I am trying to set up a backup from my NAS (QNAP TS-469 Pro) to my PC running Ubuntu 16.10, using the "Backup Station" offered by the NAS.
If I ssh to the NAS and run the following commands, the rsync works:
touch file.txt # Create "file.txt" on the QNAP
rsync file.txt username@ipaddress:~ # Backup "file.txt" on the backup PC
However, when setting up a backup from the GUI of the NAS (in a browser), I get the error
Invalid port number or the service is disabled.
I read some things about port 873 or running a rsync daemon, but all this is very unclear for me.
Why does running rsync
manually works, while I get an error with the "Backup Station"? Of course in the end, I am interested in making the automatic backup work.
