Building reliable backup repositories with Synology storage systems

Safe and intelligent storage systems are key to keeping a business running. This is no different for backup systems used to protect IT infrastructure. Synology storage solutions include our Active Backup suite, a powerful family of applications introduced in 2018 to safeguard endpoints, servers, VMs, and even Microsoft 365 and Google Workspace accounts.

At the same time, many businesses run third-party backup software to store backups on their Synology system. In fact, Synology’s range of converged NAS/SAN storage systems has been deployed at tens of thousands of companies worldwide, including nearly half of Fortune 500 companies, to store business-critical data and backups. While the data stored is (hopefully) seldom used, you still need a robust and dependable solution.

Pairing backup solutions with Synology storage

Our customers often deploy Synology systems as reliable storage destinations for backups with products by Nakivo, Acronis, Commvault, and Veeam, among others. Nakivo even offers direct integration with Synology DiskSkation Manager (DSM) through an add-on package available in Synology’s Package Center.

The easiest way to connect storage solutions with any backup software is through file protocols such as SMB or NFS. These enable easy storage and folder management. The second method is to set up designated LUNs, or block storage, essentially providing blank virtual drives to be formatted and managed directly by backup software servers.

Synology systems fully support configuration as backup repository servers managed through DSM, using SMB or NFS protocols, and managed through backup software servers, using LUNs over iSCSI or Fibre Channel1 protocols.

Dependable backup storage when it counts

Synology NAS/SAN storage systems are powered by DSM, our operating system that makes configuration and operation highly straightforward. A reduced learning curve ensures that IT administrators spend less time digging through documentation or requesting technical support. When every second counts during a backup recovery event, a system with minimal friction can make the difference.

DSM is far more than just a simplified user interface, it packs in quality of life improvements for day-to-day operations, such as centralized performance, security, and backup monitoring across all of your Synology systems through our Active Insight service. Smart storage management features make sure your storage use is efficient through compression and deduplication, and hardware maintenance tasks are easy for any on-site staff to perform.


Most importantly, Synology systems are designed to keep your data intact and secure from external and internal threats. From data snapshots and remote backups to private cloud or hybrid cloud architectures, Synology systems offer a complete selection of flexible solutions to ensure data and service reliability. Learn more about data protection
