general discussion
1

Hello,
I have NAS with installend UrBackup Server (debian) and PC with Windows and I can install UrBackup Client on this PC.
I need to back up the data from NAS to HDD in PC with Windows, it’s also possible to configure it?

Install Client package on NAS and Server Package on Windows PC.

On the one hand, the NAS does not directly support the UrBackup client.
And especially on NAS I have access from the Internet and I do not have access to a PC, I am looking for a solution that would primarily run on the NAS and its functionality to check on the NAS

What is the OS on the NAS ?
Can you mount NAS share on Windows System ?
