bash: line 1: rsync: command not found
rsync: connection unexpectedly closed (0 bytes received so far) [Receiver]
rsync error: error in rsync protocol data stream (code 12) at io.c(232) [Receiver=3.2.7]

Когда BackupPC (или вы вручную) инициирует rsync через SSH, он выполняет следующее:

  * Устанавливает SSH-соединение с клиентом.
  * Запускает на клиенте удаленную команду rsync --server.
  * Если rsync не найден в PATH пользователя backuppc на клиенте, возникает эта ошибка.

Исправление

$ apt update && apt install -y rsync

nano /etc/sudoers.d/backuppc

backuppc ALL=NOPASSWD: /usr/bin/rsync
