The role of the HP D2D Backup System
The HP D2D Backup System provides disk-based data protection with data deduplication. For
additional data protection and disaster protection D2D Backup Systems can perform replication
of data over low bandwidth WAN links. This is a good solution to move data offsite without the
media handling and transport costs. D2D Backup Systems provide either virtual tape or NAS
emulation. This guide will only feature the NAS emulation and its implementation with NetBackup.
The D2D NAS targets have deduplication on by default and this cannot currently be changed. The
NAS targets can use either the CIFS (Common Interchange File Standard) or NFS (Network File
System) protocol. CIFS is used with Windows servers and NFS is used on all LINUX/Unix operating
systems. This guide will cover the CIFS protocol for Windows.
NOTE:
It is important to note that, besides the more obvious disk capacity specification, there
are some important additional NAS specifications such as maximum files per share, maximum
number of shares, and maximum number of concurrent open files. These vary depending upon the
D2D Backup System model, see Appendix A for details.
Network connection
NAS shares are all accessed from the network connections and use the CIFs or NFS protocol.
NOTE:
It is important to check that the correct network settings are used especially if the D2D
Backup System is to join a domain. Ensure that the entries for the DNS server, domain and gateway
are correct. (Normally the network admininistrator will provide these).
All D2D Backup Systems have dual 1Gb Ethernet connections;the larger D2D4312 and D2D4324
units have two additional 10Gb Ethernet connections. The network interfaces can be used on
different subnets or can be bonded together (not 1GbE to 10GbE) for high throughput or high
availability mode. It would be normal to have inter-site replication configured for a different subnet.
The initial IP address can be set using the utility disk supplied with each D2D Backup System. This

information. If the dynamic DNS option is set, the D2D Backup System will be entered automatically
