Answer 2

Hi

Yes, highlighted option is enabled but still backup is getting failed.

I assume backup is getting failed due to having dynamic disk on virtual machines.
How can we take backup if VM disk is set as dynamic.

Answer 3

Is there any solution for this.

Answer 4

Hi,

Please also check the checkpoint settings of the VM, if you selected "Production checkpoints" before, please change to "standard checkpoints", check if it could work.
