Barracuda Networks 4 用户手册

42      Barracuda Backup Service Administrator’s Guide

Barracuda Networks leases space in a number of Tier 3 & 4 facilities across the world. Each of these 
storage locations is equipped with:

• Controlled access systems requiring key-card authentication and physical check-in.
• Video-monitored access points.
• Intrusion  alarms.
• Locking cabinets.
• Climate control systems.
• Waterless fire suppressant systems.
• Redundant power (generator backup, UPS, no single point of failure).
• Redundant Internet connectivity.

The Barracuda Cloud Storage infrastructure boasts high-quality RAID redundant hardware with hot-
spare drives in every file server and near instant data mirroring over high-speed fiber connections 
between the storage locations.

In the United States, data is transmitted from Barracuda Backup Servers to one datacenter and then 
replicated to another. The process of replicating data begins immediately after it is copied from a 
Barracuda Backup Server and runs continuously. Data in the Barracuda Cloud Storage is stored in 
parts and no single computer in the storage system has all the parts required to reconstruct data. Each 
of these computer systems communicates in unison to deliver restored data securely. This diverse 
storage system serves to further strengthen the physical security of your data.

With this architecture, Barracuda Networks equipment can maintain up to three distinct copies of your 
data which can be stored in three geographically disparate locations.

Access to Barracuda Backup Servers is limited to approved Barracuda Networks employees on an ‘as 
needed’ basis. Employee activity is logged and all logs are archived to an independent storage device.
