In this situation if the restore operation fails then the software will rollback using to the snapshot created in the first step. And only after all these steps are performed the target VM is started.After data is recovered software disconnects virtual disks from the Virtual Appliance and sends command to remove the technical snapshot created in the first step.If Acronis Windows Agent is used or the Hot-Add functionality is not available, recovery is performed via network directly to the target VM. After the snapshot is created Acronis software mounts virtual disks to the Virtual Appliance and recovers data to the existing disks.This technical snapshot is required to be able to rollback in case the recovery operation fails. When the recovery operation is started Acronis software powers off and creates a quiescied snapshot of the target VM using VMware API.In case original VM exists, the software uses the following algorithm: When recovery is performed to the original location, Acronis Backup for VMware (Acronis vmProtect) tries to locate the source VM using its InstanceUUID and if the VM is missed then the new VM will be created. There are two ways for recovering virtual machines: to the original VM and to a new one. The recovery operation can be performed either to the virtual machine (original or a new one) or using the File Recovery feature to restore only files and folders from a virtual machine backup. The technology of backing up virtual machines is described in Acronis Backup & Recovery 11.5 and Acronis vmProtect: Backup Algorithm on ESX Environment article.
