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

Carbonite

  • Upload speeds are significantly slower than competitors due to lack of block-level algorithms and multithreading
  • Bandwidth throttling control is limited, preventing users from managing full bandwidth allocation
  • Mobile apps and web access are more limited than sync-first services like Dropbox or Google Drive
  • Uses AES-128 encryption instead of industry-standard AES-256
  • Hybrid backup support is restricted to professional plans, unavailable for personal users
