Need Cross NAS BackUp Solution

[Pegasus9]

After the Duplicati (via Docker) method to restore from a backup on a WD PR4100 NAS OS5 to my uGreen NAsync turned into a several hour job, I am back to looking for backup software.

My setup is easy, I wanto to use my WD PR4100 NAS OS5 (on my network with shares available) to back up my uGreen NAsync DXP4800 Plus. The WD can handle port 22 ssh transfers if I need to do it that way. I have connected the network drives on my WD to the NASync. The native backup software, of course, will not go to any other OS but it's own and rsync from the WD says ther are permission issues, but I have it wide open to my network to test.

I keep hoping they will add crossover capability but I haven't seen it yet and I need something. Any ideas?

It looks like the Ugreen is just another Linux os. So all you have to do is create a service account with the group root.
The account you ssh with must have root privileges.

Thanks for your fast response, yes the uGreen is based in Linux and most things work fine that way. After several more hours of play,

I was able to set up an SSH on the WD, and I can even get the backup program on the Ugreen to access it using the rsync/ssh so I can see all of the shares. However, when I tried to access the share it tells me it lacks permissions or the path is not found. I'm not sure how it could be the path when I'm see all the shares- so it must be permissions. The permissions on the share are set at read/write for anyone.

What I really don't understand, is how Duplicati was able to use SSH to log into the same location without issues, but using the exact same login information I am not able to get there from the UGreen app.

Admittedly, I am not a UNIX/Linus power user, but this all seems like simple stuff that is tripping me up.

There are a few ways they can write the program, but I imagine it just reads the samba config file for mounts.
If you are SSH into it as a root user, you have root access. So you need to know the actual mounted path instead of the samba share path if doing rsync via ssh.

So when you do something like syncing the directory tree:

rsync -av --delete /local-path/ username@servername:/remote-path/

/local-path/ might be /home/user_name/Documents/ while /remote-path/ might be /usr/share/samba/samba_share_name/ even though its advertised as //hostname/samba_share_name

I appreciate yoru response and efforts. After spending a week on this and dealing with uGreen, I am abandoning the effort. It simply cant be done with exisitng tools and propriety OSs. I bought another uGreen server and I m going to give the WD to my son.
