7 likes1,299 views
The document summarizes Microsoft's Data Protection Manager (DPM) 2007 software. It describes how DPM 2007 provides continuous data protection for Windows servers like Exchange, SQL and SharePoint by taking periodic snapshots of blocks that have changed and transmitting them to the DPM server. It also discusses how DPM 2007 supports protection of clustered servers and databases through integration with features like cluster shared volumes and database mirroring.

- 4. Customer Backup Pains Better nightly backups needed Tape is inefficient Lack of application support WAN not feasible for centralized backups Disk-based backup consumes large amounts of space Remote and branch-office data protection is expensive and cumbersome Customers want one vendor to manage everything

DPM Recovery Points Point-in-time snapshot of protected data source Discrete recovery point Stored in a VSS replica on DPM server Created by express full backup process Created at regular intervals or custom schedule Comparable to a conventional full backup Uses the Exchange Backup APIs to ensure log file truncation is properly handled
- 9. How DPM 2007 Protects Data
- 10. DPM Finds Files that Make Up Data D:\ + \SQL_data + \Customer.MDF E:\ + \SQL_logs + \Customer.LDF
- 11. DPM Identifies Blocks that Compose Files DPM filter creates a volume map, to monitor which disk blocks contain portions of the files to be protected. DPM Filter – Volume Map D:\ + \SQL_data + \Customer.MDF E:\ + \SQL_logs + \Customer.LDF

- 54. Top Reasons To Plan for DPM 2007 No more failed recoveries Near zero data loss for Exchange, SQL, and SharePoint Seamless Disk-to-Disk-to-Tape for backups Recoveries within minutes instead of hours Unified policy allows protection of multiple data types to any media – in one schedule and with common tuning options Eliminate the backup window of your production servers Shrink potential data loss down to 15 minutes Application recovery direct from backup UI – no pre-staging Enable end-users to perform their own recoveries Remove tapes from branch offices and centralize backups at the datacenter
