Overview
The ETERNUS CS800 is Fujitsu's entry level and midrange disk backup solution that
integrates data deduplication and replication technology to connect backup and DR (disaster
recovery) protection across distributed corporate environments. The ETERNUS CS800 disk-
based backup appliance uses Fujitsu's patented data deduplication technology to increase
disk capacities by 10 to 50 times, and make WAN replication a practical, cost-effective part
of disaster recovery planning. The ETERNUS CS800 is designed for departmental and
medium business customers.
2.1.1
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.
2.1.2
Advanced Data Deduplication Increasing Disk Retention for Backup
Data
The ETERNUS CS800 leverages Fujitsu's patented data deduplication technology (U.S.
Pat. No. 5,990,810) to dramatically increase the role that disk can play in the protection of
critical data. With the ETERNUS CS800 solution, users can retain 10 to 50 times more
backup data on fast recovery disk than with conventional arrays.
2.1.3
Remote Replication of Backup Data Providing Automated Disaster
Recovery Protection
With the ETERNUS CS800, users can transmit backup data from a remote site to a central,
secure location to reduce or eliminate media handling. ETERNUS CS800 replication is
asynchronous, automated, and operates as a background process.
2.1.4
Configurable Storage Presentation
Storage can be presented in the following three ways:
NAS shares.
l
OST Logical Storage Units (LSUs)
