How Data Scrubbing Keeps Data Safe: Using Epis Technology to Make Storage More Reliable

One of the most quiet but dangerous threats to digital information is data corruption. Over time, files can slowly get worse, sometimes without any warning, which can permanently damage important data like documents, system files, or photos that can’t be replaced. Epis Technology uses Synology’s advanced data scrubbing technologies to help businesses get rid of these risks and make sure that their data stays safe and their business keeps running.

We explain how RAID scrubbing and Btrfs data scrubbing work below, as well as how Epis Technology combines these features into safe, enterprise-level storage plans.

Understanding the Basics: RAID and Redundancy

Before you learn about data scrubbing, you need to know how RAID keeps your data safe. RAID (Redundant Array of Independent Disks) puts together several drives into one storage pool to make sure that data is safe and can be recovered in case of a failure. One of the most common types of RAID is RAID 5. It uses parity blocks to rebuild data if a drive fails.

This redundancy is very important, but it only works perfectly if the parity information stays correct over time. That’s when RAID scrubbing becomes very important.

What RAID Scrubbing Does

RAID scrubbing goes through each parity stripe in the array to make sure the data is correct according to the RAID 5 parity formula. The system keeps recalculating things until everything is in the right place if it finds any problems. This makes sure that data recovery gives accurate results if a drive fails.

But RAID scrubbing by itself can’t tell which data block might be broken. It only makes sure that things are the same, not that they are right. This means that RAID scrubbing can accidentally copy a corrupted block across the array if there is corrupted data.

Modern Synology systems use the Btrfs file system to fix this bigger problem. This is where Epis Technology comes in to help you protect your data.

Btrfs Data Scrubbing: A Way to Keep Data Safe from Hidden Corruption

Checksums are used in file system data scrubbing to add a higher level of protection. A Btrfs volume has a unique data checksum and a unique metadata checksum for each file written to it. The system does the following during scrubbing:

  • Recalculates the checksum
  • It checks it against the stored checksum.
  • Checks metadata checksums against each other
  • Uses RAID redundancy to fix broken blocks

This stops silent data corruption (bit rot) by making sure that the contents of each file can be checked and restored.

Epis Technology sets up Synology deployments to get the most out of these protections. They make sure that checksum verification is properly turned on, optimized, and watched based on the client’s workload.

Finding a balance between performance and safety

Btrfs checksum verification works very well, but it can slow down workloads like:

  • Database
  • Virtual machines
  • Surveillance videos

Epis Technology looks at each client’s environment to figure out where checksum-based scrubbing should be turned on. This makes sure that performance is at its best without hurting integrity.

Synology’s Unified Data Scrubbing makes sure that all of your data is safe

Data Scrubbing is an automated process that combines RAID scrubbing and Btrfs scrubbing into one. It makes sure that

  • Btrfs scrubbing for accuracy
  • Consistency (through RAID scrubbing)

Epis Technology sets up automated scrubbing schedules and keeps an eye on your system all the time, making sure that it finds and fixes problems before they become major failures.

How Epis Technology Helps Businesses Keep Their Data Safe

Epis Technology’s main focus is on designing and managing enterprise backup and storage solutions that use Synology systems as their main components. We offer the following services:

  • Planning storage architecture with the best RAID setups
  • Deployments with Btrfs for integrity checks based on checksums
  • Automated scrubbing schedules and monitoring of the whole system
  • Finding and fixing early data corruption before it happens
  • Ongoing help with NAS health, redundancy, and long-term dependability

Your data is still safe, recoverable, and consistent, which gives your business peace of mind and operational confidence.

Epis Technology makes sure that your digital assets stay accurate, safe, and strong for years to come by using expert Synology installation, ongoing maintenance, and in-depth knowledge of infrastructure.
