Azure Storage (Blob)

Implementation guidance Internet connection to Azure (Azure Backup or Azure Blob storage) via the Azure Backup Server or 3rd party solutions (such as Commvault Simpana or Veeam Cloud Connect) hosted on premises.

Examples of business applications running on a virtualized or physical machine on premises.

Disk used by your virtual or physical machine.

Azure Backup Server orchestrates the replication of machines and manages the configuration of the failback procedures.

Azure Backup extends tried-and-trusted tools on-premises with rich and powerful tools in the cloud. It delivers protection for customers’ data no matter where it resides: in the enterprise data center, in remote and branch offices, or in the public cloud; while being sensitive to the unique requirements these scenarios pose. 

Virtual machine hosted on premises or on Azure that’s running an application such as SQL or SharePoint.

Blob storage stores the backup data and application on Azure.

Veeam Cloud Connect hosted on premises running on a virtual machine / physical machine. 

Cool tier on Azure Blob storage. Use cool tier for data that is less frequently accessed.

Hot tier on Azure Blob storage. Use hot tier for data that is frequently accessed.

Files and folders hold programs and files used by your virtual or physical machines.

Azure storage: industry leadingLocally Redundant Storage (LRS)

Zone Redundant Storage (ZRS)

Geographically Redundant Storage (GRS)

Read-Access Geographically Redundant Storage (RA-GRS)

How it worksMakes multiple synchronous copies of your data with a single datacenter

Stores three copies of data across multiple datacenters within or across regions. For block blobs only.

Same as LRS plus a multiple asynchronous copies to a second datacenter hundreds of miles away

Same as GRS, plus read access to the secondary access

Total copies 3 3 6 6

Why use itFor economical local storage or data governance compliance

An economical, higher durability option for block blob storage

For protection against a major datacenter outage or disaster

Provides read access to data during an outage, for maximum data availability and durability

Availability SLA 99.9% read/write 99.9% read/write 99.9% read/write 99.9% write 99.99% read
