: Please advice me what to do next. Thank you in advance.

Please make sure that the rsync daemon is actually running as root,
that there are no syslog messgaes complaining about permission
problems, etc.

Also make sure that the area you are trying to write to isn't NFS
mounted (which denies writes to root by default), or has immutable
file attribute set (see ls -o for a list of flags).
