Specifying Your Long-Term Protection Goals

更新日期: 2010年4月

適用於: System Center Data Protection Manager 2010

DPM creates a protection plan using your long-term recovery goals. You define your long-term protection plan by selecting a retention range for your data and a long-term backup schedule.

If you schedule your long-term backup on the same day that you create the protection group, the tape backup will run in the next calendar cycle. For example, if you create the protection group on January 1st, 2010 and schedule a yearly tape backup on the same day, the tape backup will not run until January 1st, 2011.

To create the protection group and to run the tape backup on the same day, in the Protection task area, in the Actions pane, click Create recovery point - Tape.

If you are not using long-term protection, skip to Choosing a Replica Creation Method.

To specify your long-term protection policy

  1. On the Specify Long-Term Protection page, in the Retention range box, Type or select how long you need your backed-up data available. You can select a retention range between 1 and 99 years.

  2. In the Frequency of backup box, select the backup frequency that you want. The backup frequency is based on the specified retention range, as shown in the following list:

    • When the retention range is 1–99 years, you can select backups to occur daily, weekly, bi-weekly, monthly, quarterly, half-yearly, or yearly.

    • When the retention range is 1–11 months, you can select backups to occur daily, weekly, bi-weekly, or monthly.

    • When the retention range is 1–4 weeks, you can select backups to occur daily or weekly.

    note附註
    On a stand-alone tape drive, for a single protection group, DPM uses the same tape for daily backups until there is insufficient space on the tape. For multiple protection groups, DPM requires separate tapes. Therefore, we recommend that you minimize the number of protection groups that you create if you are using a stand-alone tape drive for your backups.

  3. Click Restore Defaults to restore the defaults back to a three month retention range and a weekly backup frequency.

  4. In the Protection Objectives section, click Customize to change the tape label and to customize the schedule of backup jobs for your recovery goals. This schedule will replace the default schedule.

  5. To change the long-term backup schedule, click Modify. You have a number of scheduling options for long-term protection, depending on your retention range and backup frequency. For more information, see the following Changing Your Long-Term Backup Schedule section. If you are not modifying the long-term backup schedule, click Next.

Changing Your Long-Term Backup Schedule

You can use the Modify Long-Term Schedule screen to change your long-term backup schedule. The following table lists the backup frequency and the schedule you can change depending on the retention range you selected. After you modify the long-term backup schedule, click OK, and then click Next.
