I am using Acronis 9.0 build 2,259. I am using a Maxtor One Touch external hard drive as the medium to back up on. I have been backing up for several months with no errors. Yesterday I tried to restore a file and found that it had corrupted the file. I program and my IDE gave me an error that a line of code was too long. When I scanned down the file I ran into the beginning of a string of little squares and no more valid text. I tried deleting the back up on the external drive and did a full back up. I got the same problem with that file and when I tried other files I got similar errors. I checked with the site and saw that there was a more recent build but the web interfacem, when I go to the screen for updating tells me there are no updates.' I also used the option to test the integrety of the back up and it said it "succeeded" after scanning it which I assume meant it was suppose to be ok. You can imagine how upset I am about not having a reliable back up. I have sent a message to Acronis and am waiting for a response. I need to address this ASAP. Any help would be appreciated.
