Incremental convert to virtual machine recovers only changes that were backed up since the last machine update: Acronis Backup and Recovery 11 updates the virtual machine instead of recreating it. This can be used during automated conversion of an incremental or differential backup to a virtual machine on a virtualization server.

This functionality is available for the following virtualization platforms:

  • VMware ESX(i)
  • Microsoft Hyper-V Server

To update the virtual machine, the software creates intermediate snapshots with names Backup.. and Replica... The latest Replica... snapshot corresponds to the latest conversion result and you can revert to this snapshot, if needed.

Intermediate snapshots are cleaned up automatically. If intermediate snapshots are deleted manually, it is impossible to update the virtual machine and the machine be recreated entirely instead.

Setting up incremental conversion

  1. Press Create backup plan on the start page of Acronis Backup and Recovery 11 and select the data that you want to back up and specify the backup location;
  2. In How to back up section, select a backup scheme with incremental and/or differential backups. Select Convert in Convert to virtual machine:

  3. In Convert to virtual machine section, select when to convert. To use incremental conversion, select After an incremental backup is created and/or After a differential backup is created:

  4. Click VM type. In VM//VS Selection window select Place on the virtualization server that I select and select a virtualization server from the list of servers that are registered on Acronis Management Server;

    (!) Incremental conversion to virtual machine can only be performed by the virtualization server. If you select to save the virtual machine files instead, virtual machine will be recreated on every conversion.

  5. In Storage select the storage on the virtualization server. If necessary, specify the virtual machine name in Resultant VMs.

When the backup runs, a new virtual machine will be created during the first conversion. Later conversions depend on backup type:

  • If a full backup was created after the last conversion, a new virtual machine is created;
  • If an incremental or differential backup was created after the last conversion, the existing virtual machine is updated with changes.

(!) Incremental conversion works only if the target virtual machine is turned off. If target machine is turned on, incremental conversion will fail.
