Setting up an Nsync Target on an Thecus IP storage Nsync Device
On the Nsync target server, the administrator of that server has to set up a user
account with a folder named “nsync” and grant write access.
1. On the Nsync server, add a user for Nsync source (ex. nsyncsource1). For
instructions on how to add a user on the Thecus IP storage, see Chapter 4:
User and Groups Authentication> Local User Configuration > Add
Users.
2. On the Nsync server, grant that user (ex. nsyncsource1) write access to the
nsync folder. For instructions on how to set up a folder’s ACL, see
Chapter 4: Storage management> Shore Folder> Folder Access
Control List (ACL).
3. Once this is done, the target server will start accepting Nsync tasks from
server using that ID and password.
Setting Up an Nsync Target on another Device other than Thecus IP
storage
If you selected “Legacy FTP Server” when setting up your Nsync task, the Thecus IP
storage will use the FTP protocol to back up the share folder. On the external storage
device, make sure there is a folder named “nsync”, and the Auth ID has writable
permission in that folder.
Designating Thecus IP storage as an Nsync Target
The Thecus IP storage can act as an Nsync server, enabling another Nsync-equipped
Thecus NAS at a remote location backup their files to this Thecus IP storage. From
the System Network menu, choose the Nsync Target item, and the Nsync
Target Server screen appears.
Nsync Target Server Setting
Item Description
Nsync Target Server Enable or Disable Nsync Target support.
Dual DOM (except N0503/N4200Eco/N7700/N8800)
The unique Dual DOM feature can now perform “Auto Repair”. The Thecus NAS will
backup up to five versions of the system configuration either by the default timing of
1:00am every day automatically or as scheduled by the user.
This unique “Auto Repair” will be triggered if the primary DOM has a booting issue.
In this instance, the 2
nd
DOM will take over the boot function. Then, the system will
automatically load the most recent system configuration backup image to repair the
primary DOM.
NOTE
To enable Nsync task to go thru firewall, you have to open port TCP/1194 on
your firewall in both directions.
