This is not the last created volume of the backup archive. I have 8 Acronis True Image 9.0 .tif archive files available, but I apparently am unable to restore because the message "This is not the last created volume of the backup archive" shows up on each of the 8 files. The data in these .tif files is very important. Is there a utility that can extract whatever data is in those 8 files? Or, can the files be sent to Acronis and extracted?
