Summary Chapter 6: Log Restores After reading and working through this chapter, you should also be fairly comfortable with the basics of log restore operations, and in particular with point-in-time restores. The key to successful restores is to be well organized and well drilled. You should know exactly where the required backup files are stored; you should have confidence the operation will succeed, based on your backup validations, and regular, random "spotcheck" restores. You may be under pressure to retrieve critical lost data, or bring a stricken database back online, as quickly as possible, but it's vital not to rush or panic. Proceed carefully and methodically, and your chances of success are high. 204
Chapter 7: Differential Backup and Restore A differential database backup in SQL Server is simply a copy of every page that has had a change made to it since the last full backup was taken. We capture, in a differential backup file, the changed data pages then, during a restore process, apply that differential backup to the last full backup, also known as the base backup, in order to roll the database forward to the state in which it existed at the point the differential backup was taken. In my experience, opinion is somewhat split within the DBA community as to the value of differential database backups. Some DBAs seem to regard this third type of backup as an unnecessary complication and prefer, where possible, to restrict their backup strategy to two types of backup: full and log. Others, however, find them to be a necessity, and a useful way of reducing the time required to take backups, space required to store local backup files, and the number of log files that may need to be applied during a point-intime restore. My opinion is that differential backups, used correctly and in the right situations, are a key recovery option in your environment. The basic structure of this chapter will be familiar, so we'll be moving at a quicker pace; after discussing why and when differential backups can form a useful part of your backup and restore strategy, and some pros and cons in their use, we'll walk through examples of taking and then restoring native differential backups, using the SSMS GUI and T-SQL, gathering metrics as we go. Finally, we'll take a look a few common errors that can arise when taking and restoring differential backups. 205
