True Image 2013: cannot backup from a network share to the cloud

Hello,

I have read a similar post for the 2012 version where you could not select the share at all. I can check it in the 2013 version so I assume it's supported now.

See attached screenshot: I use "Online backup", check a network share on a NAS (QNAP hardware, I can't install True Image on it so I'm trying to backup the contents from my PC)

It can compute the size so it can see the files.

I click on "Backup now" and I get this error immediately:

The specified files or folders do not exist.

More information about this error and solutions may be available online in the Acronis Knowledge Base.

Using TI 2013 to backup my PC disk image to a network share on the same location works fine.

Thanks for any hint !
