Thisoption is chosen to protect against a region failure while also offering protection within a single data center for each region. Effectively, you get six copies of data (three in each region). Data is copied asynchronously across regions but synchronously within the data center. The following screenshot illustrates replication for GRS:

Now that you understand what GRS storage replication is, we will explore GZRS replication.

GZRS

This option is chosen toprotect against a region failure while also offering HA and protection within each region. Effectively, you get six copies of data (three in the primary region distributed across AZs, and three distributed within a data center in the secondary region). Data is copied asynchronously across regions but synchronously within the region and data center. The following screenshot illustrates replication for GZRS/ RA-GZRS:

Now that you understand what GZRS storage replication is, we can conclude this section on storage redundancy types. In the next section, we provide additional reading material to learn more about storage.

Top Tip

The archive tier of storage does not support ZRS, GZRS, and RA-GZRS redundancy options.

Further reading

That brings this section to an end. In this section, we have learned what storage accounts are, why they are necessary, and how they work.

Creating and configuring storage accounts

Now that we understand more about storage accounts and what to be aware of, we are going to create a storage account in Azure. A storage account needs to be in place before you can upload any data or files to Azure.
