Disk-based Backup Solution with Data Protection Manager
As the latest member of the Windows Server System family, Data Protection Manager (DPM) is a server software application that optimizes disk-based backup and recovery. Backing up data to disk provides the fastest way to recover data lost because of user error or software and hardware corruption. With DPM, recovering information is as simple as browsing a share and copying directly from to the production server.
DPM lets IT administrators easily and affordably use existing Windows Server investments such as Active Directory, Microsoft Windows Server 2003, and Microsoft Windows Storage Server 2003. DPM provides these unique capabilities:
• Rapid and reliable data recovery. DPM provides rapid and reliable recovery of data lost because of user error or server hardware failure.
• Efficient and near-continuous data protection. DPM uses efficient byte-level replication to deliver faster backup and less potential data loss.
• Operational Simplicity. DPM lowers the total cost of your data protection environment by improving the efficiency of your operations.
• Backup and restore wizards. Set file server protection policies with a couple of clicks.
• Comprehensive recovery and verification. Administrators can now have complete control and real-time information on the status of their data backups.
• Designed to work with current tape archive software. DPM integrates with established tape-based backup and recovery software to enable long-term archiving of data.
Rapid and reliable recovery
Predictable data recovery from disk
Because DPM is disk-based, it can take advantage of the additional reliability benefits of a redundant array of inexpensive disks (RAID) for protection. This is an advantage over tape because tape has the potential to be a single point of failure.
Validation and fix-up process
This is a process conducted by DPM to ensure that the replication job worked correctly. The process has two components:
• Replication validation. DPM automatically validates the replica against the production server to ensure that the replication is consistent and has occurred as planned.
• Replication fix-up. If, during validation, inconsistencies between a data source and its replica are found, the fix-up activity resends the object(s) from the data source to the replica.
The most common scenario for recovering lost or corrupted files is a request by the end user to the IT help desk to find an archived version. Assuming that the business has an archiving system in place, this request usually means a costly and time-intensive search of archived media that, in many instances, is a tape backup. DPM provides practical recovery alternatives:
• Delegation of recovery activities. IT administrators can delegate simplified administration and recovery to less-specialized file server administrators, help desk personnel, or even end users. If the end user is unable to locate a file or folder, administrators can still provide assistance because they have the full recovery user interface available.
• File and full server recovery. DPM is designed not only to recover files and folders, but also to recover shares if they are deemed inconsistent or corrupt, or full server recovery if there has been a hardware failure with replica disks or the server running DPM.
In addition to being integrated across all Windows Server System products, DPM is also integrated with the most commonly used business productivity tools: the Microsoft Windows XP operating system and Microsoft Office 2003.
Efficient and near-continuous protection
Efficient data protection
Because DPM logs and replicates only byte-level changes to files on production servers, it affects production server performance much less than a full tape backup would.
Flexible replication scheduling
IT administrators set the replication frequency using declarative data-management specifications tailored to match the business value of the data. IT administrators can also customize protection schedules for specific data sources, and they can review and update their protection plans as data replication and volumes change.
The most common data replication modes are hourly and daily. DPM also provides the flexibility to specify a customized replication schedule that meets the recovery time objective (RTO) and recovery point objective (RPO) goals of the business. Volume Shadow Copy Service (VSS) is used as a second-tier option to enable the rapid recovery of files from a past point in time.
• Daily. Analogous to an incremental backup, this mode occurs only once a day. Backup mode replication matches replication and shadow copy jobs to ensure data integrity between copy versions.
• Hourly. This mode causes replication to run on an hourly basis.
Frequent shadow copies
Shadow copies are block-level copies of any changes that have occurred to protected objects on a production server since the last shadow copy. Only the changes are copied, not the entire file.
Scheduling of shadow copies
Shadow copies can be scheduled independently of the replication schedule. DPM builds on the VSS infrastructure to create nearly instantaneous shadow copies that can be stored on the server running DPM. This allows you to browse through and recover deleted or corrupted files from multiple points in time. These objects are cached on the server running DPM before being copied to the tape backup during the regularly scheduled backup process.
Protection from network outages and hardware failures
The DPM Agent logs and replicates the data from each of the production servers to the server running DPM. If the production server goes down or is destroyed, a copy of the data is still available on the server running DPM. If the network goes down, the agent that is local on the production server continues to cache all the changes in the production server until the network is working again.
You can minimize the impact that data protection replication has on your network because DPM has the capability to throttle network traffic. You can set minimum network performance metrics to control scheduled data replication processes so that, if the network is busy, the replication process will not negatively affect network performance.
IT administrators can, at any time, perform a backup to tape of data from the server running DPM, and do so without compromising product server performance. This feature increases the overall efficiency of the data-protection infrastructure and lowers total protection costs. This enables businesses to change their scheduled nightly tape backups to daytime, further reducing the need to have specialized administrators available on nights and weekends.
Lower cost of acquisition
Because DPM uses industry-standard hardware and software, its acquisition cost is much lower than that of any other proprietary, expensive data protection technology.
Lower training costs
Because DPM is part of Windows Server System, it contains tools that are already in your server software, such as Microsoft Management Console (MMC) and Windows Explorer, and that are familiar to IT administrators.
Automation of discovery and common tasks
When initially installed, DPM automatically discovers all the production servers in the domain that need to be protected. As new servers are added to the network, DPM discovers and alerts the administrator that unprotected servers exist in the environment, creating a seamless protection, recovery, and maintenance solution.
Simplified administration allows the delegation of recovery and simplified administrative tasks, report creation, and process automation. Some examples include:
• Automated protection schedule
• Rich reporting and monitoring
• Integration into the Windows Server environment
• Cost-effective recovery
Fewer tape backups
With DPM, IT administrators can maintain 30 days' worth of shadow copies on disk and create tape backups for disaster recovery scenarios on a less-frequent basis. This policy results in fewer tape backups and less money spent on tape media.
For IT professionals responsible for backing up Windows file servers, DPM provides rapid and reliable recovery, efficient and near-continuous data protection, and operational simplicity by making the most of the benefits of disk based backup instead of existing tape backup technologies.
