I've been using Acronis 11 to backup my C drive once a week for a year. Today my Vista went berserk and I'm told it's corrupted and I have to reinstall it. I laughed at them. It's okay, I said, with a smug smile. I've got an Acronis backup of my "C" drive. That is, I thought I had. Background. Newer comptuer. My Vista OS is there but many of the functions are not working (eg. can't access "personalize" or Internet, etc.. Definitely corrupted. I opened my Acronis from the desktop and clicked on restore. I selected one of the incremental .tib backups and everything went along fine until i went into the final restore. The Acronis started analyzing my "C" drive then stopped and gave me the error message "The Archive is Corrupted. I tried again manyl times. using different .tib dates, but the result was always the same. I did a forum search for information about corrupted archives, but I couldn't find anything to help me out. In fact, I couldn't understand most of it (Snr. Citizen, not very computer literate) I've submitted a request for help, but have not heard back. I'd sure like to know what's going on. My Acronis is right up to date and I expected it to work. To say I'm disappointed is a very faint reflection of what I'm feeling right now. I work on my computer and it's all set up for what I do. I'd hate to have to reload the OS and all the programs. Any suggestions to get me out of this mess?
