User Case: How Can I Backup QNAP to Synology NAS?

☞ "Hey guys, what do you think the best way would be to backup a QNAP NAS to a Synology NAS? Is there a Synology app I can install before removing Internet access that would accomplish this, or how about a set of shell scripts that run that perform this?"

Why Need to Backup QNAP to Synology NAS?

Despite the robust features of NAS devices, relying solely on a single NAS unit for storing critical data poses risks. Hardware failures, accidental deletions, or cyber-attacks can lead to data loss, potentially causing severe disruptions to business operations or personal data loss.

  • Redundancy and Data Security: By backing up your NAS to another NAS device, such as QNAP backup to another NAS, you create data redundancy, ensuring that even if one NAS fails, your data remains intact on the backup device. This redundancy significantly reduces the risk of data loss and enhances data security.
  • Increased Storage Capacity: As data continues to grow, the storage capacity of your primary NAS may become insufficient. By backing up to another NAS with ample storage space, you can accommodate the expanding data needs.
