Hi, this is my first post and i really really need help on that issue. here are the details:- I created an image of the C: drive multiple times every 6 to 8 months of my Toshiba laptop since 2010. Suddenly i lost all the latest archives and i have left with one created in January 2010. ( i dont remember which version i was using back in january 2010 ) I bought new Toshiba laptop, and then try to restore the image but when it reaches only at 430mb, it says invalid archive file. i try to recover the image on several different laptops/desktops but the result is same at 430/432Mb (invalid archive file). the file is 15GB normal(four files of 4gb) image backup file. I did the integrity check and same on 430/432MB it say invalid archive file. How can i resolve this issue . if by any means its not possible than at least i need to extract few files from this archive.
