Legend

  • ^1 Windows/Linux/Mac - Supported operating systems for thick client (native binary application), which provide background data transmission and setting services.
  • ^2 Personal Encryption - The user needs to manage their own encryption key or password. If they lose it, there is no way to access the data. The service provider cannot access the user's data even if required by the government.[72][73] Backup service providers often claim that no one can access the users data even though they themselves could if forced to do so, so entries claiming support of this feature should always have a supporting reference. If the backup service has a password recovery or reset mechanism that allows a user to access their data when they lose their password or key, that proves they do not have personal encryption.
  • ^3 Payment method
    • L - Pay per computer. Additional fee for storage over a threshold.
    • U - Pay per computer. Storage per computer is unlimited.
    • M - Pay per unit of storage, but unlimited computers may share that storage.
    • B - Bandwidth capping or limits are used on accounts.
  • ^4 Net drive - Network drive on file server supports some protocols (FTP, SMB, NAS,...)
  • ^5 P2P storage - data spread over many computers based on Peer-to-peer net advantages
  • ^6 Sync - Synchronization between computers, and/or mobile devices (PDA, MDA,...)
  • ^7 Public Internet file hosting -
  • ^8 Restore via physical media -
  • ^9 Server location - country where physical servers are located
  • ^10 Still in Beta version
  • ^11 Whether the desktop client (if available) can detect and upload changes without scanning all files
  • ^12 Many backup services offer a limited free plan, often for personal use. Often it is possible to increase the free backup limit through coupons, referrals, or other means that are not included in this column. This column also does not include free trials that are only available for a limited period of time.
  • ^13 External hard drive support - Can refer to an alternate backup destination or whether the service can back up external drives.
  • ^14 Hybrid Online Backup works by storing data to local disk so that the backup can be captured at high speed, and then either the backup software or a D2D2C (Disk to Disk to Cloud) appliance encrypts and transmits data to a service provider. Recent backups are retained locally, to speed data recovery operations.
