Data Encryption via WebDAV

Hi everyone,

I have a question about how backups are handled on the UGREEN NAS, especially when using WebDAV or RSync to a remote storage service.

If my data on the NAS itself is not encrypted, and I create a backup task that uploads data to a remote location – is the data stored encrypted on the remote side, or is it accessible in plain form?

I also didn’t see any option in the Backup & Sync app to configure client-side encryption or to set an encryption key. So if the data is encrypted remotely:

• Where is the encryption key stored?
• Can I export or back up the key?
• What happens if my NAS fails — will I still be able to recover and decrypt my backup data?

I just want to be sure that my off-site backups are safe and still recoverable even if the NAS itself becomes unavailable.

Thanks in advance for any clarification!
