BackupAssist v4 and later

Description

BackupAssist cannot access your NAS device using the path provided, or BackupAssist is not authorised to access the NAS device.

Resolution

There are 6 possible resolutions for this problem

Solution 1 - Check for Multiple connections to a server or shared resource by the same user.

Microsoft has a limitation on multiple connections using a specific set of credentials.

The entire error generated when this limitation is reached is:Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again.

Things to check include:

  • The Backup User Identity
  • The Mapped network drives on the system
  • The Network paths in BackupAssist
  • Any user specified credentials on the Destination tab of the backup job.

Solution 2 - Ensure the backup destination is online and accessible

Make sure that the server hosting the network share is turned on and accessible within your network.

This can be checked as follows:

  • Browsing to the folder location in Windows Explorer.
  • Communicating with the backup destination using ping requests.

Solution 3 - Make sure the backup destination's path is correct

The server name in the destination setting for your job should not include any prefixes.

For example Server not \\Server.

The path on server should not contain the server name.

For example \backups\2007 not \\Server\backups\2007.

Destination : Network location

Solution 4 - Check the permissions to the network share

When accessing shares without authentication, you will still need to authenticate with the server / appliance hosting the network share if the shares permissions are set to Everybody or Everyone. This permission only means that all members / groups of that domain / server / device will be able to access the share.

To enable authentication free access, you will need to enable Guest permissions on the share, providing your backup destination supports this. In most cases, it is better to create an account or add specific permissions to an account, that will allow access to the share.

Solution 5 - Check the Backup User Identity's permissions

Check that your Backup User Identity has been set and has the required access. To view your current Backup User Identity, select the Settings tab > Backup User Identity and you'll see the following dialogue box appear.

Backup User Identity

Note: For BackupAssist 10.4.2 and earlier, the Backup User Identity is used for all backup jobs and the account may have been created with custom access levels. For 10.4.3 and later, a Backup User Identity is only required for Jobs that have a NAS destination or the SQL add-on, and in these cases, the Backup User Identity should be a member of the Administrators group.

What to check

  • For BackupAssist 10.4.2 or earlier - check that the account is still selected, enabled and has the required access.
  • For BackupAssist 10.4.3 and later, check that the account is still selected, enabled and a member of the administrators group.
  • To check the permissions properly, you can log into the backup server using the Backup User Identity account and check that you can read and write to the backup destination without any authentication requests or errors.
  • If backup account's password is changed in Windows, it will need to be changed in BackupAssist.

Solution 6 - Check the network share username and password configured

You will need to provide BackupAssist with account details for the share you are attempting to connect to.

To provide specific authentication for the network share:

  1. Open BackupAssist.
  2. Select Manage Backup Jobs
  3. Select the backup job.
  4. Select Edit from the top menu
  5. Select Destination from the options on the left
  6. Tick Network location requires username and password and enter the credentials required.

Destination : Network location

Solution 7 - Check NAS firmware and drivers are up to date

You should also check that the NAS drivers and firmware are up to date. The drivers and firmware will be available from your NAS vendor.

Note: The account specified here must exist on the destination domain / server / device, and this may be different to the accounts on your local server / domain. If no credentials are entered, then BackupAssist will use the Backup User Identity for authentication.
