Service Pack 1 for Microsoft System Center Data Protection Manager (DPM) 2007 provides continuous data protection for Windows application and file servers using seamlessly integrated disk and tape media and includes the following expanded capabilities:
In addition to enhancing the protection of each of the core Microsoft application workloads, additional capabilities have also been introduced with the release of DPM 2007 SP1, such as:
All of this new functionality builds on the features released in the DPM 2007 ‘Rollup Update’ in June 2008, which provided protection of Windows Server 2008, including Windows Server 2008, Windows Server 2008 core, Windows Server 2008 System State and BitLocker™ support – as well as new tape media capabilities around tape sharing and media library sharing.
Between ‘Rollup Update’ and Service Pack 1, most of the core features of DPM 2007 have seen incremental capabilities or workload advancements which promises to keep Data Protection Manager on a trajectory toward improving how Microsoft customers protect and recover their Windows application and file servers with the Microsoft backup and recovery solution.
