Archive for the ‘Transaction Logs’ Category

This is really one reason why I don’t like the built in maintenance plans. Why can’t they simply ignore the databases which are in simple recovery mode? Why do they instead fill the error logs with message that they have tried to backup the transaction log of the master database??

I wanted to be able to choose which databases to exclude – and then only try to carry out a T log backup on a DB which has Full or Bulk-Logged recovery set.
Remember you can only start T Log backups after you have taken a full backup.
