A quick script using rsync with ssh:
      1  #!/bin/sh
      2  # mirror - Mirror files from RemoteServers to LocalServer

      3  LOGFILE=/data/logs/mirror/`date +%Y%m%d%H%M%S`.log

      4  # Limit the bandwidth on a slow / busy network
      5  BWLIMIT=256

      6  RSYNC="/usr/local/bin/rsync -avze /usr/bin/ssh
--bwlimit=$BWLIMIT --delete"
      7  LocalDir=/data/backups/servers

      8  echo Start: `date`
      9  echo LogFile: $LOGFILE

     10  # Start a new logfile
     11  echo Starting at: `date` > $LOGFILE

     12  echo RemoteServerA >> $LOGFILE
     13  $RSYNC RemoteServerA:/src/dir/
$LocalDir/RemoteServerA/dst/dir >> $LOGFILE

     14  echo RemoteServerB >> $LOGFILE
     15  $RSYNC --exclude 'logs/' RemoteServerB:/src/dir/
$LocalDir/RemoteServerB/dst/dir >> $LOGFILE

     16  echo  >> $LOGFILE
     17  echo Ending at: `date` >> $LOGFILE
     18  echo Stop: `date`
