Sample text
The convention is now used for backward compatibility. Three versions later, isn’t it time for a more appropriate name for that stored procedure? 25 26 CHAPTER 2 ■ MAKING DATABASE BACKUPS Dropping a Backup Device Dropping a backup device is even simpler than creating one: Sp_dropdevice @logicalname='AWBackup' This command only removes the backup device definition—it doesn’t automatically delete the files contained therein. Use this command to remove all the files in addition to the device definition: Sp_dropdevice @logicalname='AWBackup', @devfile='DELFILE' The literal 'DELFILE' is required for completely dropping the device and all the files associated with it—not the most intuitive command.
Without a complete transaction history from a full or differential backup, point-in-time recovery cannot occur. SQL Server 2005 Books Online (BOL) has excellent recommendations for pre and post actions when switching between recovery modes. I’ll revisit changing recovery modes in Chapter 5 when I show you how to begin building a cohesive backup/restore strategy. CHAPTER 2 ■ MAKING DATABASE BACKUPS T-SQL Backup Most people consider using T-SQL commands to be the ideal way to initiate and manage database backups.
That unease helps keep you on your toes. However, it’s also the key to why a restore process can unravel. The restoration process is inherently filled with emotion and pressure from management, creating a need for teamwork and constant communication with business users. In this book, I’ll talk about all of these aspects, but first you need to understand the technical process, devoid of any external factors or pressures. In Chapter 5, I’ll discuss overall planning, and Chapter 13 will focus on the types of business and interpersonal pressures that can make this job so difficult.
