Intel drivers5/7/2023 ![]() This fallback mechanism allows administrators to hot-add/remove devices, better resist hardware failure scenarios, and provide software-based compression where needed. ![]() The interface for Intel ® QAT devices uses a software library called QATzip where the QATzip API maintains a built-in software fallback mechanism. This feature is designed to give tangible improvements both in terms of reduced CPU usage and backup completion times, as well as a reduction in storage consumption. ![]() Intel® QuickAssist (Intel QAT) technology in SQL Server 2022, solves these challenges by providing hardware acceleration and CPU offload capabilities for enhanced compression and decompression functions. ![]() Many customers in high-volume online transaction processing (OLTP) environments put their business continuity and disaster recovery (BCDR) strategy at risk by delaying their regular backup schedules in order to remain operational for customer workloads. While customers use the current compression standard, the challenge many customers have with the current compression implementation is that the compression ratios are frequently too low to justify the additional compute overhead required to compress the backup files.Īdditionally, customers cannot offload the compute overhead of the compression task. The default configuration in SQL Server is to not compress backups, but many users change this default globally using sp_configure. Compressing backup data benefits customers in two ways: first, the backup files will consume less storage, and second, since there are fewer bytes being transferred, the backups run faster than uncompressed backups. Using the metadata in the backup file header, the RESTORE command decompresses compressed backup files. SQL Server backup compression provides the compressed backup option for all streaming SQL Server backup types-full, differential, and transaction log. In SQL Server 2008 Enterprise Edition, backup compression was introduced adding WITH COMPRESSION as an option in the T-SQL backup command.
