across the organization to a single Backup system. This not only simplifies backup but means that restore
is easier too.
The 1U, 2U, 4U StoreOnce Backup systems are easily rack-mounted in standard racks for efficient use of
space in the data center and remote offices. Supported by all leading backup applications, this allows each
system to be installed and used without additional investment in software.
Enhance reliability
By automating and consolidating backup you can reduce operator intervention and consequently user-
generated errors. Furthermore, HP StoreOnce Backup systems include hardware-based RAID 5 or RAID 6 to
reduce the risk of data loss due to disk failure.

deduplication
- keep more data on
disk for longer
Data deduplication is a method of reducing storage needs by eliminating redundant data so that over time
only one unique instance of the data is actually retained on disk. As a result, typically 20x more backup
data can be retained (up to 1.4 petabytes) in the same disk footprint.
Adding data deduplication to disk-based backup delivers a number of benefits:
A cost effective way of keeping your backup data on disk for a number of weeks or even months.
More efficient use of disk space effectively reduces the cost-per-gigabyte of storage and the need
to purchase more disk capacity.
Making file restores fast and easy from multiple available recovery points. By extending data
retention periods on disk, your backup data is more accessible for longer periods of time, before
archiving to tape. In this way, lost or corrupt files can be quickly and easily restored from backups
taken over a longer time span.
Ultimately, data deduplication makes the replication of backup data over lower bandwidth WAN
links viable (providing offsite protection for backup data) as only changed data is sent across the
connection to a second device (either a second identical device or one that comes from this product
family).
HP StoreOnce deduplication
HP StoreOnce deduplication software simplifies the deployment of deduplication technology across IT
infrastructures. With explosive data growth driving IT sprawl, deduplication technology is quickly
becoming a requirement for many customers to help reduce the capacity required to store information.
Traditional deduplication technologies tend to approach the problem from a fragmented
perspective and this results in multiple deduplication methodologies being deployed adding to the
management complexity of the infrastructure. HP StoreOnce is different; as a next generation
deduplication architecture, it is not sold as standalone software, but rather is a portable engine that
can be consistently embedded in multiple products, eliminating the complexity of first generation
deduplication. HP StoreOnce uses patented innovation and features designed by HP Labs to
maximize backup and restore performance while minimizing management and hardware overhead.
How it works
Deduplication works by examining the data stream as it arrives at the storage appliance, checking for
blocks of data that are identical and eliminating redundant copies. If duplicate data is found, a pointer is
established to the original set of data as opposed to actually storing the duplicate blocks, removing or
"deduplicating" the redundant blocks from the volume. The key here is that the data deduplication is being
done at the block level to remove far more redundant data than deduplication done at the file level where
only duplicate files are removed.
