Disk based backup and simple end-user file recovery deliver a low total cost of ownership.As a member of the Windows Server System Manager family, DPM has been designed to optimize disk-based backup and recovery of Windows file servers and is the fastest and most cost effective method to recover file data lost to user error or equipment corruption. HP has worked closely with Microsoft on DPM and as such, ProLiant Data Protection Storage Servers have been optimized to deliver simplicity without compromise, resulting in a solution that is cost effective and easy to implement while providing immediate business value.Data Protection Storage Servers complement existing IT data protection infrastructures and are non-disruptive to IT environments. They can be extended further into the data protection value chain through optional SCSI interface and tape backup software to deliver a disk-to-disk-to-tape data protection framework.
