Where each one falls short

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

Restic

  • Cold storage is not natively supported; restoring from S3 Glacier and S3 Glacier Deep Archive is only available as an experimental feature behind a feature flag
  • A Windows file whose name contains a character Windows treats as invalid cannot be read by restic and has to be renamed
  • Antivirus real-time protection degrades performance on Windows unless the restic binary is added to an exclusions list
  • On large repositories the built-in five minute stuck-request timeout fires during file listing and has to be raised manually with --stuck-request-timeout

Unitrends Backup

  • Pricing is not transparent and requires contacting the company directly for a custom quote
  • Minimum pricing starts at approximately $995, limiting accessibility for very small deployments
  • Unified pricing approach means less flexibility for scaling individual components
