Machine backup policy
Machine backup policy provides a backup functionality to the workload.
For more information on the machine backup functionality, refer to https://www.acronis.com/en-us/support/documentation/CyberProtectionService/index.html#32952
The following example can be used when creating a protection plan with this protection policy:
