Data Deduplication Software for Enterprises

What is Deduplication Software?

With a large number of users, hardware, and software distributed across a network, most enterprises will find that several dozen copies of the same file or data set exist on the network and take up unnecessary storage space. Deduplication software works to find these duplicate file or data instances and eliminate the excess so that there is one master copy. In other instances where the data previously existed, the process of data deduplication creates pointers that direct users toward the remaining copy that matches what they’re looking for.

Depending on the tools you use and the results you’re hoping to achieve, different types of deduplication will help you to eliminate redundant data across your network:

File-Level Deduplication

The simplest type of deduplication, this approach eliminates duplicate file copies, leading to single instance storage (SIS).

Block-Level Deduplication

This approach gets more granular than file-level deduplication, finding and reducing matching blocks of data, regardless of the different files where they’re found. Block-level deduplication tends to free up more space than file-level deduplication.

Fixed Deduplication

This type of block-level deduplication breaks data into blocks of all the same size, with little to no regard for the actual contents of each block. Fixed deduplication saves unique blocks and eliminates duplicate blocks simultaneously.

Variable Deduplication

The variable approach to block-level deduplication uses context when breaking data into blocks. This means that the blocks can all come in different lengths, but are divided based on their unique properties.

Source Deduplication

One of two locations where deduplication software can be deployed, source deduplication is where data is deduplicated in primary storage before it travels to the backup system. This approach takes less time and uses less bandwidth, but it requires more processor resources and is typically more difficult to implement than target deduplication.

Target Deduplication

The more common of the two deployment location approaches, target deduplication deduplicates data after it has reached the backup system. It’s usually easier to deploy than source deduplication and comes in two different subcategories: inline deduplication and post-process deduplication.

Inline Deduplication

Inline is the type of target deduplication in which dedupe happens before the backup copy is written on disk or tape. It requires less overall storage space than post-process, but it often takes longer to complete the backup process.

Post-Process Deduplication

Post-process is the type of target deduplication that takes place after the backup has been written to disk or tape. This process is often faster than inline deduplication, but it requires additional storage space to complete.

Local Deduplication

Local deduplication is when deduplication happens in only one node, without consideration for duplicate data in other network nodes.

Global Deduplication

Global deduplication is when deduplication efforts are applied across all nodes on a network, ensuring the most accurate, comprehensive deduplication results.

Important Deduplication Software Features

Before your organization selects a deduplication product for your network optimization goals, ask yourselves the following questions:

  • Cross-platform integrations: Does this solution integrate with other relevant data platforms? Can you connect your CRM and/or ERP platforms to optimize those data sets?
  • Data matching algorithms: What kinds of data matching does this tool offer? Can it handle both structured and unstructured data? Does it use machine learning or other algorithms to find data matches?
  • Data masking and security features: Does this platform offer data masking or other security solutions that protect personal and otherwise sensitive data from unauthorized users?
  • Data and file recoverability: Will this tool allow you to recover data and files that are accidentally eliminated? Is there a record of dedupe actions available to admin users of the tool?
  • Fuzzy matching: Does the tool offer fuzzy matching, or the intuitive ability to identify texts and other data that are nearly identical?

Who Needs Deduplication Software?

Enterprises of virtually any size and specialty can benefit from deduplication software, but these tools are particularly advantageous for organizations that find themselves in these scenarios:

Dealing with Large Amounts of Distributed Data

For companies that store important customer and strategic data across several different locations in their network, deduplication helps to save space and prevent redundancy across platforms. Deduplication can be particularly useful for organizing personnel files in CRM, ERP, and HR platforms.

Acquiring New Data Assets

When companies are going through the mergers and acquisitions (M&A) process, they don’t typically know the exact contents of the assets they’ll gain from the deal. After the fact of acquisition, deduplication can help organizations to clean up new data, optimize storage space, and quickly merge that data into existing company assets.

Looking for Cost and Space Savings

The primary reason that most companies opt into deduplication software solutions is that they are looking for a way to save money and avoid upgrading their network storage.

Handling Data Backup and Recovery

If your company does a lot of data backup and recovery work, deduplication software can simplify your work to make sure that data is only backed up one time.
