A protection agent is software that you install on each of the computers that you want to protect with DPM. The protection agent performs the following functions:
- Records changes to protected data in a change journal. The
protection agent creates a separate change journal for each
protected volume and stores the journal in a hidden file on that
- Transfers the change journal from the protected computer to the
DPM server to enable DPM to synchronize the replica.
- Allows the DPM server to browse the shares, volumes, and
folders on the protected computer.
A protection agent is controlled exclusively by the DPM server from which it is installed. You cannot assign an installed protection agent to work with a different DPM server.
The protection agent software consists of two components: the protection agent itself and an agent coordinator. The agent coordinator is software that is temporarily installed on a protected computer during installation, update, or uninstallation of a protection agent.
