如何提高 Azure 存储帐户的可用性？

Question

For Azure storage accounts the SLA for write requests is 99.9% regardless if I'm using LRS, ZRS, GRS or RA-GRS. Is there a way to increase the SLA for write requests on the storage account?

Eg is there a good way to fail over to another storage account in another region?

The accounts don't have to contain the same data. I just want to always be able to store the blobs.

Of course, Azure storage itself provides this feature, you can refer to the document Initiate a storage account failover .

Before you can perform an account failover on your storage account, make sure that your storage account is configured for geo-replication . Your storage account can use any of the following redundancy options:

1. Geo-redundant storage (GRS) or read-access geo-redundant storage (RA-GRS)
2. Geo-zone-redundant storage (GZRS) or read-access geo-zone-redundant storage (RA-GZRS)

You will see an interface like this:

My suggestion is to increase the number of retries for write requests, maybe the example here can help you, you can use BlobClientOptions .
