No, I think I didn't explain this exactly. What I meant is that Acronis has an option to split the .tib images in different sizes (e.g. CD-ROM size, DVD-ROM size) when a backup is created. With such .tib files it is possible to burn each of these files on a CD/DVD (or create an ISO image) using a CD-ROM burning application, then boot the VM from the Acronis boot image and restore from the ISO images (you may need to temporarily add a second virtual CD-ROM for this, i.e. one for Acronis and one for the images).
