As backups grow over time, getting a successful backup of key data, systems, and virtual machines can be challenging. As that data grows, the need for deduplication becomes more and more apparent to reduce the duration of time involved to successfully secure the backup while reducing the space consumed by these backups. This can be rather challenging dilemma for datacenters that are doing more with less.

Symantec has answered the call with their <strong><a href="http://eval.symantec.com/mktginfo/enterprise/fact_sheets/b-datasheet_be_2010_deduplication_option.pdf">Symantec Backup Exec 2010 Deduplication Option</a></strong>.

Backup Exec’s Deduplication Option offers 3 methods for deduplicating data across the enterprise:

<!--more-->

<strong>* Client Deduplication - "</strong>Deduplication at the Source" - Client deduplication removes redundant data at the source, leading to to lower memory and bandwidth utilization. This method frees up more client resources for production services in both physical and virtual environments. Deduplicating information closer to the source will also decrease the network traffic associated with the backup and reduce the storage footprint as well.

* <strong>Media Server Deduplication - </strong>Deduplication that takes place on the Media Server at the time of the backup. This method enables deduplication that is integrated diretly into media server. Simply create a Deduplication Storage Folder, and the Backup Exec media server now offers inline deduplication by processing data streams in flight; requires no extra staging disks for processing, leading to more optimal use of storage.

* <strong>Appliance Deduplication - </strong>Leverage investments in Deduplication Appliances thru Symantec's OST (OpenStorage) Partner Program. This will improving backup times and management of deduplication and replication functions built into intelligent Deduplication Appliances.

The Deduplication Option enables customers to use any of these methods to achieve deduplication for file servers, application servers, and virtual machines. This is also great for remote offices that point back to the central backup exec server, especially as you consider reducing the amount of backup data travelling from remote offices back to the backup server by 90%.

Below are a couple key stats that should not be overlooked:

1. Significantly reduces the amount of backup data stored by 9:1 (90%) or more for File System backups

2. Significantly reduces the amount of backup data stored by 6:1 (80%) or more for Application backups

3. Client Deduplication provides significant bandwidth savings over traditional backups, making remote office backup practical

4. Media Server Deduplication provides significant storage savings for VMWare ESX and vSphere 4.0 backups

5. Integration with Deduplication Appliances through Symantec’s Open Storage protocol allows Backup Exec to manage appliance deduplication and replication functions

6. Improve backup performance while using Appliance Deduplication when compared to CIFS or NFS transfers

7. Reduce the amount of backup data travelling from remote offices back to the backup server by 90%
