We are having intermitten failures in backing up the transaction logs. We are running SQL Server 2005 Enterprise with SP 4, working on testing migration to SQL Server 2008 R2.
10pm we perform a full database backup.
11pm the transaction log is truncated with backup log <database> with no_log, and DBCC shrinkfile is run.
10am the next day, the transaction log is backed up.
My thought is that the 11pm transaction log truncation and shrink job is the problem; if the transaction log trunaction is the problem, then why does the 10am transaction log backup succeed in most cases?
Any assistance would be appreciated.
