Network attached storage (NAS) devices are becoming more popular with small and medium businesses. If you have decided to backup your network attached storage, it will quickly become apparent that there are many choices, each with its pros and cons. This fact makes choosing a cloud backup solution for NAS difficult. Here is how to choose the best provider for your needs and a list of the top best providers of NAS backup in the sector. 

Backup NAS Features to Look For

Here are some of the features you should look for when purchasing an online backup solution for your network attached storage: 

  • Security: When you send data to the cloud, your primary concern is, first and foremost, data security. The NAS backup solutions should use Advanced Encryption Standard (AES) 128-bit encryption as a minimum. It is even better if the platform offers private encryption keys. You should also consider whether the solution uses multi-step login verification to prevent unauthorized logins. 
  • Storage space: Every business has unique needs, but ideally, the base plan should offer a storage space that’s adequate for your basic needs.
  • Auto backup options: Your provider should provide NAS online backup services that are automatic (continuous or incremental). You should be able to set a backup schedule on a daily, weekly, or monthly basis. In addition, it must offer fast and simple file retrieval so you can restore your files quickly and easily in the event of a disaster.
  • Privacy and Universal Compliance:  NAS backup solutions must value NAS user privacy. However, it isn’t easy to find an online backup service that doesn’t collect and store personal data in some form. Look for providers that don’t voluntarily share your personal information with third parties without your express consent except for legal reasons. NAS online backup providers must also comply with several federal and international regulations. These include HIPAA, SOX, California Consumer Privacy Act, COPPA, FERPA, GLBA, the Gramm–Leach–Biley Act (GLBA), European General Data Protection Regulation (GDPR), and many others. This ensures your business is compliant with privacy regulations in the US and the rest of the world.
  • Versioning: NAS online backup providers should provide users with versioning as part of their base plan. This allows you to recover files from previous revisions easily. For example, if accidentally delete a file by mistake. You can revert to the file’s earlier version and get it back as if nothing ever happened.
  • Mobile app: NAS providers should provide NAS users with a mobile NAS app to enable easy, on-the-go file access, retrieval, and sharing.

How to Choose an Online Backup Provider

In addition to the feature we mentioned above, there are also several additional considerations when choosing an online backup for NAS. These include:

  • Ease of use: You shouldn’t have to need advanced technical skills to use the platform. It must have an intuitive design and have a gentle learning curve to ensure you can set up quickly and use the platform smoothly.
  • Support: Your NAS backup provider must have excellent support. You should be able to get assistance via fast omnichannel support.
  • Speed: The provider should maintain a high upload speed during backups and you should be able to see the NAS storage performance statistics.
  • Value for money:  Finally, the price should be reasonable for the features you’re getting. For good measure, ensure there is a free trial to let you test the online backup before committing.

When choosing an online backup service, consider which features are most important to you.
