Affected PVA Agent versions:

  • 6.0-2152
  • 6.0-2160


In order to create a backup, the list of devices is passed to Acronis libraries. Not all devices are recognized properly, and compound devices (like ones available through a multipath connection) are not processed during backup operation.

The issue has been reported in the internal request PVA-33996 and it will be fixed in one of the future updates.


Issue was fixed in the PVA 6.1 Update 1 (6.0-2695) - check release note

Update PVA Agent to the latest available version and backup will be created successfully.
