Overview
The ETERNUS CS800 is Fujitsu's midrange Enterprise disk backup solution that integrates
data deduplication and replication technology to connect backup and disaster recovery
protection across distributed corporate environments. This disk-based backup appliance
uses data deduplication technology to decrease the typical disk capacity requirements very
efficiently, and make WAN replication a practical, cost-effective part of disaster recovery
planning. The ETERNUS CS800 is designed for departmental and medium business
customers.

Disk-Based Backup Appliance

The ETERNUS CS800 system uses high speed disk RAIDs for backup data storage. In
comparison to a tape-based backup solution, the ETERNUS CS800 significantly reduces
the time required for backup/restore jobs and improves the reliability that backup jobs
complete within their planned backup window.
