When attempting to connect to a User Defined share that is a Samba (SMB/CIFS) share on an NDMP server, Backup Exec reports Failed to log on to:


Failed to log on to:

Logon account: System Logon Account

Access is denied


If the server that hosts the SMB share has an NDMP server on it (NetApp for example), Backup Exec connects to the NDMP server (port 10,000) on the server and if that fails, does not try to connect to the share using SMB.

Backup Exec uses the default login to list and connect to User Defined Shares.  When connecting to a Samba share on a Linux server, there must be a Samba user on the server with a username and password that matches the username and password for Backup Exec's default login.  The default login account that is being used by Backup Exec can be seen by going to the Network / Logon Accounts ... dialog.  Look for the account that has "Yes" in the Default column.


Warning: User Defined Shares are not the preferred method for backing up data from an NDMP server.  Backing up using this method is only going to back up the data and some rudimentary file attributes.  It will not back up Linux file permissions.  The preferred method of backing up an NDMP server is using the NDMP Option.To backup User Defined share that is a Samba (SMB/CIFS) share or Shares hosted on NDMP device  only best effort can be provided by Technical Support


In order to use the SMB protocol to back up an NDMP server using a User Defined Share, the following must be configured.

1.  Create a Samba user on the that matches the username and password used in the default account with Backup Exec.  Note that the domain or workgroup for the username does not have to be used.  For example, on a media server in a workgroup, the System Logon Account is typically the default account.  Unless it was changed, the username for this will be something like SERVER_NAME\Administrator.  If this is the case, create a Samba user called Administrator and make the password match the Administrator password on the media server. 

2.  Stop the NDMP protocol on the server that is hosting the share.
