SQL Server Backup and Restore - Simple Talk

Chapter 8: Database Backup and Restore with SQL Backup Pro
Backing up DatabaseForSQLBackups (full database) to:
C:\SQLBackups\Chapter8\DatabaseForSQLBackups_Full_2.sqb
Database size : 1.074 GB
Compressed data size: 6.679 MB
Compression rate : 99.39%
Processed 125208 pages for database 'DatabaseForSQLBackups', file 'DatabaseForSQLBackups' on file 1.
Processed 1 pages for database 'DatabaseForSQLBackups', file 'DatabaseForSQLBackups_log' on file 1.
BACKUP DATABASE successfully processed 125209 pages in 5.974 seconds (163.742 MB/sec).
SQL Backup process ended.
Figure 8-8: SQL Backup T-SQL script results.
We are now presented with two result sets. The first result set, shown in Figure
8-8, provides our detailed backup metrics, including database size, and the size and
compression rate of the resulting backup file. The second result set (not shown) gives us
the exit code from SQL Backup, an error code from SQL Server and a list of files used in
the command.
We can see from the first result set that the new backup file size is just under 7 MB, and
if we take a look in our directory we can confirm this. Compared to our first Red Gate
backup, we can see that this is a bit less than double the original file size, but we will take
a closer look at the numbers in just a second.
After these metrics, we see the number of pages processed. Referring back to Chapter 3
confirms that this is the same number of pages as for the equivalent native backup, which
is as expected. We also see that the backup took just 6 seconds to complete which, again,
is roughly double the figure for the first full backup. Figure 8-9 compares these metrics to
those obtained for native backups, and compressed native backups.
