Data deduplication is the process of examining data to identify any redundancy. The same data keeps getting backed up over and over again, consuming more storage space and impacting cost—thereby creating a chain of inefficiency. Rather than duplicate a copy of the same file, a pointer can be used to go to a previously stored version, reducing the physical capacity needed for a backup job.

Our featured guest speakers for this chat include Greg White, Dell / EMC storage marketing manager for Global Commercial Marketing, Sanjeet Singh, and Paul Davis from Dell’s Product Group, as well as Darin Camp from CommVault.

Technical Community - Background Reading

You may be considering adding deduplication into your environment, or you may have just heard all the buzz about it and want to know more about the specifics of deduplication. This chat discusses deduplication in a backup setting and how it helps make the cost of backup to disk approach the cost of backup to tape. Join us for a chat with experts that can help you understand:

• The capacity savings versus processing resources and time required for file, block, and sub-block–level deduplication methods
• The potential benefits of deduplication, such as:

• Shortening the backup window
• Reducing storage capacity, power, cooling and space requirements
• Eliminating redundant data transfers that are needlessly consuming network resources
• Centralizing data protection and archive, reducing the burden on staff, and eliminating tape requirements at remote offices
• Enabling cost-effective disaster recovery (DR)
• How deduplication may move from backup to disk to archive and other areas with static or inactive content as the technology evolves
• The pros and cons of source-based deduplication, such as reducing network congestion, common management benefits, ease of use, and reduced costs versus the limited availability of it
• The pros and cons of target-based deduplication, such as ease of integration into complex environments and ease of implementation versus the cost and management considerations and no network congestion reduction
• The time and resources trade-offs of in-line versus post-processing deduplication
• Other considerations, such as if your data would be a good candidate for deduplication, deduplication ratios, deduplicating across multiple sites, protecting remote offices, and more
