Why saving an image to a mapped drive may sometimes fail

This article applies to:


If you schedule a task in an Acronis backup product to save an image to a mapped drive, you may find that the operation does not succeed sometimes, and sometimes it does.


When you map a drive, it becomes mapped only under your Windows account. The Acronis product runs its tasks using the system account and so it is sometimes impossible to locate your mapped drive (especially when you are logged off).


Please use a full UNC path (e.g. \\server\share\) instead of a mapped drive.
