USE [master] GO Chapter 7: Differential Backup and Restore BACKUP DATABASE [DatabaseForDiffBackups] TO DISK = N'C:\SQLBackups\Chapter7\DatabaseForDiffBackups_Diff_Native_2.bak' WITH DIFFERENTIAL, NAME = N'DatabaseForDiffBackups-Differential Database Backup', STATS = 10 GO Listing 7-5: Native T-SQL differential backup for DatabaseForDiffBackups. Having run the command, you should see results similar to those shown in Figure 7-5. Figure 7-5: Native differential T-SQL backup script message output. Figure 7-6 summarizes the storage requirements and execution time metrics for our second differential backup, compared to the first differential backup. 222
Chapter 7: Differential Backup and Restore Differential Backup Name Number of Rows DatabaseForDiffBackups_Diff_ Native_1.bak DatabaseForDiffBackups_Diff_ Native_2.bak Figure 7-6: Differential backup statistics, Part 2. 223 Execution Time (S) 10000 0.31 3.2 110000 1.57 20.6 Storage Required (MB) So, compared to the first differential backup, the second one contains 11 times more rows, took about five times longer to execute, and takes up over six times more space. This all seems to make sense; don't forget that backup times and sizes don't grow linearly based on the number of records, since every backup includes in it, besides data, headers, backup information, database information, and other structures. Compressed differential backups By way of comparison, I reran the second differential backup timings, but this time using backup compression. Just as for full backups, the only change we need to make to our backup script is to add the COMPRESSION keyword, which will ensure the backup is compressed regardless of the server's default setting. Remember, this example will only work if you are using SQL Server 2008 R2 or above, or the Enterprise edition of SQL Server 2008. Note that, if you want to follow along, you'll need to restore full and first differential backups over the top of the existing DatabaseForDiffBackups database, and then rerun the third data load (alternatively, you could start again from scratch).
