Terraform State File in storage account

We have Terraform state file stored in the Azure Storage Account. In case storage account went down we will be screwed. What is the best way to store the file? where?

Solution

  • AFAIK, there are two methods to store a terraform state file i.e. Locally in your machine or in a Storage account in azure .

    In case storage account went down we will be screwed. What is the best way to store the file? where?

    As confirmed , You are using Standard_LRS which is not preferred as per the Microsoft Document if you are looking for high availability.

    Locally redundant storage (LRS) copies your data synchronously three times within a single physical location in the primary region. LRS is the least expensive replication option, but is not recommended for applications requiring high availability or durability.

    So, as a solution you can change the storage account type as per your requirement to Standard_GRS or Standard_ZRS so that your data is present in two locations i.e. replicated.
