2. In the Synchronization frequency section, do one of the following:
• Select Every, and then select the frequency at which you want to synchronize the
replica on your DPM server with the changes on your protected server. For
application data protection, the synchronization frequency also determines the
recovery point schedule. You can select a synchronization frequency interval of
anywhere from 15 minutes to 24 hours.
The default behavior is every 15 minutes, which means that the DPM server will
never be more than 15 minutes behind the computer it is protecting. The average
Recovery Point Objective (RPO) is 15 minutes from any event that critically impacts
the computer or disk.
• Select Just before a recovery point to synchronize the data just before a scheduled
recovery point.
When you select this option, recovery points for all protection group members are
created according to the schedule you configure. The network traffic is potentially
greater at the time of synchronization when you select this option.
For more information about synchronization, in the "DPM 2007 Operations Guide",

(http://go.microsoft.com/fwlink/?LinkId=91859).
3. To specify the recovery points:
• Recovery points for files. Click Modify to change the recovery point schedule for
file data. Recovery points for files are created according to the schedule you
configure.
• Application recovery points. Click to create recovery points for application data
after each synchronization. For data protection of applications that do not support
incremental backups, such as SQL Server databases using the simple recovery
model, the express full backup schedule determines the recovery point schedule
• Express full backup. Click Modify to change the express full backup schedule. To
enable faster recovery time, DPM regularly performs an express full backup, which is
a type of synchronization that updates the replica to include the changed blocks.
Note
Performing frequent express full backups may impact performance on the
protected server. For more information about express full backups, in the
DPM 2007 Operations Guide, s
(http://go.microsoft.com/fwlink/?LinkId=91859).
DPM can store a maximum of 64 recovery points for each file member of a protection
group. For application data sources, DPM can store up to 448 express full backups
and up to 96 incremental backups for each express full backup. To support end-user
recovery, the recovery points for files are limited to 64 by Volume Shadow Copy
Service (VSS).
4. On the Modify Recovery Points screen, specify the times of the day and the days of the
week that you want to create a recovery point, and then click OK.
