Create a protection group

Updated: November 1, 2013

Applies To: System Center 2012 R2 Data Protection Manager, System Center 2012 SP1 - Data Protection Manager, System Center Data Protection Manager 2010

A protection group is a collection of data sources that share the same protection configuration. Data sources within a protection group are referred to as protection group members.

When you create and configure a protection group, you specify the following:

  • Data sources—The servers, computers, and workloads you want to protect

  • Back-up storage—How the protected data should be backed up in the short-term and long-term.

  • Recovery points—The recovery points from which replicated data can be recovered.

  • Allocated disk space—The disk space that will be allocated to data in the protection group from the storage pool.

  • Initial replication—How the initial replication of data should be handled, using either over the network or manually offline.

  • Consistency checks—How replicated data should be checked for consistency

Before you can create your first protection group, ensure you’ve added a disk to the storage pool and installed agents on the computers and servers you want to add to the protection group. If you want to back up data in the protection group to tape for long-term storage, you’ll need a tape drive or library attached to the DPM server.

Create and configure a protection group

  1. In DPM Administrator Console, click Protection on the navigation bar.

  2. In the Actions pane, click Create protection group. Review the Welcome page, and then click Next.

  3. On the Select Protection Group Type page, select the data source you want to protect. For a list of workloads that DPM can protect, see Support Matrix for DPM Protection. Note that for workloads such as Exchange you’ll need to fill in a couple of additional pages in the wizard.

  4. On the Select Group Members page, select all the servers and computers you want to protect.

  5. On the Select Data Protection Method page, speciy how to want to back up protected data for long and short-term storage. For short-term storage you’ll usually back up to disk. You can also configure short-term backup to tape. If you select disk you can additionally back up the data to Microsoft Azure for short-term storage. For more information about backup options, see Plan for data storage.

  6. On the Specify Short-Term Goals  page specify how long you want to retain data in the short-term storage you selected. In Synchronization frequency, specify how often incremental backups of the data should run. Alternatively, instead of selecting an interval for incremental backups you can enable Just before a recovery point . With this setting enabled DPM will run an express full back just before each scheduled recovery point. Click Modify to change the recovery point schedule.

  7. If you added long-term tape-based storage, on the Specify Long-Term Protection Policy  page configure the retention range, backup frequency, and backup schedule for long-term storage. You can also specify a name for the tape label. If you added long-term, tape-based protection,

    With long-term storage configured the Select Tape and Library Details  page also appears. Specify the tape and library that’ll be used for back up of this protection group. You can also specify whether to compress or encrypt the backup data..

  8. On the Review Disk Allocation page recommended disk allocations are displayed. Recommendations are based on the retention range, the type of workload and the size of the protected data.

    • Data size—Size of data in protection group.

    • Disk space—The amount of disk space DPM recommends for allocation to the protection group. If you want to modify this setting you should allocate total space that’s slightly larger than the amount you estimate that each data source will grow.

    • Colocate data—If you enable colocation multiple data sources in the protection group can map to a single replica and recovery point volume. Colocation isn’t supported for all workloads.

    • Automatically grow—If you enable this setting, if data in the protected group outgrows the initial allocations, DPM will try to automatically increase the disk size by 25%

    • Storage pool details—Shows the current status of the storage pool, including total and remaining disk size.

  9. On the Choose Replica Creation Method page, specify how the initial replication of data in the protection group will be performed. If you select to replicate over the network we recommended you choose an off-peak time. For large amounts of data or less than optimal network conditions, consider replicating the data offline using removable media.

  10. On the Consistency Check Options page, select how you want to automate consistency checks. You can enable a check to run only when replica data becomes inconsistent, or according to a schedule. If you don’t want to configure automatic consistency checking, you can run a manual check at any time by right-clicking the protection group in the Protection area of the DPM console, and selecting Perform Consistency Check.

  11. On the Summary page verify the settings and click Create Group.

    DPM performs the initial replication. The protection group status is displayed on the Status page. If initial replication completes successfully an OK status will be shown.
