Frequently asked questions How is Synology’s backup solution different from other online backup services such as OneDrive or Dropbox?

Synology provides a fundamentally different approach: instead of renting storage space from a third party, you own and control your backup infrastructure.

Key differences:
  • Ownership vs. Rental: One-time purchase vs. perpetual monthly fees
  • Data Control: Your files never leave your possession unless you specifically choose cloud backup
  • Performance: Local backups at network speeds (up to 250MB/s) vs. internet-dependent speeds
  • Privacy: Complete control over who can access your data and how it's used
  • Customization: Full control over backup schedules, retention policies, and storage allocation

Unlike OneDrive or Dropbox, which primarily sync files between devices, Synology provides comprehensive backup solutions including:

  • Complete system image backups
  • Application-aware backups (databases, email servers)
  • Versioned file history with flexible retention
  • Local snapshots for instant recovery
  • Hybrid backup combining local speed with offsite security
  • This means faster recovery times, lower long-term costs, and complete independence from third-party service changes or outages.
How often should I test my backups, and what's the easiest way to do it?

Synology systems deliver superior effectiveness through advanced technology and local control:

Performance advantages
  • Speed: Local backups complete 10-50x faster than internet-based services
  • Reliability: No dependence on internet connectivity for backup operations
  • Concurrent Operations: Handle multiple backup tasks simultaneously without bandwidth limitations

Advanced features

  • Snapshot Technology: Instant point-in-time copies that online services can't match
  • Deduplication: Reduces backup storage requirements by up to 80%
  • Application Integration: Direct backup of VMs, databases, and business applications
  • Flexible Scheduling: Backup different data types at optimal times
  • Granular Recovery: Restore individual files, folders, or entire systems as needed

Cost effectivenessWhile online services seem cheaper initially, Synology systems typically pay for themselves within 2-3 years and continue saving money indefinitely. Plus, you get additional capabilities like:

  • Media streaming and organization
  • File sharing and collaboration
  • Virtual machine hosting
  • Surveillance system integration
  • Development and testing environments
  • This multi-functionality makes Synology systems far more cost-effective than paying for multiple specialized services.
What makes Synology ideal for encrypted cloud backup of private data?

Synology provides the best of both worlds: the convenience of cloud backup with uncompromising security and privacy control.

Multi-Layer Encryption Protection
  • Client-Side Encryption: Data is encrypted on your NAS before leaving your network
  • Zero-Knowledge Architecture: Even Synology cannot decrypt your data
  • AES-256 Encryption: Military-grade encryption standards
  • Encrypted Transmission: All data transfers use TLS encryption
  • Key Management: You control all encryption keys

Privacy AdvantagesUnlike consumer cloud services that may scan your content or use it for AI training, Synology's approach ensures:

  • No Content Scanning: Your files are encrypted before upload, making content analysis impossible
  • Metadata Protection: Even file names and folder structures are encrypted
  • Compliance Ready: Meets GDPR, HIPAA, and other privacy regulations
  • Audit Trails: Complete logs of who accessed what data and when

Flexible Cloud OptionsSynology gives you choice in cloud providers:

  • Synology C2 Storage: Purpose-built for Synology with optimized integration
  • Amazon S3: Enterprise-grade cloud storage with multiple tiers
  • Microsoft Azure: Integration with business Microsoft services
  • Google Cloud: Cost-effective storage with global availability
  • Backblaze B2: Budget-friendly option with excellent performance

This flexibility allows you to choose the cloud backup provider that best fits your security, performance, and budget requirements.

How do I Back up all my family's devices?

Synology NAS provides multiple recovery options for these scenarios:

For Accidental Deletion
  • Snapshots: Point-in-time copies of your data taken every few hours, stored on the NAS itself
  • Version history: Previous versions of files are automatically saved, going back days or weeks
  • Recycle bin: Deleted files are moved to a recycle bin before permanent deletion
For Ransomware Protection
  • Immutable backups: Snapshots and backups that cannot be encrypted or deleted by ransomware
  • Air-gapped backups: Offline copies that ransomware cannot reach
  • Quick recovery: Restore your entire system to a point before the infection in minutes

The key is that these protections run automatically—you don't need to remember to create restore points or manage multiple backup programs.

What happens If I accidentally delete important files or get hit by ransomware?

Testing backups is crucial—many people discover their backups failed only when disaster strikes. With a Synology NAS, testing is straightforward.

Monthly Quick Test
  • Try restoring a single file from different time periods (yesterday, last week, last month)
  • Verify you can access your cloud backups through the web interface
  • Check backup status notifications in DSM to ensure all tasks are completing successfully
Quarterly Comprehensive Test
  • Restore a complete folder from backup to verify file integrity
  • Test accessing your offsite backups from a different location
  • Verify that all family devices are successfully backing up recent files

Annual Disaster Simulation

  • Practice the full disaster recovery process: how would you restore everything to a new computer?
  • Document the steps and update any passwords or access credentials
  • Consider running a family "fire drill" to ensure everyone knows how to access important files remotely
  • The Synology backup system makes testing easy with its built-in verification tools and detailed logging, so you can quickly confirm that your family's data is truly protected.
