About Cloud Attached Storage
Cloud Attached Storage®combines a Network Attached Storage appliance in your local
network with online cloud services. File sharing is performed on the local network, while
cloud storage services are used for off-site backup, file sync and share (FSS), and disaster
recovery. Automated block-level incremental backup and restore functions include
de-duplication, compression, and encryption technologies, for secure and efficient
synchronization between the cloud storage service and the CTERA appliance.
About Your CTERA Cloud Attached Storage Appliance
CTERA appliances are ideal for small businesses, branch offices, and workgroups that want to
share files, synchronize folders across their network, and enjoy secure, transparent, and
disaster-proof backup of critical data.
The CTERA appliances covered in this guide include the CTERA C200, C400, and C800.
Combining the functionalities of a standalone Network Attached Storage (NAS) device, file
server, and backup tape drive in a single appliance, the CTERA appliance allows you to do all
of following:
Share files across your network
Synchronize folders across your network and the cloud
Back up files online, securely and automatically
Restore multiple file versions
Access backed-up files from anywhere, using a Web browser

Introduction

1Introduction
2 CTERA C-Series User Guide
Using the appliance, data is synchronized between your computer and the appliance drives,
then transparently backed up to an offsite storage facility in the cloud. Backups are encrypted
using high-grade AES encryption and encoded to maximize bandwidth utilization. Users can
recover files stored locally on the appliance, and even in the event that the appliance is
damaged, the files can easily be restored from cloud backup using a Web browser.
Once installed, the CTERA appliance can easily be controlled using an intuitive Web-based
interface or managed centrally through the CTERA Portal.
