Use the Specify Short-Term Goals page of the Create New Protection Group Wizard to generate your short-term disk-based recovery goals.

This page contains the elements described in the following table.

Elements

Name Description

Retention range

Type or select how long you need your backed-up data available.

You can select a retention range between 1 and 64 days for short-term disk-based protection.

Synchronization frequency: Every

Click this option to select how often you want to synchronize the replica on your DPM server with the changes on your protected computer. 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.

Synchronization frequency: Just before a recovery point

Click this option 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.

Note
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, see Managing Performance (http://go.microsoft.com/fwlink/?LinkId=91859).

Recovery points for files: Modify

Click Modify to change the recovery point schedule for file data. Recovery points for files are created according to the schedule you configure.

For file protection, you select the days and times that you want DPM to create your recovery points to accommodate your business needs and recovery requirements.

Application recovery points

Recovery points for application data are created after each synchronization.

For data protection of applications that do not support incremental backups, for example SQL Server databases using the simple recovery model, the express full backup schedule determines the recovery point schedule

Express full backup: Modify

Click Modify to change the express full backup schedule. To enable faster recovery time, DPM regularly performs an express full backup, a type of synchronization that updates the replica to include the changed blocks.

Note
Performing frequent express full backups may impact performance on the production server. For more information about express full backups, in the DPM 2007 Operations Guide, see "Express full backups" in Managing Performance (http://go.microsoft.com/fwlink/?LinkId=91859).

For application data protection, the recovery point schedule is based on the synchronization frequency for incremental backups. If incremental backups are not supported, the recovery points are based on the express full backup schedule.

After specifying your short-term recovery goals for the protection group, click Next.
