Thecus N3200XXX NAS Server ReviewNemo - October 6, 2011

You can back up the data on the N3200XXX to another device using the Rsync synchronization utility. You can also back up the system configuration stored on the disk on module (DOM).
The disk on module (DOM) contains the system configuration information and you can have the system automatically back up the information daily at 1:00 AM. You can alternatively choose to establish your own daily, weekly or monthly schedule and the system will store up to five versions of the configuration files. You can also kick off the backup manually if needed. Unfortunately, the documentation is fairly useless on this subject and doesn't tell you where the backup files are stored, so using these to restore to a previous version may be a moot point.
Rsync Target Server
You can establish the server as a Rsync target in order for other NAS devices to back up to the server using Rsync. You must click on the Enable radio button and enter the user name/password combination the source server needs to use to authenticate. The final step is to hit the Apply button and confirm the changes.
Rsync is a backup utility you can use to synchronize files to another storage device accessible via the network or Internet. The first step is to click on the Add button to create a new task. The task name is pre-filled with a generic name and you can change it if desired; you can also add a task description. Rsync supports two backup modes – Synchronize and Incremental. With Synchronize mode, the source and target will match exactly, so if you delete a file from the source server, it will be removed from the target server as well. As you can see, there could be drawbacks to this method if you accidentally erase a file on the source. Incremental mode backs up new and changed files and does not delete files on the target if they are removed from the source. You can then specify the source folder(s) to back up by clicking on the 'Select source folder' and highlighting them. The target server is identified using a destination IP address and port number (873 is the default port for the Rsync utility). Note that the IP address could be a fully qualified domain name on the Internet. You also need to specify the destination path, which consists of a folder/sub folder name. You will need to specify the login credentials on the target server and a log folder to store the results of the backup. You can use the Test Connection button to verify you can connect to the target server. Finally, you can enable the task and set a time for it to run. Hitting the Add button adds the task to the task list and you can monitor the job in progress as well as check on the status of the last backup run.
During testing, I was able to successfully use the Rsync utility to back up to a Thecus N4100PRO NAS server on the network through port 873 as shown in the screen shots above. I was disappointed to see there was no capability to choose to back up to a legacy NAS server as there has been in prior versions of the firmware (this feature was available in version 3.04.03 and earlier). I tried changing the port to 21, the default for FTP, but it would not connect to the FTP server. There is also no way to manually launch a backup, another feature available in earlier versions.
That finishes the backup features and it's time to look at the last configuration section on external devices.
