ExaGrid announced that a newly published ESG technical review, ExaGrid with Commvault: Maximum Deduplication Savings with Easy Management authored by
Kerry Dolan, Sr. IT Validation Analyst and Craig Ledo, IT Validation
Analyst, documents ESG's validation of ExaGrid testing that demonstrated
both the capacity savings and ease of use available from a combined
ExaGrid and Commvault backup solution. The data deduplication from
Commvault can remain turned on and ExaGrid furthers the Commvault
deduplication by a factor of 3:1.
From the ESG report:
"It
is well known that both ExaGrid and Commvault offer backup solutions
that are easy to use and can help you to store data more efficiently
with deduplication. What may be less well known is that a combined
ExaGrid and Commvault solution can achieve even greater deduplication:
up to 20:1 in many cases. A 20x reduction in backup storage costs can be
a significant boost to any budget.
ESG validated that:
- The
combined ExaGrid/Commvault solution reduced a 123TB backup data set
that included 15 days of file data, VMware VMs, and SQL database backups
down to 8.66TB, a 14:1 reduction, in a realistic yet intentionally
conservative test environment.
- Deploying and managing the combined solution was simple, intuitive, and fast."
ExaGrid
Tiered Backup Storage requires close integration between the backup
software and the backup storage. Together, Commvault and ExaGrid provide
a cost-effective backup solution that scales to meet the needs of
demanding enterprise environments. ExaGrid improves the storage
economics of Commvault environments by working with Commvault
deduplication on to provide up to 20:1 reduction in storage consumption -
a 3X storage savings over using Commvault deduplication alone. This
combination dramatically lowers the cost of onsite and offsite backup
storage.
Commvault
deduplicated data can be sent to ExaGrid appliances for further
deduplication. ExaGrid takes the average 5:1 Commvault deduplication
ratio up to 15:1 which reduces the storage footprint by 300%. This
greatly reduces the cost of the backup storage while allowing no change
to the current Commvault configuration since the Commvault deduplication
can remain on. In this example, ExaGrid can replicate the 15:1
deduplicated data to a second site for offsite long-term retention and
disaster recovery. The additional deduplication saves WAN bandwidth in
addition to saving storage at both sites.
"ExaGrid
continues to innovate to optimize integration with the backup
applications we support, providing our customers with unique benefits
for the backup applications that they use. We have been able to further
deduplicate Commvault's deduped data for some time now to maximize
storage savings, and this new report highlights how well this actually
works, all without requiring current Commvault users to make changes to
their configuration," said Bill Andrews, President and CEO of ExaGrid.
"We hope that current Commvault users and those who are planning to use
Commvault will take a look at this report and consider the storage
savings that ExaGrid can bring to their backup environment. Separately,
ExaGrid can greatly improve Commvault backup and restore performance if
Commvault deduplication is turned off. In this case, ExaGrid provides
the same storage savings but with greatly improved backup and restore
performance. ExaGrid gives Commvault customers the option to keep
Commvault deduplication turned on, or for improved performance, turned
off."
