As most of the organizations are moving towards cloud, they end-up in having some systems on-premises and some in cloud, and challenge is to have a unified solution for backup of data or applications.

Backup solutions are generally expensive affair not only from the perspective of solution license but also the cost of storage and retention.

There are few traditional backup solutions that provide solution for both cloud and on-premises as well but they treat the cloud as an endpoint, or static storage destination, similar to disks or tape. This approach looks simple but doesn’t take full advantage of an underlying cloud platform, and ultimately translates to an expensive, inefficient solution. For these third party solutions, administrative tasks require too much time.

Azure provides a solution for this problem with Azure Backup.

Azure Backup

it’s a service that can be used to backup and restore data in azure

This service can be used not only to backup Azure resources but also can be used for backup of on-premises resources. Following are few workloads or resources azure backup service can backup.

1. Azure VM
2. Folders
3. Files
4. Exchange
5. SharePoint
6. SQL Server
7. Physical Server or workstation
8. Hyper-V Virtual Machine
9. VMWare

The Azure Backup service has two types of vaults – the Backup vault and the Recovery Services vault. The Backup vault came first. Then the Recovery Services vault came along to support the expanded Resource Manager deployments.

There are many benefits of using Azure Backup service, following are few key benefits:

Automatic storage management
You don’t need to spend your time and energy to setup explicit storage, vault takes care of storage automatically. Also you just need to pay as you go for storage.

Unlimited scaling
As you are using Azure for storage, there is no such limit for storage and hence you can scale your configuration for virtually unlimited storage.

Multiple storage options
We always want to be double sure about backup, hence with respect to high-availability, Azure backup supports redundancy.

Locally redundant storage (LRS) replicates your data three times (it creates three copies of your data) in a paired datacenter in the same region.

Geo-redundant storage (GRS) replicates your data to a secondary region, hundreds of miles away from the primary location of the source data.

Unlimited data transfer
There is no limit for the amount of inbound or outbound data you transfer, also no charges for the data that is transferred.  (but there is certain condition for the cost, you can refer the same here)

Data encryption
Clients are always concerned about the security of data while storing it in cloud, however Azure backup encrypts data in transition and at rest.

Long term retention
Instead of switching backup copies from disk to tape and moving the tape to an off-site location, you can use Azure for short-term and long-term retention. Azure doesn’t limit the length of time data remains in a Backup or Recovery Services vault.
