In some circumstances, after an upgrade from Backup Exec 2010 R3 to 2012 Sharepoint backups fail with logon error
In some situations, depending on the pre-upgrade license status of the Sharepoint agent, after a successful upgrade from Backup Exec 2010 R3 (and possibly R1 and R2) Sharepoint backups may fail without backing up any data. The error message is below.
0xe0009b61 - Backup Exec could not log on to the server with the logon account specified for it.
The logon account does not have valid credentials.
Ensure that the user name and password are correct in the logon account.
This issue has been encountered when upgrading a Backup Exec 2010 R3 environment where the Sharepoint agent was never licensed in Backup Exec 2010 R3 but was in a trial mode which had expired before the upgrade. With Sharepoint backups licensed in the upgraded version of Backup Exec 2012 with the Agent for Applications and Databases, the credentials for the Sharepoint farm resource do not seem to be passed correctly.
In the Backup and Restore 'Servers' view in Backup Exec, locate and remove the existing entry for the Sharepoint farm resource. Note that removing a server resource deletes all jobs associated with the server/farm. Once the farm has been removed, add it back in using these steps:
1) click the 'Add' icon in the menu bar and select 'Microsoft Sharepoint server farm' then click Next.
2) Check the box to allow Backup Exec to establish a trust with the servers then click Next.
3) Supply the Web server name for the Sharepoint farm, accept or modify the 'Server farm name' entry, and add a Server farm description if desired then click Next
4) Highlight the Sharepoint farm resource in the Servers list and create desired jobs.
