Problems Backing TrueCrypt Image File Hello I have following Problem: I use a TrueCrypt Volume for my private Files. When I change the TrueCrypt Volume (which is physically a large File on my Harddisk) TI didn't make a incremental or a differental Backup in my Acronis Secure Zone, the Truecrypt Volume File is NOT Backed up, because I changed it. I copy a new File into it. Make a Backup and than I restore the truecrypte Volume File and my marker File isn't in There. Truecrypt didn't change the date and time of the Backup File. Has some one a solution for me to solve this Problem. I make at the moment only full Backups but this is not what I want.
