  • Examining today's data protection solutions

    Exponential data growth, the need for more frequent data protection, the rise of server virtualization and a variety of other challenges have emerged over the past few years, and backup vendors have begun to offer alternatives to traditional nightly ... 

  • Identify and conquer today's backup challenges

    The last several years have brought about changes and challenges for backup administrators. Many have relied upon the same approach to data backups for decades, but the tried-and-true approach of nightly backups is becoming impractical. Exponential d... 

  • The backup target today

    There are many backup target options available with a wide range of price points. They include everything from tape drives and tape libraries to virtual tape libraries, deduplication arrays, integrated backup appliances and cloud backups.

  • What is data protection?

    Data backups have evolved to the point that they are hardly recognizable. For many organizations, the days of producing a nightly backup to tape are over. Exponential data growth and the need for near real-time data protection have driven organizatio... 

  • The benefits of data archive storage

    Data archiving is firmly entrenched as a storage management best practice. SearchStorage surveys indicate that 70% of companies use some form of archiving for email, file systems, databases or other applications. Archiving yields multiple benefits, s... 

  • How dedupe fits into your data backup plan

    The fourth chapter of this e-book discusses things to consider about the way deduplication is performed and the ways that dedupe integrates with other data protection processes. It offers information about how deduplication can impact restore time an... 

  • The debate over global deduplication

    Combining both source and target deduplication might sound promising, but there’s one major disadvantage: Source + target dedupe solutions tend not to scale very well. The sheer volume of data that needs to be backed up often causes the backup target... 

  • Choose the right dedupe approach

    Data deduplication technologies have existed in various forms for years, but now, dedupe is a standard in our current IT landscape. Expert Brien M. Posey explains how you can master the concept and ensure your backups are the best fit for your compan... 

  • What is deduplication?

    Data deduplication has evolved from the most cutting-edge emerging technology to an everyday backup capability. Access this e-book to get backup expert Brien Posey's insight into hardware and software deduplication, cloud backups and the combination ... 

  • What you should know about the deduplication process

    Deduplication technology is mature and there are a variety of options available depending on your organization's specific needs. This e-book compares hardware- and software-based deduplication, source and target deduplication, global deduplication an... 

  • delta differencing

    Delta differencing is an incremental approach to backup that only backs up blocks that have changed after the first full backup. The differences are recorded in files called deltas. 

  • centralized backup

    Centralized backup is a process that involves automatically replicating data from remote sites and sending it over a network to a main (centralized) location for storage. 

  • data archiving

    Data archiving is the process of moving data that is no longer actively used to a separate data storage device for long-term retention. 

  • data reduction

    Data reduction is the process of minimizing the amount of data that needs to be stored in a data storage environment. Data reduction can increase storage efficiency and reduce costs. 

  • source deduplication

    Source deduplication is the removal of redundancies from data before transmission to the backup target. 

  • target deduplication

    Target deduplication is the removal of redundancies from a backup transmission as it passes through an appliance sitting between the source and the backup target. 

  • inline deduplication

    Inline deduplication is the removal of redundancies from data before or as it is being written to a backup device. 

  • post-processing deduplication (PPD)

    Post-processing deduplication (PPD), also known as asynchronous de-duplication, is the analysis and removal of redundant data after a backup is complete and data has been written to storage. 

  • global data deduplication

    Global data deduplication is a method of preventing redundant data when backing up data to multiple deduplication devices. 

  • data deduplication (Intelligent compression or single-instance storage)

    Data deduplication (often called "intelligent compression" or "single-instance storage") is a method of reducing storage needs by eliminating redundant data... (Continued)
