You can protect applications that run in the Microsoft Azure infrastructure with managed disks using cloud native snapshots.
When you install the Commvault software, the installation creates a default array named Azure-Default-MSI.
Snapshots that are created by the Microsoft Azure snapshot engine are associated with the Azure-Default-MSI array.
The array uses REST APIs to perform snap operations on the Azure managed disks. When there are multiple disks, the array consolidates all the mount and unmount operations to these disks into one single REST API request, thus reducing the time taken to mount and unmount the disks.
By default, the snapshot engine leverages Microsoft's incremental snapshot type for the managed disks. Incremental snapshots are a cost-effective point-in-time backup of the managed disks, which store only the delta data from the last snapshot. If the incremental snapshot fails for any reason, the snapshot engine creates a regular full snapshot automatically. Microsoft's incremental snapshot solution has the following advantages:
-
Cost-effective solution to create snapshots that include only the differences from the previous snapshot.
-
Data aging and restore operations are the same as that for Commvault regular snapshots.
For more information on the restrictions and prerequisites for incremental snapshots, see Microsoft article Create an incremental snapshot for managed disks.
Key Features
You can use NVMe disks as the source on the Linux platform to run the IntelliSnap backups. To do this, you must install nvme-cli package on your source VM.
