   Hello and thank you for your attention. Here are the answers.
   > (1) should vm be resumed after deletion ?
   
   The VM gets resumed right after the snapshot deletion procedure: https://github.com/apache/cloudstack/blob/1bef11a9e56c664afb8e74254973cdfcb1350b1f/plugins/hypervisors/kvm/src/com/cloud/hypervisor/kvm/storage/KVMStorageProcessor.java#L1007-L1015
   
   > (2) should vm be paused when backup a snapshot ?
   
   The VM is being paused when the snapshot is being created, but then it resumes its work, so the snapshot is being copied to the secondary storage, some time passes and then the snapshot is being deleted from the image file without suspension of the VM, which could be quite a risky maneuver.
