Symptoms

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.

Cause

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).

Solution

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

You can also use a pre backup command to mount the mapped drive for an Acronis scheduled task:

1. Download map.drive.txt;
2. Follow instructions in Using Batch Files in Acronis True Image.
