Question

You manage a general-purpose v2 storage account currently configured with geo-redundant storage (GRS). The compliance team now requires that the data be protected against a datacenter failure within a single region while keeping the account in the same region, and they want zone-redundant storage (ZRS). You attempt to change the redundancy setting directly in the Azure portal but ZRS is not offered as an option. What must you do to achieve ZRS redundancy?

Accepted Answer

First change the account to locally redundant storage (LRS), then convert LRS to ZRS.

Answer

Change the account to read-access geo-zone-redundant storage (RA-GZRS) instead, which is the only zone-based option available from GRS.

Answer

Enable the geo-redundancy failover feature, which automatically re-provisions the account as ZRS.

Answer

Upgrade the account to a premium block blob account, which converts redundancy to ZRS automatically.
