I am attempting to connect to a DLink NAS that only supports SMB 1.0. Compatibility mode is enabled but I am still unable to connect. When exploring other options, I will try to make a change in the container.

host: 10.0.1.3 share: Volume_2 target_dir: hassio_backups username: REDACTED password: REDACTED keep_local: all keep_remote: all trigger_time: "00:00" trigger_days:

• Sun exclude_addons: [] exclude_folders: [] compatibility_mode: true

This may also be a limitation of the NAS. I assume the setting would have to be changed there but may not be possible.

This is indeed an issue with the NAS I have. It is an old DNS-323 I want to use as an offsite backup for disaster recovery. The workaround here is to update it to Alt-F firmware which not only provides samba 2.0 support but GPT as well. Perhaps there should still be more compatibility options for Samba 1.0.

This falls into the same category as the error that the server does not support extended security as mentioned in the FAQ --> https://github.com/thomasmauerer/hassio-addons/blob/master/samba-backup/DOCS.md#why-do-i-get-this-error-at-startup-server-does-not-support-extended_security

This is a problem with the supported authentication mechanisms of your NAS. Unfortunantely, LANMAN is old and outdated.

Got it, thanks. It is actually working now with Alt-F. Samba 2.0 support was the fix.
