We are happy to announce Azure Backup
has increased the size of datasources that can be protected to 54400 GB from 1700 GB. For customers with large volume fileservers (greater than 2TB) that want to backup to Azure this updated feature will be very helpful. It will be applicable to all datasources and measured in the following ways:
Why 54400 GB?
||The amount of data being backed up from single volume of a machine. This is applicable for the volumes being protected on both server and client machines.
|Hyper-V virtual machine
||Sum of data of all the VHDs of the virtual machine being backed up
|Microsoft SQL Server database
||Size of single SQL database size being backed up
||Sum of the content and config databases within a SharePoint farm being backed up
||Sum of all Exchange databases in an Exchange server being backed up
||Each individual copy of BMR or system state of the machine being backed up
Azure Backup uses VHDX technology to backup these large datasources. The maximum size of the VHDX is 64 TB (65536 GB) and Azure Backup reserves some space for operational metadata. We will continue to optimize and increase the usable space but for this release we have pegged it to 54400 GB.
