Whenever using Veeam Backup for Azure, there are two recommended options for creating multiple copies of the backup data. First is a backup copy job from an external repository. The second option is to rely on the native storage redundancy provided by Azure, such as geo-redundant storage (GRS) or read-access geo-redundant storage (RA-GRS). The purpose of this article is to explore this second option by leveraging RA-GRS for achieving backup redundancy across two Azure regions.
As a quick reminder, with RA-GRS and GRS, the data is stored in two separate locations, with one being the primary location and the other being a secondary location. The secondary location is located in a different geographic region than the primary location, ensuring that data is safe even in the event of a regional outage or natural disaster.
For more detail on the different types of Azure storage check out my previous writeup here.
For the purpose of testing, A RA-GRS storage account was provisioned in Australia East from which Azure automatically configured the secondary region to Australia Southeast. This paired secondary region is determined based on the primary region and can’t be changed. Access to the storage account is via public endpoints.Continue reading
