You can use special characters such as # ? @ \ $ () {} [] in your protection group
name. However, you cannot use the following five special characters: & < > ‘ “
2. In the Protection policy section, select your protection method:
• I want short-term protection using. Select this check box for short-term protection
and then select the media you want to use from the drop-down list.
Note
If you do not have a tape library attached to the DPM server, only Disk is
available for short-term protection.
• I want long-term protection using tape. Select this check box for long-term
protection.
If you are using tape for both short-term and long-term protection, DPM creates copies of
the latest short-term tape full backup to generate your long-term tape backup. Therefore,
we recommend that you schedule your short-term protection full backup to run a day prior
to your long-term protection. This scheduling enables your long-term tape backup to
leverage the short-term tape backup that DPM created the day before. If you schedule
the long-term tape backup to run prior to the short-term tape backup, the long-term
backup will not take advantage of the latest short-term full backup.

Specifying Your Short-term Protection Goals
DPM generates a protection plan using your short-term recovery goals. You define your short-
term recovery goals by selecting a retention range for your data, specifying how frequently you
want the data synchronized, and scheduling the creation of your selected recovery points.
A recovery point is a snapshot or point-in-time copy of the data sources that are protected by your
DPM server.
Retention range is the duration of time for which the data should be available for recovery. DPM
retains recovery points for the duration specified in the retention range. Any day that the replica is
not consistent does not count toward the retention range. When DPM protection is stopped
temporarily because the replica is inconsistent, DPM does not delete expired recovery points until
protection resumes.
To specify short-term protection goals
1. On the Specify Short-Term Protection Policy page, in the Retention range box, select
the duration of time that you want the data to be available for recovery.
You can select a retention range between 1 and 64 days for short-term disk-based
protection.
