  • Every snapshot is a browsable directory, so restoring is just copying a file
  • Hard links make dozens of retained snapshots cheap in disk space
  • Content-defined chunking that survives files being renamed, moved or shifted around
  • Authenticated AES encryption, so an untrusted backup server only ever sees ciphertext
  • No encryption or compression of its own
  • Hard links mean the backup destination must be a filesystem that supports them
  • 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
