accessed (or hot) data is stored in the high-performance primary tier. In this way, the I/O
performance of the service host is enhanced.

Backup Application
The N8300 supports an integrated NetBackup Enterprise Client, or via the Network Data
Management Protocol (NDMP).
l
When using the IP-based NDMP backup option, the backup server must be connected to
the backup media, such as a tape library. You must configure the NDMP option.
l
Prior to backup, an NDMP control command is sent to the N8300 through a backup server.
Upon receiving the command, the N8300 transfers the data to be backed up to the
NetBackup Media Server over the IP network, and then the NetBackup Media Server writes
the data onto the backup media.
l
The N8300 has a built-in NetBackup client. If the NetBackup client is used for backup, the
NetBackup Master Server and Media Server are required in the application environment.
Meanwhile, if the Domain Name Server (DNS) is used, it should be able to resolve the
NetBackup server IP address. After the network is connected, configure the NetBackup
server on the N8300, and then configure the backup policy on the NetBackup Master Server.
After configuration, backup starts automatically according to the defined backup policy
without requiring any manual intervention.
