Two types of backup can be performed, either over the network or as an off-host
backup.
• In an over-the-network configuration, all backup data is transmitted over the
network to the backup server using a backup agent that is resident on the
server.
• In an off-host backup solution, some of the servers with the larger file stores
do not back up their data over the network. Instead the storage array takes a
snapshot of the LUN and then mounts this copy directly to the backup server.
This process increases overall backup speed as no backup files are
transmitted over the normal network to cause additional network contention
issues.
In many forensics labs today, backups are conducted over 10 GB networks.
