I was using PGP WDE Desktop and had no problems backing up with Acronis True Image Home 11, build 8101. I recently added a NAS and PGP Enterprise NetShare (9.9.1, build 287). I scheduled the backup task and was able to run it until last week. Now, the task will start, I can see it accessing and backing up the files, but part way through a message pops up that the instruction could not be read and the operation was terminated. This is not the same as an access denied message, where PGP is not allowing Acronis to access the encrypted data. Instead, the backup begins and then terminates. I ran the backup several times and the termination point is never the same (once it was almost through the entire backup). If I decrypt the folder, the backup runs without a problem. I am running Windows XP Pro, SP3.
