Deduplication & CDP

 

Data deduplication – Backup Optimization 

Ironically, current industry-standard backup practices are the number-one cause of data duplication. In the interest of data protection, the traditional backup paradigm copies data to a safe secondary storage repository over and over again, creating a large repository of redundant information.

Under this scenario, every backup perpetuates the problem, and these inefficient backup processes have created a widespread epidemic of redundant data proliferation throughout organizations. Because secondary storage volumes are growing exponentially, companies need a way to dramatically reduce these data volumes. Regulatory requirements magnify the challenge, forcing businesses to change the way they look at data protection

This is why the adoption of deduplication technology has caught on and spread rapidly over the last year. By eliminating duplicate data and ensuring that data archives are as compact as possible, companies can keep more data online longer at significantly lower costs. Deduplication has become recognized as the next evolutionary step in backup systems and is now a required technology for any company wanting to optimize the performance, efficiency, and cost-effectiveness of its backup environment.

The benefits are tangible and extremely practical: eliminating duplicate data in secondary storage archives can slash media costs, streamline management tasks, and minimize the bandwidth required to replicate data. In short, deduplication improves efficiency and saves money, making data deduplication an indispensable operational requirement. Data deduplication also can minimize the bandwidth needed to transfer backup data
to offsite archives. With the hazards of physically transporting tapes being well-established – including damage, theft, and loss among others – electronic transfer is fast becoming the offsite storage modality of choice for companies concerned about minimizing risks and protecting essential resources

Continuous data protection - Next generation protection

If deduplication is the cure for data proliferation, then prevention consists of eliminating duplicate data in the first place with a comprehensive continuous data protection (CDP) process. This is an entirely new approach that changes the paradigm of conventional data protection processes based on traditional backup with significant benefits.

Traditional backup plans focus on the backup and archiving of data rather than the protection or recovery of the whole system or site. If a system disk is damaged or corrupted, administrators are faced with the time consuming task of re-installing the operating system and application and then restoring information from previously performed backups to fully recover the entire system. This can cause many hours of costly
downtime and potentially eradicate any new data or changes that happened between the last backup job and the failure time.

In contrast, a fully deployed CDP solution provides high-speed disk-based data protection with instant, granular recovery. By keeping a complete mirrored copy of data in its native format, as well as a series of point-in-time snapshots – copies of only the changes to a dataset taken at specific points in time based on a pre-set schedule – CDP offers the most rapid and granular recovery possible in all disaster scenarios, including accidental data loss, system corruption, server or storage failures, and site-level disaster.

CDP can also employ data journaling, which protects information at a per-write level of granularity, allowing recovery of up to the last bit of information written before a service outage. Periodic protection, based on snapshots, gives IT administrators numerous bootable recovery images, delivering far more recovery points than a typical nightly tape backup. In addition, if an organization requires tape backups, CDP can accelerate tape backup speeds using a zero-impact, server-less backup model.

Having one, integrated solution for backup and DR processes will impact not only overall IT management costs, but also the ongoing operating cost of backup operations, including tape production and shipment, computing cycles, and network resources. This new approach to data protection enhances IT operations, dramatically improves service level agreements (SLA), and increases business operation efficiencies. Reducing downtime and providing constant access to business data and applications has a direct impact on the top line as well as the bottom line of an organization.
