Hello, I've managed to run rclone to have synced any folder on almost any cloud.
The clouds available are all those listed here: https://rclone.org/

Step 1: Download the necessary files.

open ssh and run those commands:

cd ~
mkdir -p rpi-sync    
wget -O rclone-install.sh https://raw.github.com/pageauc/rclone4pi/master/rclone-install.sh   
wget -O rclone-sync.sh https://raw.github.com/pageauc/rclone4pi/master/rclone-sync.sh   
wget -O rpi-sync/Readme.md https://raw.github.com/pageauc/rclone4pi/master/Readme.md

now we have all the necessary files, but we have to modify rclone-install.sh
run: nano ./rclone-install.sh
Delete all the sudo on the file, at the end you should have something like that:

now let's finish with the commands

chmod +x rclone-install.sh
chmod +x rclone-sync.sh
./rclone-install.sh 

Step 2: Add an account

Go to https://rclone.org/docs/ and pick any cloud service.
The steps don't change for Recalbox (at least for Google Drive, which is what I used).

Step 3: Execute it on start

Now that we can sync saves, it's time to automate it.
We have to create a startup script; run:

cd /etc/init.d/
nano ./S99Sync

Now we will create the startup script

#!/bin/bash
case "$1" in
        start)
# check that is online to run the first sync command
while :
do
        wget -q --spider http://google.com
        if [ $? -eq 0 ]; then
                # Run the command that will execute only once at the start
                # this is for GDive, it will copy every folder and file
                # and it'll delete those that have been deleted
                /usr/bin/rclone sync gdmedia:rpi /recalbox/share/saves/ &
                wait $!
                break
        else
        fi
done
# This is the main loop
while :
do
        # I prefer to have an external script to run my rclone commands
        /etc/init.d/Copy.sh &
        # the wait will make this script wait until the Copy.sh has finished
        # it's important not to run twice any rclone script at the same time
        wait $!
done
;;
stop)
rclone copy /recalbox/share/saves/ gdmedia:rpi
;;
restart|reload)
rclone copy /recalbox/share/saves/ gdmedia:rpi

;;
*)
esac

exit $?

Exit and save that file.
Now we will create the Copy.sh file that will have our scripts

nano ./Copy.sh

This is what I have:

/usr/bin/rclone copy /recalbox/share/saves/ gdmedia:rpi

This copies the new/modified folders/files from /recalbox/share/saves/ to my google drive folder called rpi
You can do whatever you want to be executed all the time there.
Now let's make them executable

chmod +x Sync
chmod +x Copy.sh

Perfect! now if you restart your recalbox.... it won't work.
Even though you can run it from any ssh and it'll work, it won't work itself we have to fix something more

Step 4: Make it work

make sure to do this step everytime that you change your rclone configuration.
You have to copy the rclone.conf from /recalbox/share/system/.config/rclone to /.config/rclone
I did it manually, but you should be able to do it with this command
cp -i /recalbox/share/system/.config/rclone/rclone.conf /.config/rclone

Problems

1. The startup of any game will be from 1 to 15 seconds slower.

Special Thanks

Special thanks to @substring and @voljega for all the help provided to me with this.
And of course rclone for making this possible, and pageauc for making the rclone4pi

Sync more things than saves

I made that to only sync saves, but you are able to sync everything that you want, just change the folder where you want to sync and that you want to sync

Hello, is there any known way to emulate ds with drastic? With retropie works perfectly.
If there isn't, how can I package the emulator (I know there is no apt get) and test it?

@substring It's true I forgot that, is there any way to edit the post? Can't find it though I can for answers.
And yeah it can be risky, I haven't thought about that

@substring Thanks to that I've found that on the daemon, it searched for one .conf on another place. Now I've solved and it's fully working without problem.
If I have time, this weekend I'll make the tutorial for recalbox. If I do it, it'll be at least for GDrive, maybe for onedrive too (can't promise anything as it should be almost the same).

@substring About the rclone, I haven't, I added the full path for rclone and still doesn't work like it does on ssh. The script that calls rclone I have done chmod u+x and it's in /etc/init.d/
Is there someway to see the actual recalbox terminal without having to exit emulationstation and/or from the pc?

@voljega well the other posts' main problem are solved, but as the main thing is not, I haven put [solved] in the title

Hello, my custom start script doesnt execute correctly what my ssh does... its about rclone (uses rsync) and even though it does the infinite and execute the echo and the recallog, the rclone's commands don't, while executing the same file over ssh allows me to do so.
My daemon script works because it calls the other script with the command.
the script that the daemon calls:

#!/bin/bash
rclone copy /recalbox/share/saves/ gdmedia:rpi > /dev/null

edit: I tried without !/bin/bash too

@substring Yeah I want to execute the script:

1. On start, once wifi is enabled.
2. When any game is launched.
3. if possible, when any game is closed

What I wanted to test was if it was connection it didn't matter if it was through wifi or ethernet, I have found an script that I will post here if it works.

Is there anyway to know if wifi is connected?
I need to run a script once wifi is connected for the first time, doing it on the startup it seems that it doesn't work because wifi is not connected yet
