 Managed disks have two redundancy models, locally redundant storage (LRS) disks, and zone-redundant storage (ZRS) disks. The following diagram depicts how data is replicated with either model.

 LRS disks provide at least 99.999999999% (11 9's) of durability over a given year and ZRS disks provide at least 99.9999999999% (12 9's) of durability over a given year. This architecture helps Azure consistently deliver enterprise-grade durability for infrastructure as a service (IaaS) disks, with an industry-leading zero percent [annualized failure rate](https://en.wikipedia.org/wiki/Annualized_failure_rate).
