Hello @金 泰弘 Apologies for the delayed response!

Is it possible to configure the above three cases on a single virtual machine and a management disk connected to the virtual machine?
Not all three cases can be achieved with a single VM. Because, By default, Backup takes full VSS backups. Meaning (Compute+Storage = VM+Disks), you cannot backup only VM or only disks. Reference doc - https://learn.microsoft.com/en-us/azure/backup/backup-azure-vms-introduction#backup-process

However, you can leverage different restore functionalities offered by Azure VM backup. See the doc link - https://learn.microsoft.com/en-us/azure/backup/about-azure-vm-restore#restore-scenarios

Also, how many hours would it take to backup and restore the virtual machine and the management disk connected to the virtual machine with the following specifications?
Depends on the network bandwidth, amount of data transfer etc. However, it takes less than 24hrs for restore.

Hope this helps. Feel free to ping with questions for further assistance.
