    Some users have reported slower upload speeds for initial backups, which can be a drawback if you need to back up large amounts of data quickly.
  • Complex Interface
    The user interface can be somewhat complex and unintuitive, which might be challenging for non-technical users.
  • Limited Customer Support
    Customer support is not available 24/7, which could be an issue for users needing immediate help outside of business hours.
