SpiderOak One review

SpiderOak One is for people who rank privacy above price. Files are encrypted on your device before upload and the keys stay with you, so SpiderOak states it cannot read your files, filenames or folder structure. Every plan includes unlimited devices across Linux, Mac and Windows, plus backup, sync, sharing and version history. Backup takes versioned, point-in-time copies of the folders you select, and you can roll back to a snapshot from before a ransomware attack or deletion without the original device. Sync works through a Hive folder or custom folder pairs, and Share Rooms or self-destructing links let you share read-only files with people outside your account. Pricing runs from $6 per month or $69 per year for 150 GB to $29 per month for 5 TB. That makes it expensive per terabyte next to Backblaze or IDrive, and because backups cover selected folders, you have to choose what to include.
