Dropbox's major redundancy problem is it metadata being store in ONE site.
Data Lost when that ONE site goes down.
A Infinite Disk site is a computing location that has independent power, cooling, networking, security and ownership.
Infinite Disk uses "parity" instead of "copies" for data protection across SEVEN sites.
- Single Storage - SEVEN sites (3 parities - 75% redundant data)
Data Lost if FOUR sites gone
Infinite Disk needs less redundant data yet allows more sites to fail.
