Azure Backup

 Traditional backup solutions have evolved to treat the cloud as an endpoint or static storage destination, similar to disks or tape. While this approach is simple, it is limited and does not take full advantage of an underlying cloud platform, which translates to an expensive, inefficient solution.

other solutions are expensive because you end up paying for the wrong type of storage or storage that you dont need.  Other solutions are often inefficient because they dont offer you the type or amount of storage you need or administrative tasks require too much time. In contrast, Azure Backup delivers these key benefits:

Multiple storage options:

An aspect of high-availability is storage replication.

Azure Backup offer two types of replications:

1. LRS : All copies of data exist within the same region 

2. GRS: GRS replicates your data to a secondary region which is Azure paired regions.

Long-term retention:

you can use recovery services vaults for short-term and long-term data retention. Azure does not limit the length of time data can remain in  a Recovery Services vault. You can keep data in a vault for as long as you like. Azure Backup has a limit of 9999 recovery points per protected instance. See the backup and retention section in this article for an explanation of how this limit may impact your backup needs.
