique ISRCs.
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.
Step 1: Buy £6,000 worth of identical hard drives and a motherboard with 16 SATA ports. Or £12,000 worth and a RAID 1 server rig. Or £24,000 and RAID 6
6k for 10TB?
A Raspberry pi with a sata hat and 16TB hard disk could download and serve this for well under 500 quid.
An off the shelf 4 bay NAS with 4x 6TB drives in raid 5 would give you 15TB or so formatted capacity with redundancy. That would easily be under 2k… Jeez grab 2 and sync contents to a second location… even a third location… Still under 6k.
You can get PCI cards to add more sata ports, they don’t all need to be on the motherboard
