Recently, our backups went from taking 2 hours to taking 8 hours. Nothing has changed in the amount of data being backed up. The only change is upgrading from SQL Backup 4 to SQL Backup 5.1. I'm not sure that is the problem, so I was wondering if there is any perfmon counters we should add to monitor SQL Backup and SQL Server, or if SQL Backup had any advanced logging that we could enable. We are running SQL Backup 5.1 with SQL Server 2005 SP2 x64 on Windows 2003 SP2 x64.
