Note
The term tape libraries refers to both multi-drive tape hardware and stand-alone tape
drives.
Consider the number of tape backup jobs and the size of the protected data when planning the
capacity of your tape library. You must also consider the hardware features: a tape library without
an autoloader requires manual tape rotations when jobs are being performed.
To plan for the number of tapes you will need for each protection group, multiply the backup
frequency by the retention range.
The tape labels for tapes used for long-term protection are assigned when you create a protection
group. DPM will assign a default tape label in this format: DPM - <ProtectionGroupName> -
long-term tape <number>. Before you begin creating protection groups, you should plan your
tape naming scheme if you do not want to use the default scheme.

End-User Recovery Considerations
Your deployment plan should specify the data for which end-user recovery will be enabled and
the DPM servers that must be configured in Active Directory Domain Services to provide end-
user recovery.
End-user recovery enables end users to independently recover data by recovering previous
versions of their files. End users can recover previous versions through shares on file servers,
through DFS Namespaces, or by using a command on the Tools menu of Microsoft Office 2003
applications.
If you currently have Shadow Copies of Shared Folders enabled on a computer that you protect
with DPM, you can disable that feature and regain the disk space that it uses. End-users and
administrators will be able to recover files from the recovery points on the DPM server.
Enabling end-user recovery requires configuring the schema of Active Directory Domain
Services, enabling the end-user recovery feature on the DPM server, and installing the recovery
point client software on the client computers.
Configuring Active Directory Domain Services
Configuring Active Directory Domain Services to support end-user recovery involves four
operations:
1. Extending the schema
