Backing up Windows Server 2012 to a ReadyNas3100 share

[siliconaut]

Hello everyone,

as stated above, I run into trouble backing up Windows Server 2012 to a share on an older ReadyNas 3100 Business Edition. I have no trouble accessing the share via windows explorer, but the Windows Backup Assistant always breaks off when trying to configure a scheduled backup. 

The error message says that the local computer cannot recognise the username used for the remote share, even though I have used the correct username and password. Could this be an SMB 2.0 related problem and is there a solution? Since they're employing two 3100s, I'd rather not tell my client to thrash them...

The firmware currently installed is RAIDiator 4.2.15.

Any help would be very much appreciated!

FWIW I have seen posts on issues with Windows backup on 2012 server and Windows 8 on other forums also.

4.2.30 is current.  4.2.15 was released in 2010.  I'd try upgrading one of the NAS first.

One workraound is to use an iSCSI LUN instead of a share for the destination.

try smb 1 ran into this while back and I forget exact steps to correct but was smb related on both nas AND server.

iirc there was also local security policcy change on server to edit

It seems to be a part of the problem - I finally figured out a solution that works for my case:

Windows Server 2012:

1) Show status of SMB protocols via powershell: 

    "Get-SmbServerConfiguration | Select EnableSMB1Protocol, EnableSMB2Protocol"

2) If SMB1 is not enabled:

    "Set-SmbServerConfiguration -EnableSMB1Protocol $true"

3) Important: Add the user that the planned backup is run with (in my case, the Server administrator's credentials) on the ReadyNAS with the appropriate rights (user and password must match the one on the server, lowercase and uppercase seem to matter)

After this, backups planned via Windows Server Backup no longer throw up errors and the nightly backup to the NAS works. Hope this helps others who run into similar problems with SMB.

You can try again. In Available App list, installed SMB plus add-on and selected SMB 2.0, then Restart NAS.

Amidala, thank you for your input; unfortunately, we're talking about an outdated version of RAIDiator and I guess there is no "install apps" feature here.

even if it was available to the user smb2 could still cause errors on server 2012.

this is vista based server, smb 1 works.

most of config needed on server end anyways.

on server 2012r2 smb2 does work, also server 2012r2 essentials works with smb2.

I have not tested with server 2008r2 or sbs2011 based on 2008r2 but I think smb2 would work.
