Red Gate SQL HyperBac. Developed by Red Gate Software Ltd., is a compression and encryption tool for SQL Server backups. It can compress files up to 95% and provides users with an option to backup to other file formats like .zip. This program runs as a Windows Service and intercepts read and write requests whenever a user creates a backup or runs a restore. Because the application executes file compression and encryption externally, there is no need to modify or configure the SQL Sever. SQL Hyperbac works directly with standard T-SQL BACKUP and RESTORE, so no special syntax is needed and likewise, there is no need to alter back-up routines. It uses its own dictionary-based lossless compression algorithm and utilizes the compression storage formats SHRINK, SHRINKFAST (proprietary format), and DEFFLATE. HyperBac uses a 256-bit AES encryption to secure files and to prevent unauthorized access to confidential data.
