DPM configures the protection policy, or schedule of jobs, for each protection group based on the recovery goals that you specify for that protection group. Examples of recovery goals are as follows:
- “Lose no more than 1 hour of production
- “Provide me with a retention range of 30
- “Make data available for recovery for 7
Your recovery goals quantify your organization's data protection requirements. In DPM, the recovery goals are defined by retention range, data loss tolerance, recovery point schedule, and, for database applications, the express full backup schedule.
The retention range is how long you need the backed-up data available. For example, do you need data from today to be available a week from now? Two weeks from now? A year from now?
Data loss tolerance is the maximum amount of data loss, measured in time, that is acceptable to business requirements, and it will determine how often DPM should synchronize with the protected server by collecting data changes from the protected server. You can change the synchronization frequency to any interval between 15 minutes and 24 hours. You can also select to synchronize just before a recovery point is created, rather than on a specified time schedule.
The recovery point schedule establishes how many recovery points of this protection group should be created. For file protection, you select the days and times for which you want recovery points created. For data protection of applications that support incremental backups, the synchronization frequency determines the recovery point schedule. For data protection of applications that do not support incremental backups, the express full backup schedule determines the recovery point schedule.
