  • RE: Backup whole instance SQL Server 2008

    Reinforcing Thomas' answer. Backup every database on the server (except tempdb) and you've backed up the server. All the logins, etc., are stored in system databases. Capture those, you've captured...

    I can't explain the differences in the statistics (and I've reached out to some people to see if someone can). However, I can explain performance hits on failover. You're going...
