Chapter 3: Full Database Backups Once this has been configured, click OK to finalize the new file configuration and click OK again on the Select Backup Destination dialog box to bring you back to the Back Up Database page. Now that we are done with the General page of this wizard, let's take a look at the Options Page, shown in Figure 3-6. Figure 3-6: Configuration options for backups. 102
Chapter 3: Full Database Backups The Overwrite media section is used in cases where a single file stores multiple backups and backup sets. We can set the new backup to append to the existing backup set or to overwrite the specifically named set that already exists in the file. We can also use this section to overwrite an existing backup set and start afresh. We'll use the option of Overwrite all existing backup sets since we are only storing one backup per file. This will make sure that, if we were to run the same command again in the event of an issue, we would wind up with just one backup set in the file. The Reliability section provides various options that can be used to validate the backup, as follows: • Verify backup when finished Validates that the backup set is complete, after the backup operation has completed. It will make sure that each backup in the set is readable and ready for use. • Perform checksum before writing to media SQL Server performs a checksum operation on the backup data before writing it to the storage media. As discussed in Chapter 2, a checksum is a special function used to make sure that the data being written to the disk/tape matches what was pulled from the database or log file. This option makes sure your backup data is being written correctly, but might also slow down your backup operation. • Continue on error Instructs SQL Server to continue with all backup operations even after an error has been raised during the backup operation. The Transaction log section offers two important configuration options for transaction log backups, and will be covered in Chapter 5. The Tape Drive section of the configuration is only applicable if you are writing your backups directly to tape media. We have previously discussed why this is not the best way for backups to be taken in most circumstances, so we will not be using these options (and they aren't available here anyway, since we've already elected to back up to disk). 103
