I am recently using trial of TI11 on Vista. Unfortunately I've ordered a boxed version before I found this problem, and from the looks of the skimpy support, I feel I may have just lost my money. I sent a message to Acronis support about 6 days ago, of course no reply as I had expected after reading the posts here. The problem : At first everything was fine. I created a Secure Zone on my main drive, as partition drive D. I created a full backup. I created several incremental backups. I took the plunge and even restored to a backup just to test it (I realize now how serious a mistake this was, and how lucky I am that it worked). But the restore did work fine, I made more incremental backups and mounted them, all good. Then all of a sudden, when I try to mount the SZ, I get a message that says I have no backups. So 1) what changed 2) any idea how to correct 3) if it is uncorrectable, can I just re-create a full backup over top the so-called non-existing backup? I also tried the Try-and-decide, what nightmare of hangups and errrors, but thats a whole other thread I guess. Thanks to anyone who may have a suggestion, as I don't expect anything from Acronis at this point. How dissappointing. As a side note, I think it would be great to get recommendations on other products that are reliable, perhaps a link to reviews. I'd be willing to chalk up my money as "live and learn", yet again.
