Acronis TrueImage backup disk images (.tib) can be converted to VMware virtual hard drive format (.vmdk) with VMware vCenter Converter Standalone, but this works only on .tib files created by the Acronis True Image version 11, 10 and older.
To convert newer versions of TIB format, use True Image to convert .tib file to a Microsoft VHD format and after that Start V2V Image Converter to convert VHD file to the VMDK format.
You can find more detailed instructions in one of our articles called Run Acronis TIB as virtual machine (check the links).
