I have backup my VMware host with Acronis Backup 12,5. Backup scheme my host is weekly full+ daily incremental. But my virtual machines' (10 virtual machine) that in my host, backup schema is set to "always incremental" and I can't change this, to full or differential. When I try to create new backup job, and it cannot be changed. Can I change my virtual machines backup type to full or differential, thanks...
you'll need to change the backup format to a legacy one (format 11), see https://www.acronis.com/en-us/support/documentation/AcronisBackup_12.5/#38763.html Create a new backup task for that.
