General-purpose storage v2 accounts have some of the same features as the v1 version, but they combine them with the tiering options of Blob storage accounts. In addition to that, v2 accounts also offer Geo Redundancy Storage for data stored in that account. V1 accounts only offer Read Access Geo Redundant Storage (RA-GRS).
Geo Redundancy Services enable customers to access and write data from different locations. Azure will take care of data and replication. So, there is no longer any need to replicate data or files through virtual machines or other external services.
