    Robocopy backup to NAS does not work : "Access is denied"


    I'm trying to backup a directory on my laptop to my NAS with a script :
    robocopy D:\Videos "Z:\Shared Videos" /MIR /XJ

    When I run the script, I get the error message "Access is denied." However, in the File Explorer I can drag-and-drop files to the NAS. Also with iPhone and iPad no problem to access the files on the NAS.

    How can I solve this ?

    :)

  2. Copy NTFS permissions to a NAS with Robocopy

    Hello,

    I'm actually using Robocopy to copy a "home" folder with NTFS permissions to a NAS Synology. All theses equipment are on the domain, that will be named XXXXX in this post.

    The permissions on the "home" folder are explicit, and not inherited from the parent folder. Also note that the SYNOLOGY NAS have the Windows Permissions activated.

    The goal is to create a backup of this "home" folder to the NAS with the permissions.

    Here is the Robocopy script that i'm using :

    ------------

    set rep_log=C:\Script\log

    set rep_sync_DATA=\\SRV1\e$\home\

    set rep_sync_NAS=\\NAS-SYNOLOGY01\test01\backup\home\

    robocopy %rep_sync_DATA% %rep_sync_NAS% /MIR /SEC /ZB /NP /XF thumbs.db /R:2 /W:5 /log:%rep_log%\Synchronisation_backup_nas.txt

    -----------

    The Robocopy script works well, and the files are well copied. EXCEPT one. On my "home" source folder, we can find on the permission list the XXXXXX\Administrators group. (explicit permission)

    But, unfortunately, once the folder is copied to the NAS, it change the XXXXX\Administrators group to NAS-SYSNOLOG01\Administrators. This folder take the local domain of the NAS instead of my AD domain.

    Please note that this "domain change" is only applied to this group, and the others lambda groups are not impacted by this strange change. (example XXXXXX\Sales group on source folder will be copied as XXXXXX\Sales to the destination)

    The same script works perfectly if the destination is a USB HDD for example. It only happens if I want to copy to the NAS.

    Any idea to fix this issue ? I faced this issue twice, with SYNOLOGY and with NETAPP technology. Whatever soft I tried to copy (robocopy or others), the result is the same...

    Thanks for your potential help Robocopy backup to NAS does not work : "Access is denied" :)

  3. Lumia " The Future is Here "

    This is a support forum, not a complaints department.

    I suggest you directly submit your complaints about hardware to Nokia and software to Microsoft.



    Also it often helps to read reviews when switching platforms to make sure it suits your needs. From what you've said the Lumia 820 clearly doesn't suit you.
