A connection with a NAS over the Internet will be slower compared to a LAN 
environment.  
As you switch back to a LAN-based NAS, ensure that you reconnect to the NAS via LAN 
to get a better connection quality.  
To improve file transmission performance, it is recommended that you configure port 
forwarding on the router.

Version Control 
 
This will retain one copy of a file as a version whenever you add or modify it, allowing you to 
retrieve a specific previous version at any time. Or, if you accidently overwritten a previous 
version made by others while editing the file in team folder, you can still restore the 
previous version. And you can restore the previous versions even if you have deleted the file 
from the recycle bin. 
 
Viewing the version history  
You can view the version history by using File Station. Right click on a file or folder in the 
Qsync folder in File Station and select Previous Versions to show the version list (or you

Click Delete All to delete all of the listed versions. 
Click Refresh to update the status of the version history. 
 
Restoring versions of a deleted file 
Version control retains versions in a separate location, so even you delete the file, you can

recycle bin.  
To restore the version of a deleted file, click on any folder/file in the Qsync folder, and then 
click More Action > Show Deleted Files in the menu bar. To view the version history, 
right click on a file/folder in Qsync folder and select Previous Versions. Or you can access 
it from the menu bar, More Action > Previous Versions. Or just click the Show Right 
Panel > version to show the version list. 
 
Restoring previous versions

Managing and setting version control  
To access the management and settings of version control, click the Qsync button on the 
desktop of the NAS, then click Version Control in the right-side menu. 
 
The target folder  
Enable version control is the main switch of the version control. Disabling this option will 
not delete versions that have already been created. Enable version for my Qsync folder 
allows each user to apply the function to their files.  
						

							295 
 
  
Target folder for version control 
You can apply the version control to the files under specific Qsync folders to save space. To 
assign specific folders, select Assign specific subfolder under the Qsync folder, then click 
Add to add folders. You can add up to 5 folders. Click Delete to remove all versions 
under the selected folders and subfolders. This will not take effect until you click Apply or

Advanced  
Maximum Number of Versions: You can choose how many versions you want to retain. This 
is a control only for administrators. The more versions you keep the more storage space will 
be taken up. To know how much space has been used for version control, click Check in 
the Disk Used for Version Control section. 
 
Note:  
If you reduce the maximum number of versions, it will impact the versions that have 
been created and if the volume of versions exceeds the new settings, the earlier 
versions will be dropped. Only the equivalent number of latest versions as of the new 
settings will be kept.  
The deletion will only take effect after you click Apply or Apply All. 
The maximum number of versions supported for Version Control is 64.

SQL Server 
 
You can enable an SQL Server to be a website database. 
 
 
Note: For legacy ARM models (TS-x21, TS-x20, TS-x19, TS-x12 and TS-x10), MySQL will 
still be used as the default SQL server. If you are using a legacy ARM model, you can still 
install MariaDB from the App Center. 
 
Enable TCP/IP Networking 
 
You can enable this option to configure MySQL server of the NAS as a database server of 
another web server in remote site through Internet connection. If this option is disabled, 
your MySQL server will only be configured as a local database server for the web server of 
the NAS. After enabling remote connection, assign a port for the remote connection service 
of the MySQL server. The default port is 3306. After the first-time installation of the NAS, a 
phpMyAdmin folder is created in the Qweb/Web network folder. You can enter http://NAS 
IP/phpMyAdmin/ in the web browser to enter the phpMyAdmin page and manage the MySQL 
database. 
 
Database Maintenance 
  
						

							299 
 
o Reset root password: Reset the password of MySQL root as admin. 
o Re-initialize database: Delete all the data on the MySQL database. 
 
Note:  
To use this feature on the TS-x39/509/809 series NAS, please update the system 
firmware with the image file enclosed in the product CD or download the latest system 
firmware from http://www.qnap.com. 
Do not delete the phpMyAdmin folder. You can rename the folder but the link on the 
MySQL server page will not be updated. To connect to the renamed folder, you can 
enter the link http://NAS IP/renamed folder in the web browser. 
The phpMyAdmin folder is created after the first-time installation. When you update the 
firmware, the folder will remain unchanged.

NTP Service 
 
A NTP Server allows the PCs, servers and other network devices to synchronize their time with the 
same reference: the NAS. It is useful (and sometimes required) to keep the time synchronized for all 
devices in some environments. 
 
 
Setting up NTP Server 
To set up the NTP Server, first go to Control Panel > Applications > NTP Service and check 
Enable NTP Server. Select to check the following three operating modes: 
Broadcast: This will allow the NTP server to periodically send broadcast packets with the IP 
address 255.255.255.255 . Clients compatible with this mode can use this to synchronize their 
time. 
Multicast: This will allow the NTP server to periodically send multicast packets. Clients compatible 
with this mode can use this to synchronize their time. Specify the multicast IP address after this 
option is enabled. 
Manycast: This will allow the NTP server to listen for manycast requests from NTP clients and 
reply to the client requests received. Specify the manycast address after this option is enabled. 
 
Note:   For multicast and manycast modes, the NTP clients will only receive this kind of 
packets after they are configured for the modes. Please refer to their user manuals for 
setup details.
