Part 2: Why Backup Synology NAS to OneDrive or OneDrive to Synology NAS?

If you are wondering why Synology OneDrive backup connection on either side is useful, first, you should understand the common strategy in place. The importance of Synology NAS is notable in periods of sudden IT disaster. Typically, users practice the 3-2-1 backup method for the best backup experience. These include the following stages typically:

Principle 1: Creating around 3 data copies and keeping them in different physical storage media sections.

Principle 2: Keeping the copies in 2 or more data format types.

Principle 3: Save one of the collected data backups in an offsite location like a commercial-based cloud account.

Let’s understand the stages and the reasons for using them in more detail.

Three Copies

The reason for creating at least three copies of the data in different storage devices is to reduce the danger of losing data if one of these devices gets damaged. To give an example:

  • A network error can block backup data transfer online, but that will not affect local disk-based data.
  • If a virus wipes out a hard drive causing it to stop operating or all data to be deleted, the backup data saved in the cloud account will still stay safe.

Two Storage Mediums

In Synology OneDrive sync, the medium or format refers to the physical style of data representation instead of regular layouts. Keeping at least another copy of the data will help you from storage-specific issues. Thus, this strategy implies that users should store one copy of the files on a hard disk and another for cloud service/FTP.

One Offsite

This principle mentions that users should keep one backup or more than that in an offsite location. Users will keep the secondary backup in another building or room, saving it from physical issues that can cause data loss. One can use the data saved in the secondary location if the primary one gets damaged in situations like:

  • Fire emergency in the facility.
  • Falling and breaking of the hard drive or computer device.
  • External forces are affecting the destruction of buildings, like wars, etc.
  • Data device lost due to theft.
the three two one strategy sequence

Currently, NAS is useful for professionals and regular users to handle multi-level data backup. Additionally, many users are turning to offsite storage services like commercial cloud, e.g., OneDrive. So, you can back up Synology NAS to an external hard drive or focus on OneDrive.
