Zone-redundant storage (ZRS) copies your data synchronously across three Azure availability zones in the primary region.LRS is the least expensive replication option, but isn't recommended for applications requiring high availability or durability.

Locally redundant storage (LRS) copies your data synchronously three times within a single physical location in the primary region.Azure Files offers two options for how your data is replicated in the primary region: Redundancy in the primary regionĭata in an Azure storage account is always replicated three times in the primary region. You might want to isolate file shares in separate storage accounts if they have different redundancy requirements. Therefore, all file shares deployed in the same storage account have the same redundancy setting. When you create a storage account, you choose a redundancy setting for the storage account that's shared for all storage services exposed by that account. For more information about storage accounts, see Storage account overview. The storage account represents a shared pool of storage that can be used to deploy file shares. Whether your data is replicated to a second region that's geographically distant to the primary region, to protect against regional disasters (geo-redundancy).Īzure file shares are managed through a common Azure resource called a storage account.How your data is replicated in the primary region.The factors that help determine which redundancy option you should choose include: When deciding which redundancy option is best for your scenario, consider the tradeoffs between lower costs and higher availability. Redundancy ensures that your storage account meets its availability and durability targets even in the face of failures. Azure Files always stores multiple copies of your data so that it's protected from planned and unplanned events, including transient hardware failures, network or power outages, and natural disasters.
