You can convert .tib backups from Acronis to VHD format (Virtual Hard Disk) right inside the Acronis TrueImage utility. In order to do this, install the software and follow these instructions:
- Run Acronis True Image. Click Tools ► Convert Backup to Virtual Disk
- Conversion to Virtual Disk Wizard will start
- Select the backup archive that you will convert to .vhd format
- Select Microsoft Virtual PC
- Specify the location where you would like to save the .vhd file
- Click Proceed to start the conversion
- Conversion will start
There is likely no other way to convert tib to vhd, so using Acronis software is your only option for tib to vhd conversion.
