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


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


lftp -f "
open $HOST
user $USER $PASS
mirror --reverse --delete --verbose $SOURCEFOLDER $TARGETFOLDER

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:password@website.com
mirror -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:pass@ftp.example.com 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:pass@ftp.example.com /mnt/host fuse rw,uid=500,user,noauto 0 0
