User Case: Can I Backup Synology NAS to Backblaze?

"Is there any way to use Backblaze to back up my NAS? I'm a little worried about my NAS data being lost due to hard drive corruption. Does anyone know how to do it? It would be great if there are detailed steps."

Why Backup NAS to Backblaze?

It is believed that many home users and small businesses choose Synology NAS as their data storage location because NAS as a local data storage service can help users store large amounts of important data, facilitate user collaboration, speed up recovery, make files available 24/7, and achieve unprecedented levels of redundancy.

Many users should have enjoyed all the conveniences brought by Synology DiskStation, but NAS due to its hardware cannot fully protect your data from natural disasters, ransomware attacks, or major hard drive failures. In short, you can store your backups on a NAS for easy access, but NAS by itself doesn't constitute a true backup strategy.
