ExaGrid Expands Zone-Level Deduplication Capabilities with Universal Backup Share
WESTBOROUGH, Mass. --(Business Wire)--
ExaGrid Systems, Inc. (www.exagrid.com)
the leader in scalable and cost-effective disk-based backup solutions
deduplication, today introduced Universal Backup Share, a product
feature that further expands the advantages of its zone-level
deduplication over traditional block-level deduplication approaches by
providing the ability to accept backup data from a potentially unlimited
range of backup applications, utilities and data sources. With Universal
Backup Share, only ExaGrid combines generic backup application support
with a GRID-based, scalable architecture that enables customers to keep
adding nodes as their data grows, avoiding costly forklift upgrades.
Drawing on this new capability, ExaGrid also announced support for three
additional backup applications, which can now perform backups on
ExaGrid's backup appliances: Acronis® Backup & Recovery, BridgeHead
Healthcare Data Management, and CommVault (News - Alert)® Simpana® Archive. ExaGrid is
certifying additional backup applications using the new product.
Additional announcements will be made in the coming months.
Traditional backup approaches, such as EMC Data Domain (News - Alert), use block-level
algorithms. Because block-level deduplication stores and matches unique
blocks, managing all backup data requires a hash table so large that
this approach suffers from scaling limitations. This forces an appliance
architecture consisting of a controller unit with multiple disk shelves,
with costly adverse consequences for scalability asdata grows. Because
additional processing resources are not added to handle the increased
workload with data growth, the customer's backup windows increase as
data grows and the components that determine performance remain static,
ultimately requiring a costly "forklift upgrade."
In contrast, ExaGrid uses zone-level deduplication, where backup jobs
are broken into large, variable length zones (instead of blocks). These
zones are then examined by the deduplication algorithm, which looks for
just the unique bytes from one zone to another. Unlike block-level
deduplication, the tracking tables required for zone-level deduplication
are smaller and can be easily copied across appliances allowing for a
scalable grid-based architecture. This distributed grid architecture
scales by adding full servers--disk, CPU, memory and bandwidth-with each
appliance. By adding full servers with data growth, backup windows stay
permanently short and there are no disruptive forklift upgrades.
Furthermore, only systems using zone-level deduplication can both be
part of a scalable grid architecture and be generic in nature,
supporting a very wide variety of applications. Block-level systems face
a tradeoff between scalability and broad application support.
Availability: Universal Backup Share is now available to new and
existing customers using ExaGrid's disk backup with deduplication system.
Marc Crespi, Vice President of Product Management for ExaGrid
Systems: "ExaGrid already offers the most scalable architecture in
the industry, and with Universal Backup Share, there are practically
no limitations on the number of backup applications ExaGrid now
supports, or will support soon. Only ExaGrid now provides the
advantages of both generic backup application support and scalability."
About ExaGrid's Technology:
The ExaGrid system is a plug-and-play disk backup appliance that works
with existing backup applications and enables faster and more reliable
backups and restores. Customers report that backup time is reduced by 30
to 90 percent over traditional tape backup. ExaGrid's patented
byte-level data deduplication technology and most recent backup
compression reduces the amount of disk space needed by a range of 10:1
to as high as 50:1 or more, resulting in a cost comparable to
traditional tape-based backup.
About ExaGrid Systems, Inc.:
ExaGrid offers the only disk-based backup appliance with data
deduplication purpose-built for backup that leverages a unique
architecture optimized for performance, scalability and price. The
combination of post-process deduplication, most recent backup cache, and
GRID scalability enables IT departments to achieve the shortest backup
window and the fastest, most reliable restores, tape copy, and disaster
recovery without backup window expansion or forklift upgrades as data
grows. With offices and distribution worldwide, ExaGrid has more than
5,000 systems installed at more than 1,500 customers, and more than 300
published customer success stories.
