Backup Netgear RD5200

Hello,

We have a Netgear RD5200 NAS with several CIFS shares. The NAS is registered in our AD.

When we try to make a backup of those shares, the TSM client fails and shows these errors in the logfile:

I am 100% sure, the TSM client can read/write the share and the folders/files.

We are using TSM server 5.5.5.2 and TSM client 6.4.0.10.

Does anyone know how to make a backup of CIFS shares on this Netgear RD5200 NAS?

Thanks in advance.

Best regards,
