How Epis Technology Helps Businesses Get the Most Out of Their Storage by Debunking Data Deduplication Myths

Synology

As businesses today create huge amounts of files, backups, and application data, their storage systems need to grow without becoming too big to handle or too expensive. Data deduplication is one of the best ways to do this. It is a technology that finds and gets rid of duplicate data before it is stored.

Every vendor says they can save you a lot of money or give you “20x higher deduplication ratios,” but these marketing claims often don’t take into account the things that affect deduplication performance in the real world. Businesses need to know how deduplication works, how ratios are figured out, and how an expert partner like Epis Technology makes sure that planning is accurate, deployment is done right, and long-term efficiency is maintained.

How Data Deduplication Works

Data deduplication cuts down on storage space by looking at data blocks, giving each one a unique ID, and comparing new blocks to what is already stored. The system doesn’t save a duplicate block again; instead, it makes a small index pointer that points to the original block.

This process cuts down on a lot:

Use of storage
Times for backups
Using bandwidth
Total cost of infrastructure

As ransomware attacks and the need for more data grow, deduplication becomes necessary to keep data protection systems affordable, scalable, and safe.

Epis Technology helps businesses set up Synology-powered deduplication solutions that get the best reduction rates while keeping backups safe and secure.

How to Really Figure Out Deduplication Ratios

When comparing solutions, it can be hard to tell which ones are better because vendors often use different methods to figure out deduplication ratios. Synology and Epis Technology both suggest checking deduplication at the time of data transmission (Stage 2) to get a true picture of performance.

The Three Stages That Vendors Talk About:

Step 1: Original Data Set

The size of all the data before it was deduplicated. This number is often used in marketing because it makes ratios look bigger.

Stage 2: Size of the Data Transfer (Most Accurate)

How much data is actually sent to the destination after duplicate data is removed.

Stage 3: The Data That Is Actually Stored

How much data is finally stored on the backup server?

A lot of vendors talk up Stage 1 results and say things like “95%+ data reduction.” In real businesses, true deduplication efficiency is usually between 40% and 66%, depending on how often and what kind of backups are made.

Epis Technology helps clients understand these numbers correctly so they don’t overestimate how much storage they can save or underestimate how much infrastructure they will need in the future.

Synology Deduplication in Action: How It Affects the Real World

Taiwan Shiseido is one example. They used Synology’s inline and block-level global deduplication to increase their usable storage space by 52%.

Synology’s deduplication is more affordable than that of many proprietary backup appliances. When set up correctly, it is one of the best TCO-optimized solutions.

Epis Technology makes sure that these features are set up to fit the needs of each organization:

How often to back up
Types of data
Policies for keeping things
Requirements for compliance
Goals for the budget and growth

Why Inline and Global Deduplication Are Important

1. Inline Deduplication

Before writing data to storage, Synology removes duplicates.
This:

Takes away the cost of temporary storage
Instantly lowers the amount of storage space needed
Makes backups go faster

2. Global Deduplication at the Block Level

Not only is redundant data removed from one machine, but it is also removed from all backup sources.

This is great for businesses that need to back up:

Many PCs
Virtual machines
Servers for files
Directories for shared storage

Epis Technology ensures deduplication is optimized across all backup jobs, improving efficiency without compromising performance.

The Hidden Truth: Deduplication Alone Isn’t Enough

While deduplication reduces TCO and maximizes storage, it must be part of a larger, enterprise-grade data-protection strategy.

Epis Technology integrates Synology’s deduplication with:

Immutable storage
Multi-version backups
Air-gapped cloud backups
Hybrid disaster recovery planning
Business continuity architectures

This ensures that—beyond saving space—your business remains operational even in the face of ransomware, hardware failure, or human error.

Why Businesses Choose Epis Technology for Synology Deduplication

Data is an organization’s most valuable asset, and protecting it requires more than simply buying storage—it requires expert planning, proper configuration, and ongoing optimization.

Epis Technology ensures businesses deploy Synology’s deduplication technologies effectively, maximizing storage capacity, reducing long-term costs, and improving backup reliability across the entire IT ecosystem.
