Tim Radney - Database Professional by Tim Radney I am a Sr DBA for a top 40 US bank. I live in the south eastern US. I have been working with database since 1999 but only full time for the past three years.

Know Backups and Know Restores – SQL Server Restores

A couple of years ago I put together a training session to demonstrate various types of backups and restores. The driving factor behind me building this session was the response I got from talking to a dozen or so DBA’s about disaster recovery. I asked how many have ever performed a restore where you had to apply transaction logs.  I expected everyone to raise their hand but I only had one person.  This was from a group where everyone was responsible for backup and recovery of their environment.

With something so simple I realized there is a big need for demonstrating these actions so that at least everyone is familiar with the process. I had to spice things up since performing backups and restores are not all that sexy. In my presentation I demonstrate traditional backups using full and log, then full with differential and logs, a file group level backup with piecemeal restore and finally tail log backups.

With the tail log backup I backup the tail end of the transaction log after deleting the data file as well as attaching a transaction log from a database on one virtual machine to a database on another virtual machine and still back up the tail end of the log.  This is always well received.

During my presentation I demo a set of scripts that I use to generate the restore script. I share that many have adapted these scripts to their production routines to generate their restore script after every backup. This helps tremendously for restore validations as well as production restores and could also be leveraged in your DR procedures.

I have included a download of my sample databases, scripts and presentation here >>> KnowBackups
