barman + rsyncd instead of ssh+rsync ?

[Frederic Beuserie]

Hello,

in a phone-home scenario, where the ssh layer is already setup up from pghost (ssh) to barman host (sshd), i would like to configure my rsync job to use rsyncd on pghost.

this way i don't have to setup a second layer of ssh / sshd / auth and everything on my pghost to allow barman backup_method to connect back.

something like the streaming protocol where barman talks directly to postgres daemon

anyone already managed to do that ? i guess 'backup_method' to extend with 'rsyncd' protocol ? or some magic syntax to use to "bypass ssh" ?

thanks
