Conclusion
For privacy-first households, Sync.com or Proton Drive offer the best zero-knowledge experience. pCloud's lifetime plans are unbeatable if you're willing to pay upfront.

Frequently Asked Questions
Sync keeps a folder mirrored across devices and the cloud — if you delete a file locally, it deletes in the cloud after sync. Backup is one-way archival storage — files stay backed up even after local deletion. You need both: sync for working files, backup (like Backblaze) for disaster recovery.
Yes for sensitive data (financial records, legal docs, family memories). Zero-knowledge means even the provider can't read your files — they only hold encrypted blobs. Tradeoff: they can't help you recover a lost password. Use a password manager to never lose access.
Most households: 100-500GB if cloud storage is mainly documents and photos. Heavy photo/video families: 2TB+. Creators and developers: 5TB+. Always budget 2-3x your current needs — storage habits creep.
