Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Backblaze

  • Personal Backup is $99 a year billed annually, with no monthly option
  • Web restores are capped at 500GB per request
  • Forever version history is a Business tier add-on rather than included
  • Administrative controls and SSO are Business features
  • Backs up user data from a computer and attached drives, so NAS and server backup are not covered by the personal plan

Upstash

  • HTTP-based REST API only, no TCP connections means higher latency than self-hosted or connection-pooled Redis
  • Rate limiting occurs when traffic exceeds configured budget cap or request limits
  • Kafka service discontinued in March 2025, requiring migration to Upstash Workflow or alternatives
  • Limited Redis feature support compared to self-hosted Redis or Redis Cloud
  • High-request-volume workloads can accumulate significant costs due to per-request pricing model
