Lnxgeek.org Wiki - Freedom of choice, I choose Freedom

Prereq:

• A ftp account
• Create a local directory you want to synchronize/backup
• Create a directory on the ftp server you want to upload the content to

Tools:

sudo apt-get install fsniper lftp

Script:

#!/bin/bash

trap "rm /tmp/ftpsync.lock" SIGINT SIGTERM

if [ -e /tmp/ftpsync.lock ]
then
  echo "ftpsync already running.."
  exit 2
else
  touch /tmp/ftpsync.lock
  lftp domingo.dk -u ftpuser,ftpuserpass << EOF 
lcd /home/tdd/FtpSync 
cd FtpSync
mirror -R -e
quit
EOF
  rm /tmp/ftpsync.lock
  exit 0
fi

fsniper configuration file (~/.config/fsniper/config) :

delay_time = 60 
delay_repeats = 0

watch {
  /home/tdd/FtpSync {
    recurse = true
    * {
      handler = /home/tdd/ftpsync.sh
    }
  }
}

Getting going: First time running to get a feeling on how it works out, e.g. fixing any errors

fsniper --log-to-stdout

When things work:

fsniper --daemon
