I was doing incremental backups for the last three month, and now when I needed it most, Acronis came up with a message that it can not validate my backup archive. Low and behold, I tried to make another backup of my current windows installation disk and once again, Acronis says the backup is corrupt right after creation of the backup. I have ZERO idea of what is going on and I am really MAD. Few additional info:- Backup was always created outside Windowz environment, that is teh PC was booted from restoration CD. The first full backup was verified rigth after creation, later incremental backups were not. Latest fullbackup was verified right after creation. Backups are stored from day 1, in an external firewire hard drive. So far, I have not seen any sign of data corruption any any other files located in the same drive. What to do now?
