• Verify that you do not have more than 100 protectable data sources on a single volume. If

you do, distribute your data sources across more volumes if possible.

• All protection group members of the same type (file or application data) will have the same

recovery goals. However, within the same protection group, files can have different recovery

goals than application data.

Exception: If a SQL Server database is configured to use the Simple Recovery Model or is

the primary database in a log shipping pair, the recovery goals for that database will be

configured separately from the recovery goals for all other application data.

• All storage groups on a computer running Exchange Server 2003 must be members of the

same protection group.

• When you select a data source that contains a reparse point (mount points and junction

points are data sources that contain reparse points), DPM prompts you to specify whether

you want to include the target of the reparse point in the protection group. The reparse point

itself is not replicated; you must manually re-create the reparse point when you recover the

data.

Special Considerations for Protecting Data on
Workstations

Your recovery goals for data on user workstations might differ from the recovery goals for data on

file servers. You should consider placing file servers and workstations in different protection

groups so that you can adjust the synchronization schedules separately. For example, if you

synchronize data on file servers every 15 minutes, any workstations that belong to the same

protection group as the file servers are also synchronized every 15 minutes.

Special Considerations for Protecting Data Over a
WAN

Network bandwidth usage throttling and on-the-wire compression are performance optimization

features that are particularly important for deployments in which a DPM server protects data over

a wide area network (WAN) or other slow network.

On-the-wire compression is configured at the protection-group level.

Network bandwidth usage throttling is configured at the protected-computer level. In addition, you

can specify different network bandwidth usage throttling rates for work hours, non-work hours,

and weekends, and you define the times for each of those categories.

When protecting application data such as Exchange storage groups or SQL Server databases

over a WAN, consider reducing the schedule for express full backups.
