  • Several machines can back up to one bucket and share deduplicated data with no server between them
  • Chunks are stored individually, so any storage with basic file operations works as a backend
  • Content-defined chunking that survives files being renamed, moved or shifted around
  • Authenticated AES encryption, so an untrusted backup server only ever sees ciphertext
  • Licence is not open source; commercial use and the web interface are paid
  • The free part is a command-line tool, so the friendly front end is the paid one
  • 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
