Hard to really judge without knowing how much excess storage they started the year with.
- londons_explore 10y agoSome large organisations store as many as 15 copies of each bit of user data... When you have a database which keeps redundant master slave replicas and mutation logs, a backup system which keeps many previous backups on-site and offshore on tapes, a storage system that has many RAID mirrors per host, a distributed filesystem which stores replicated chunks of data across an entire datacenter to handle host failure, and you keep copies of the entire lot in multiple datacenters for accessibility during planned downtime and natural disasters.
