The Symantec Backup Exec NDMP Option uses the Network Data Management Protocol (NDMP) to back up and restore Network Attached Storage (NAS) devices.
You can back up data from a NAS device to the following locations:
A storage device that is directly connected to the NDMP-enabled NAS device (direct-attached)
A storage device that is connected to another NDMP-enabled NAS device (filer-to-filer)
A backup-to-disk device on a Backup Exec media server (remote)
A tape device that is attached to a Backup Exec media server (remote)
A shared tape device or backup-to-disk folder that is connected to a SAN with Backup Exec media servers.
You cannot back up NDMP data to a simulated tape library or to a tape device that is attached to a Backup Exec Remote Media Agent for Linux Servers.
You can restore data from a storage device on a Backup Exec media server to a NAS device. However, you cannot redirect NDMP data to a computer that runs the Windows or Linux operating systems.
You can share tape devices between single or multiple Backup Exec media servers and NAS devices by using the Backup Exec SAN Shared Storage Option. In addition, you can mix NDMP data with non-NDMP data in the same backup job.
