SQL with Manoj

 
Backup to Azure was made available with SQL Server 2012 SP1 CU2. It provided significant cost savings versus on-premises costs of onsite/offsite storage, and device maintenance and better scalability than logical drives connected to Azure machines.

But backup to Azure was comparatively slow, and the maximum backup size was 1 TB, till SQL Server 2014.

 
Now with SQL Server 2016+ backup to block blobs offers more cost-effective storage, performance increases with backup striping and a faster restore process, support for larger backups, up to 12 TB, as well as granular access and a unified credential story.

Backup to block blobs also supports all of the existing backup and restore features, with the exception that appends are not supported.
