Hi, I’m running Dietpi 6.22.3 on an Odroid XU4. I used dietpi-drive\_manager to mount a NFS Share on a Synology NAS. When I run dietpi-backup, it failes. Here is a excerpt of the output: ```nohighlight du: cannot read directory '/mnt/nfs_client/volume1/Backup/FHEM/dietpi-backup/data/home/dietpi': Permission denied du: cannot read directory

The backup has never be run before. Regards Oli ---

OliS. Does the file system on the Synology support UNIX permissions? Try to place a test file on it and apply permissions: ```nohighlight > /mnt/nfs_client/volume1/Backup/FHEM/test chown www-data /mnt/nfs_client/volume1/Backup/FHEM/test chmod 775 /mnt/nfs_client/volume1/Backup/FHEM/test ```
