These release notes provide information about the LiteSpeed Engine for SQL Server release.
LiteSpeed Engine for SQL Server is a complementary technology to LiteSpeed for SQL Server product. LiteSpeed Engine for SQL Server allows seamless data compression and encryption without having to modify existing SQL scripts.
By providing LiteSpeed’s compression and encryption functionality in a driver based solution, users can continue using native or third party backup tools, while getting the full advantage and flexibility of LiteSpeed’s time and space saving features.
The LiteSpeed Engine solution consists of two parts, which are both installed by default:
File driver component—This does the actual work of compressing and optionally encrypting your SQL Server database backups. It works by intercepting the backup file stream and compressing the results before reaching the actual physical disk. If restoring a database, the operation is reversed – the file stream is decompressed before reaching SQL Server.
Once installed and configured, the driver will work transparently in the background, compressing and decompressing and optionally encrypting and de-encrypting your SQL Server backups and restores.
