Is there a possibility to sync to a Qnap Device?
You can only do this if you have NextCloud running on QNAP and do port mapping to make sure it it accessible publicly. Below is a link to the QNAP forum where they provide a package to install it.
Since this is done outside of the NextCloud developers you will need to go to the QNAP forum for initial support.
Ok ty then i think i stick to rsync then^^.
What you can also do (which is how I do it) is create an external shared link to QNAP using SMB, that way all my files are synced via NextCloud onto my QNAP and stored with more redundancy than just a single HDD.
Just wondering now this thread is a few years old, if there are any new options available?
