Remarks

For more information about reimaging a role instance, see Reimage Role Instance.

When the role instance is reimaged, the instance is taken offline and a fresh guest operating system image is applied. The role instance is then brought back online. Azure attempts to maintain data in any local storage resources when the role is reimaged; however, in case of a transient hardware failure, the local storage resource may be lost. If your application requires that this data be persisted, it is recommended that you write it to a durable data source, such as a Azure drive. Any data that is written to a local directory other than that defined by the local storage resource will be lost when the role is reimaged.
