  • Content-defined chunking that survives files being renamed, moved or shifted around
  • Authenticated AES encryption, so an untrusted backup server only ever sees ciphertext
  • The newest backup is a plain mirror you can read without the tool
  • Reverse deltas keep history cheap while the current copy stays instant
  • Primarily a Unix tool; on Windows it needs WSL or Cygwin rather than a native build
  • Borg 2 is still in beta, ships breaking changes between betas and should not hold production backups
  • No client-side encryption
  • Restoring very old versions means replaying many increments
