Plan recovery goals

Updated: November 1, 2013

Applies To: System Center 2012 - Data Protection Manager, System Center 2012 R2 Data Protection Manager, System Center 2012 SP1 - Data Protection Manager

You define recovery goals for data in each protection group. Recovery goal settings include a retention range, synchronization frequency, and a recovery point schedule.

You should set realistic recovery goals for each data source that you will protect. Not all information or data maintained on your company's computers requires equal protection, nor does all of it merit the same investment in protection. Your deployment plan should establish recovery goals for each data source according to your business needs for protection of that data.

In DPM, you set your recovery goals in terms of synchronization frequency, recovery point schedule, and retention range, as follows:

  • Synchronization frequency should be selected based on your data loss tolerance, or how much data you can lose. You can specify the synchronization for a protection group to occur as frequently as every 15 minutes. You can also specify less frequent synchronizations. At a minimum, DPM must synchronize the replicas for a protection group at least once between recovery points.

  • The recovery point schedule establishes how many recovery points of this data should be created and when. A recovery point is the date and time of a version of a data source that is available for recovery from media that is managed by DPM.

  • The retention range is how long you need the backed-up data available. To determine your retention range needs, consider the pattern of recovery requests you experience in your enterprise. If requests are concentrated within two weeks of data loss, 10 days might be an appropriate retention range for you. If requests are concentrated at a later time, you might need a longer retention range.

For example, your recovery goals for a specific Exchange Server database could be that the most recent data is never more than 30 minutes old, that you can select from versions created at 30-minute intervals, that it will be available for recovery from disk for 14 days, and that it will be available for recovery from tape for 3 years.

For more information, see Recovery Goals for Disk-Based Protection, and Recovery Goals for Tape-Based Protection.

Recovery goal options for storage methods

The following table lists the recovery goal options for each DPM protection method.

Recovery Goal Options for Protection Methods

 

Protection method Retention range Synchronization frequency or backup schedule Recovery points

Short-term on disk

1–448 days

For file members in a protection group, DPM can store a maximum of 64 recovery points (this is a VSS limit for client accessible shadow copies). If you schedule one recovery point per day (7 per week), you can retain 64 recovery points for a maximum of 448 days (7 * 64 = 448 days).

For applications, there is a maximum of 512 available recovery points. However, DPM reserves 64 recovery points, so you can only select up to 448 recovery points for applications. This is because DPM assumes that file protection could use the same volume as the applications you are protection, so the VSS shadow copies apply to the same volume. Therefore, 448 + 64 = 512 (which is the VSS shadow copy maximum per volume).

Select a frequency between 15 minutes and 24 hours, or select Just before a recovery point.

When a specific synchronization frequency is selected:

  • Recovery points for files are created according to the schedule you configure.

  • Recovery points for application data are created after each synchronization.

When Just before a recovery point is selected, recovery points for all protection group members are created according to the schedule you configure.

Short-term on tape

1–12 weeks

Select to back up:

  • Every day

  • Every week

  • Every two weeks

Instead of recovery points, you configure one of the following backup types:

  • Full and incremental backups

  • Only full backup

When you select weekly or every two weeks, only full backup is available. You specify the day and time.

When you select daily full backups, you specify the time.

When you select daily full and incremental, you specify the day and time for the full backup and for the incremental backup.

Long-term on tape

Minimum: 1 week

Maximum: 99 years

Select to back up:

  • Daily

  • Weekly

  • Biweekly

  • Monthly

  • Quarterly

  • Half-yearly

  • Yearly
