In DPM you got a great feature that gives you the possibility to restore data without interrupt your LAN traffic and get great speed in the restoring process. How is this possible? The answer is using SAN based recovery using hardware snapshots.
There are three things you must be aware of.
First: The DPM server and the protected server must be both connected to the same SAN, Or the zoning in the SAN must be configured so the LUN presented to the protected computer and the DPM server is the same.
Second: A SAN where hardware snapshot functionality is enabled
Third: Your SAN must be able to create clones and split a clone to make it writable
