Toda vez que tento executar, sudo rsnapshot -v alpharecebo esse tipo de erro (ocorre em todas as entradas de backup que tenho):
ERROR: /usr/bin/rsync returned 255 while processing [email protected]:/etc/

- Sim, rsync instalado no servidor e nesta máquina
- Sim, o rsync funciona se eu tentar copiar manualmente alguns arquivos com essas credenciais de root do remoto
- Há uma coisa que pode ser potencialmente isso. Quando tentei executar o comando errored out, ele exigiu aspas em torno dos argumentos para o
rsh. Caso contrário, ele lançaria um erro de sintaxe. Mas não tenho certeza de como forçar o rsnapshot a fazer isso. E se eu executar o comando errored out com aspas em torno da chave rsh, ele também apresentará um erro com o código 255. - O firewall não bloqueia o ssh.
- O servidor permite apenas autenticação de chave pública
- Eu hospedo meu servidor Ubuntu no Vultr

# If enabled, rsnapshot will write a lockfile to prevent two instances

# When sync_first is enabled, it changes the default behaviour of rsnapshot.
# Normally, when rsnapshot is called with its lowest interval
# (i.e.: "rsnapshot alpha"), it will sync files AND rotate the lowest
# intervals. With sync_first enabled, "rsnapshot sync" handles the file sync,
# and all interval calls simply rotate files. See the man page for more
# details. The default is 0 (off).
#
#sync_first 0
# If enabled, rsnapshot will move the oldest directory for each interval
# to [interval_name].delete, then it will remove the lockfile and delete
# that directory just before it exits. The default is 0 (off).

# Number of rsync re-tries. If you experience any network problems or
