Specify Short-Term Goals
Applies To: System Center Data Protection Manager 2007
Use the SpecifyShort-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 (https://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 is based on the synchronization frequency when incremental backup is supported. 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 (https://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. |
