NV-NFS --> NFS backup failing due to permissions

I think I have found a workaround for this. It does however require that on the local NAS the add on "Enable Root SSH Access" (http://www.readynas.com/?p=4203) is installed:

1. Set up a user (e.g. john1) via Frontview on the local NAS with a uid corresponding to the uid of the user you want to use on the remote NAS (i.e. the user under which the backup process using rsnyc should run).
2. Set up a share (e.g. remotenas) via Frontview on the local NAS that will be used as mount point for the remote share.
3. Login as root via ssh to the local NAS.
4. Mount the share (e.g. /mnt/md1/test) from the remote NAS (e.g. 192.168.8.7) to which you want to back up to via NFS:

mount -t nfs 192.168.8.7:/mnt/md1/test /remotenas

5. Run rsync to back up a share (e.g. media) on the local NAS to the remote NAS:

sudo -u john1 rsync -v -r -u /media/ /remotenas/ 

After completion a copy of the content of the share media on the local NAS is in the share /mnt/md1/test on the remote NAS.

6. Unmount the share:

umount /remotenas
