Disaster Recovery plan for Locally Redundant Storage Blobs

    Question

  • Hi,

    does anyone have plans to move storage in the event of a DC outage? we use LRS blob storage for files related to an app we run in Azure.  If the DC goes down for example and we have to move we can stand up another instance (Web + SQL) pretty quick somewhere else.  But the files are the issue.  Does anyone actually include a physical move of storage as part of a BC or DR plan?  Right now my DR plan covers the app, the SQL but the storage is a question mark.  Would using GRS blobs be the answer? 

    thanks,

  • Greetings,


    For Disaster Recovery, you could opt for either Geo-Redundant Storage or Read-access Geo-Redundant Storage replication for your storage account. If you choose Read-access geo-redundant storage (RA-GRS) (recommended) for your storage accounts, you will have read access to your data from the secondary region. You can use tools such as AzCopy, Azure PowerShell, and the Azure Data Movement library to copy data from the secondary region into another storage account in an unaffected region, and then point your applications to that storage account for both read and write availability.

    Hope this helps!

  • Greeting;

    as shihab said, for Storage you have the two options, Geo-Redundant Storage or Read-access Geo-Redundant Storage. This will insure that data on Storage account is replicated to other region.

    another point to consider, is Backing up your data through Azure and chose geo replication.
