DMT SQL Backup Manager

From DMT Software:

DMT SQL Backup Manager is a powerful tool for creating, compressing and protecting your SQL Server backups. Compatible with SQL Server 2000 and 2005, it includes a range of features to make backups faster, simpler and more secure. The backup files generated by this application are up to 90% smaller than the original SQL Server backups. The compression you can achieve depends upon the type of data stored in the database; if the database contains a lot of highly compressible data, such as text and uncompressed images, you can achieve higher compression.

SQL Backup also enables you to encrypt your backup files to prevent unauthorized access. This is especially important because compressed backups are much smaller and, therefore, you are much more likely to transfer them over the network. You can use SQL Backup to create full database backups, differential database backups, transaction log backups, and file or file group backups.
