1 ATTO FastStream NDMP 4600 features

)
The ATTO FastStream
TM
NDMP 4600 offers performance, security and reliability using NDMP
(Network Data Management Protocol) for backup of network attached storage (NAS).
NDMP is an open protocol for managing data stored on network-attached storage devices such as tape and disks, controlling data backup and recovery between primary and secondary storage.
The ideal backup solution for an NAS filer is to attach a tape library directly to the network through the ATTO FastStream NDMP 4600 to take advantage of the improved management control and operating efficiency of shared backup. The FastStream NDMP 4600 controls the backup process, enabling filers to perform at maximum capacity.
The ATTO FastStream NDMP 4600, using the NDMP Version 4 Protocol Specification, allows you to back up critical data locally using any combination of network-attached servers, backup devices and management applications from a central control, without taxing network traffic, by separating the data path and the control path.

How NDMP works

The NDMP protocol allows data backup and restoration over Ethernet networks using file-level commands, rather than block-level IO instructions.
The typical NDMP setup includes
• a Data Server (usually disks)
• a Tape Server
• a client in control of the backup process called a Data Management Application (DMA).
The DMA controls the NDMP session. There is a master-slave relationship between the DMA and the data/tape servers. The FastStream NDMP 4600 implements the Tape Service, along with a SCSI Service, to provide access to media changer devices.
A typical NDMP application involves a drive array, a Host Computer and a tape library. The Host Computer may be attached to the disk and tape drives by any of several methods/technologies. The FastStream
Control
NDMP 4600 uses Ethernet and Internet protocols. The following example is a typical NDMP DMA, Data
Server and Tape Server interaction.
1 The DMA sends messages to the tape library’s
SCSI Server to pick the appropriate cartridge and load it in the tape drive.
2 The DMA sends commands to the tape drive to
position the tape and configure the tape for writing (block size, etc.).
3 The DMA opens a connection to the Data
Server to exchange backup information.
4 The DMA commands the Tape Server to
prepare to receive data.
5 The Tape Server responds with addressing
information.
6 The DMA passes the address to the Data
server.
7 The Data Server and Tape Server send data
directly to each other.
8 Metadata generated by the DMA is written to
tape to indicate the end of files, directories, path names, etc., passed through to the tape server between backup data transfers.
• NDMP uses a windowing mechanism in which the Tape Server writes a portion of the data, then pauses and waits for the DMA to take charge. The DMA may start a new window or write some Metadata.
Control + Metadata

• The DMA may also move the tape while the transfer is paused. Once the DMA has finished with the Metadata, a new window is established and the transfer from the Data Server to the Tape Server continues.
• The Data Server has no notification of the Tape Server being paused, so it must rely on the TCP stack to queue up data transferred during the pause time, and to implement flow control when queues are full.

Installation

2.1 Setting up NDMP

NDMP (Network Data Management Protocol) provides backup for network-attached storage (NAS) devices.
NAS devices are dedicated file servers and cannot host applications such as backup software. NDMP defines a common agent to interface between any NAS device and any backup software program, minimizing demand on network resources, and enabling local backups and disaster recovery.
The ATTO FastStream NDMP 4600, using the NDMP Version 4 Protocol Specification, allows you to back up critical data locally using any combination of network-attached servers, backup devices and management applications from a central control, without taxing network traffic, by separating the data path and the control path.
Authentication by the server may require a client name-password pair, along with configuration of the security level (MD5, Text, or None) used for authentication. The FastStream NDMP 4600 does not validate the client-name, and a single password is used for all password fields within the FastStream NDMP 4600.
The NDMP port number is user-configurable, with the industry standard (10000) as the default.
NDMP device mapping links a SCSI btl (bus, target, LUN) to an ASCII device name.
Set NDMP version number and NDMP port numbers for each data port you wish to use and the NDMP authorization type for all ports. The default NDMP port number is 10000.
