DPM cannot manage the space in custom volumes. If DPM alerts you that a
custom replica volume or recovery point volume is running out of space, you
must manually change the size of the custom volume by using Disk
Management.

Specifying Your Long-term Protection Goals
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, 2007 and schedule a yearly tape backup on the same day, the tape backup will not
run until January 1st, 2008.
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
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
