How to automatically sync the contents of a local folder with the contents of a ftp folder?

  • 772

After searching everywhere I have not managed to find a specific answer for my question.

On Windows there is an application called FTPbox that will automatically sync a local folder with an ftp one every set period of time.

My question is, how do I achieve the same thing using Ubuntu? The main thing is here that I dont want to have to do it manually. It needs to be a totally automatic process with no human intervention required (obviously I will have to set this up if that classes as human intervention LOL).

Many thanks in anticipation for helpful answers.

    First solution

    Install lftp

    sudo apt-get install lftp

    after that create script

    #!/bin/bash
HOST='mysite.com'
USER='myuser'
PASS='myuser'
TARGETFOLDER='/new'
SOURCEFOLDER='/home/myuser/backups'
 
lftp -f "
open $HOST
user $USER $PASS
lcd $SOURCEFOLDER
mirror --reverse --delete --verbose $SOURCEFOLDER $TARGETFOLDER
bye
"

    Save it on some place with name upload.sh. Give it +x permission.

    sudo chmod +x /path_to_script/upload.sh

    Setup crontab to run this command on every x period of time

    For editing crontab run

    crontab -e

    For running command on every 5 min code is

     */5 * * * * /path_to_script/upload.sh

    on every hour

     0 */1 * * * /path_to_script/upload.sh

    to run on 4 am

     0 4 * * * /path_to_script/upload.sh

    Solution two

    Create a small and easy script called lftp-script that LFTP can read:

    open ftp://username:[email protected]
mirror --reverse -v --only-newer /home/local/path/ /website.com/public_html/

    Finally you can run LFTP and start the synchronisation. Set crontab like I write but put command

    lftp -f /path/to/lftp-script

    something like this

     */5 * * * * lftp -f /path/to/lftp-script

    Solution three

    Install curlftpfs

    sudo apt-get install curlftpfs

    you need to do in order to mount ftp locally is to to run these commands create dir witch will be sync-ed

    mkdir hostr

    mount remote ftp dir to local

    sudo curlftpfs -o allow_other ftp://user:[email protected] host

    user:pass is the username and password to log into ftp account.

    You can add curlftpfs to fstab for automatic mounting by using this line :

    curlftpfs#user:[email protected] /mnt/host fuse rw,uid=500,user,noauto 0 0
