If you're just looking for a simple backup solution, I've had good results with creating a full image of the SD card/eMMC before making major changes. It's easy to restore if something goes wrong. For regular backups, syncing just your important configs and data is usually a lot faster than backing up the entire system every time.

I'd also check that the RDP service is actually running and listening on the expected port. If SSH still works, you can verify the service status and firewall rules from there. That usually helps narrow down whether it's an RDP configuration issue or a network problem.

One thing that helped me in a similar situation was checking that the running kernel version matched the headers exactly with uname -r. A mismatch there can be really confusing. If you've recently upgraded the kernel, a reboot before installing the headers is worth trying too.

I usually make a quick backup before running bigger updates, especially on systems that are already working well. It also helps to reboot after the update and check armbianmonitor -u if anything seems off afterward. That can provide useful information if you need to troubleshoot.

If Windows can see the share but has trouble connecting, it's also worth checking the SMB version being used on both sides. I've run into cases where enabling the correct SMB protocol or recreating the saved Windows credentials fixed the issue right away.
