BackupFromRsyncd
From RdiffBackupWiki
Hi,
It would be great to have rdiff-backup get it's snapshot from a remote host through a rsyncd daemon. This way, the rsyncd can run read-only as root on the remote host, and all the ssh-key as root problems disappear. For example, it doesn't require the 'PermitRootLogin yes' in sshd_config. But this is probably impossible using librsync...
Note: you may prefer to use 'PermitRootLogin without-password' instead.
