Cobian Backup : Couldn’t Create The Destination Directory

I’m a fan of Cobian Backup, the best FREE backup software that I’ve tried. In fact, I’ve been using Cobian Backup for the past 7 years already!

However, when I upgraded the software this morning, I encountered a problem wherein the program can’t create the destination directory. The destination directory is located on another PC but connected on the same network. When I tried to write a file using Windows Explore onto the directory, it was successful!

What could be the problem? How can I write using Windows Explorer while Cobian Backup 10 can’t? It’s actually on Windows permission rights. The Cobian Backup I installed is setup to run as a Windows service. Almost all Windows services are using the “Local System” account. However, the other PC won’t let the “Local System” account to access the directory.

What are the possible solutions? 

First make sure you (or the Windows user) have the required access rights. You can easily test this by going to the destination directory and copy a file there.

Second, change the installation mode of Cobian Backup from service to application. The reason? So it won’t use the “Local System” account.

How do you change the installation mode?

There’s no need to re-install the software. All you have to do is open Cobian Backup (by the way, I’m using Cobian Backup 11 Gravity version). From the top menu, choose Tools>Options. Click on the Service and Application Control button which can be found in the middle.

Cobian Backup 11 Option

Let the Windows User Account Control run the control.

From the Cobian Backup Control Panel, choose Services, then click on Uninstall. This won’t uninstall the software but only uninstall the Service from the Registry.

Cobian Backup Service Installation

Wait for some few seconds, and if the uninstallation is successful, the Cobian Backup then will try to write on the destination using your rights as user instead of the “Local System” account.

  1. It worked! Thank you for the instructions, and thank Cobian to made it easy to change from Service do Application without reinstaling the software. It is indeed the BEST backup software!
    [using Windows 10, Cobain Backup 11 and WD NAS 3T]

  2. thansk for the solution, i had the problem with the wd cloud hdd, i was able to run the backup only on the public folder, but when i remove the public and wanted to share as private, using the nfs service, cobian was not able to create the folder, even with all the rights on the user, i was able to browse the folders with windows explorer, but not able to make cobian do the back ups, thanks a million for sharing the solution,
    God Bless you, and yes, COBIAN KICKS ASS

  3. I had the same problem with a daily scheduled incremental backup, but Cobian was already configured as an application and not a service. I thought maybe there were too many folders on the backup drive, so I deleted one, and emptied the recycle bin, but that didn’t work. I made another task to do a full manual backup of the Documents folder, but that also failed. So I decided to change the backup to a USB thumb drive E: instead of my 2 TB external hard drive. It showed that it was working, but I had changed the target on the wrong task, and it was actually working on the external drive. I changed back to F: and I just manually performed the incremental backup. I had not changed anything since the full backup, so no files were copied, but it did create a folder with many empty sub-folders. I don’t know why that fixed it, but it seems to work once again.
