How to apply the recommendation
- Click View in Portal to open the Azure Portal on the correct resource.
- Select Configuration in the menu.
- Select LRS in the Replication drop-down.
- Click Save in the top header.
You can set the replication setting for your storage accounts to GRS (Geo-redundant storage), RA-GRS (Read-access geo-redundant storage), or LRS (Locally-redundant storage).
GRS and RA-GRS will have your data replicated in another data center in case of a disaster in the primary data center.
GRS and RA-GRS slow down write operations to the storage because the data must be replicated to the secondary data center and this type of replication cannot be used as a safeguard against user or application errors.
LRS however, creates 3 copies of your data within different locations of a single data center. The only situation where your data can be lost permanently is if a disaster would affect the entire data center.
Switching your storage account setting to LRS will reduce your costs and speed up your write operation.
Note: GRS is the default option when creating a new storage account in Azure.
A storage account must not be empty and must be set to GRS or RA-GRS to be considered for this recommendation.
