These functions do not affect the VM lease on its disk(s), do not require VM shutdown, and do not interfere with VM operation.

The functions Get-AzureRMUnmanagedDiskSnapshot, New-AzureRMUnmanagedDiskSnapshot, and Remove-AzureRMUnmanagedDiskSnapshot have been added to the AZSBTools module to simplify management of unmanaged disk snapshots via PowerShell.

Convert managed to unmanaged disk (separate post on that).Manage disk snapshots list, create, delete (the subject of this post).Determine the amount of used disk space (separate post on that).Well, using my own advise I find it hard to use unmanaged disks via PowerShell to perform routine Azure infrastructure management tasks such as: Given that used space is often as little as 1% of the allocated space, I highly recommend against using managed disks at this time () In short, managed disks come at the cost of paying for allocated space not used space. This is because we’re billed only for the 10 GB used space not the 1023 GB allocated space, whether the VM is up and running or powered off and deallocated. In comparison, the same 1 TB unmanaged disk using the same 500 IOPS with 10 GB of used space costs $0.45/month (10 GB * $0.045 per GB). We still pay the $41/month for this 1 TB disk including the 990 GB unused space. If we use 10 GB of this disk we pay $41/month even if we power off and deallocate the VM. Consider Standard LRS USEast region pricing for example. This is a pretty nice feature but it comes at a steep price. Managed Disks handle the storage account creation/management to avoid hitting the 20k IOPS standard storage account limit for example (no more than 40 standard disks in the same Storage Account 500 IOPS each). Although the same snapshot capabilities are available for unmanaged disks, there are no PS cmdlets to provide similar functionality for unmanaged disk snapshots. The AzureRM.Compute PowerShell module (v 5.9.1 as of ) provides the Get-AzureRmSnapshot, New-AzureRmSnapshot, and Remove-AzureRmSnapshot cmdlets to handle disk snapshots of managed disks. 3 new functions have been added to the AZSBTools PowerShell module to view, add, and delete snapshots of unmanaged Azure disks
