TerraMaster Forum

Applicable versions:
TOS 5, TOS 6

Applicable models:
All TNAS models

Operation guide:
1. First, please ensure that the source TNAS has successfully installed and enabled the client program (DupleBackup), and the target TNAS has also correctly installed and enabled the server program (DupleBackupVault).

2. Next, perform the necessary port mapping on the target TNAS to ensure that port 7922 is open.

3. In the source TNAS, select "Remote TNAS Task" as the target to create the backup task. When establishing a connection, please accurately enter the public IP address/domain name, user name, and password of the target TNAS to ensure that the connection is successfully established and the creation of the backup task is completed.

I think TerraSync also can achieve mutual backup between two TNAS located on different network .

If it helps, I have three NAS, each one I use the 2nd NIC as a backup network. So I can run rsync or whatever using the 2nd NIC. Oh yeah two of the NAS are the same network and the third one is on a different one.

If you can reach your remote nas with WebDAV protocol, tfm backup can do it

I have three devices, sig has the details. Two are on Network A and one is on Network B. A has it's own network switch, same for network B.
But I use NIC #2 on each as the private "backup" network for the lack of a better name. The backup network has it's own switch as well.
Network A and B each have internet access, while the backup network only exists between the three devices.
So any rsync or whatever tool I just using the NIC #2 addresses.
Oh all are 2.5ghz.
