Network-attached storage (NAS) devices have become essential for managing, storing, and safeguarding data. Whether you’re a business owner looking to protect critical information or an individual preserving personal memories, it’s crucial to implement robust backup strategies to reduce the risk of data loss. 

This guide will explore five Synology NAS data recovery & backup strategies, discussing their advantages, disadvantages, and practical considerations.

Backup to a Directly Attached USB Hard Disk


User-Friendly Implementation. The process is straightforward, and the NAS vendor’s web interface makes file management and copying easy.


Lack of Automation: This method does not have automation features, requiring manual initiation, verification, and physical attachment of the external disk.

Potential Inconsistencies: Simultaneous file access or modifications during the copy process may result in inconsistent backups.

This strategy suits those who prefer a hands-on approach but may not be the best choice for those seeking automation and efficiency.

RAID (Redundant Array of Independent Disks)


RAID configurations distribute or replicate data across multiple disks, ensuring continued operation even if one disk fails.


  • While it guards against drive failures, RAID is not a complete solution for accidental deletions or data corruption.
  • Setting up and managing RAID configurations can be complex, requiring technical expertise.
  • RAID is like a safety net for drive failures but doesn’t cover all bases when it comes to protecting your data from every angle.

Cloud Backup Services


  • Cloud backup services provide offsite storage, safeguarding data against physical damage, theft, or disasters. It will help during NAS data recovery when the problem occurs. 
  • Automation. These services typically offer automated backups, eliminating the need for manual intervention.


  • Subscription Costs: While convenient, utilizing cloud backup services often involves subscription costs that can accumulate over time.
  • Connectivity Dependency: Backup speed and accessibility depend on internet connectivity, subject to network limitations or outages.

Cloud backup services offer accessibility and offsite storage advantages but may come with ongoing subscription costs and reliance on internet connectivity.

Snapshot Technology


Efficient Recovery: Snapshots capture the state of files or folders at specific points, providing a quick and efficient way to recover data without excessive storage usage.


  • Depending on the NAS model, snapshot retention periods may be limited.
  • While suitable for smaller-scale recoveries, snapshots might not be ideal for large-scale backups or certain types of data.

Snapshots are like a rewind button for your data, allowing you to efficiently recover to specific points in time. However, their applicability may vary depending on your data recovery needs.

Hybrid Backup Solutions


  • Hybrid solutions combine multiple backup methods, offering redundancy and increased resilience against data loss.
  • They provide a layered approach, ensuring data is protected across various platforms and locations.


  • Implementing hybrid backup solutions might introduce complexity to the backup infrastructure.
  • Managing multiple backup systems could potentially increase operational challenges and costs.

Hybrid solutions are like an all-encompassing shield, combining different strategies for comprehensive data protection. However, they may require careful management due to their complexity.

Finding the Balance

Choosing the right NAS backup strategy is a balancing act that depends on data criticality, budget, and ease of management. While each approach has distinct advantages, a hybrid approach that combines multiple strategies generally provides the most comprehensive protection against data loss.

It’s essential to select a strategy that aligns with your specific needs. A directly attached USB hard disk might suffice if you prefer a straightforward, hands-on approach. RAID configurations are a solid choice for those seeking a safety net against NAS file recovery. Cloud backup services are ideal for those prioritizing offsite storage and automation, even with subscription costs in mind.

Snapshot technology provides an efficient recovery option for smaller-scale incidents, while hybrid backup solutions offer the most comprehensive protection for those willing to navigate a more intricate backup infrastructure.

Regardless of the chosen strategy, reliable data recovery must be considered. In the event of data loss, Recovery Squad specializes in retrieving lost data from various storage devices.
