Setting up the QNAP

On the QNAP, go to the “Remote Replication” page, and turn on “Allow remote Rsync server to back up data to NAS”. (“Enable backup from a remote server to the local host.” should already be set, and the port should be the default of 873)

Fixing rsyncd.conf

Unfortunately, there seems to be a problem with the rsync configuration file – the master user is set as “admin” which doesn’t exist (the root user on the QNAP is “administrator”).

To fix this, edit /etc/rsyncd.conf and change: -

uid = admin

to

uid = administrator

Listing Remote Folders

To check that rsync is allowing connections, go to your client and enter: -

rsync 192.168.0.2::

You should get something similar to the following: -

Qmultimedia
Qdownload
Qweb
Qusb
Public

Backing up a directory

To back up a directory, its a simple matter of issuing an rsync command. For example: -

rsync -vrltz –progress –password-file=password.txt –delete –exclude-from=excludes.txt “/cygdrive/C/users/windows_user/Documents/” “qnap_user@192.168.0.2::qnap_folder/“

where: -

password.txt is a file containing your qnap password
excludes.txt is a file containing files not to synchronize
C/users/windows_user/Documents is the folder to copy
qnap_user is a QNAP user that has access to the remote folder
192.168.0.2 is the IP address of the QNAP device
qnap_folder is the destination
