The following services must be installed on the client prior to installation of the agent:
• Volume Shadow Copy – Can be manual or automatic startup type.
• SQL Server VSS Writer – Should be started and set to automatic startup type.
• SQL Server Browser – Should be started and set to automatic startup type.
If the SQL Server VSS Writer or SQL Server Browser services are not started when you install the Windows agent, the agent will not pick up on the SQL instance. Installing the agent installs the BP Agent service. The SQL Server VSS Writer, SQL Server Browser, and BP Agent services must be running to perform backup and restore operations.
• SQL backups and restores are performed using the NT AUTHORITY\SYSTEM account. The NT AUTHORITY\SYSTEM account must be configured as sysadmin. Note that SQL Server 2012 does not grant NT AUTHORITY\SYSTEM sysadmin privileges by default.
• For SQL Server 2012, NT AUTHORITY\SYSTEM must be manually added as a system administrator. SQL backups and restores are performed using the NT AUTHORITY\SYSTEM account. For more information, go to the Microsoft knowledgebase.
