Before we go deeper into the storage redundancy space it'd be helpful to better understand the building blocks of Azure global infrastructure as well as a few terms commonly used in high availability and disaster recovery in general.
With these in mind let's take a closer look at what Azure storage redundancy options have to offer.
Locally redundant storage (LRS)
Zone-redundant storage (ZRS)
Geo-redundant storage (GRS)
Geo-zone-redundant storage (GZRS)
Be aware of potential data loss! Always check LastSyncTime before executing the failover.
Hope this helps you get a good grasp of durability and availability options for your storage needs! For more details please refer to our documentation:
