New Features

Universal VM Backup: This new agentless feature allows you to protect and restore virtual machines that are running operating systems not supported by Datto's standard agentless or agent-based solutions.

You can protect the following types of systems with Universal VM Backup:
- VMs with operating systems that Datto does not currently support via other methods.
- Less common VM appliances where the OS or filesystem are unknown, such as the following:
  - vCenter
  - VoIP systems
  - Security appliances
  - Network Appliances
In a disaster scenario, you can restore a Universal VM Backup to your ESX hypervisor by using either the Virtualize via Hypervisor or Export Image restore options. This feature requires a connection to the VM's host hypervisor.

Agentless backup logging

You can now access logs for agentless system backups directly in the Datto device UI just as you would for agent-based backups. You can use these logs to monitor backups and troubleshoot errors.

Improvements

To improve supportability, we have enhanced logging capability for the Bare Metal Restore Utility.
Offsite synchronization times are now staggered and will vary by device. This change will improve performance by reducing the number of devices sending offsite simultaneously.
