Since some time I have been playing around with AeroFS(https://www.aerofs.com/) for a proper datasynchronisation between my devices.
I can’t say anything negative about it so far, it works fast, secure and is highly configurable for everyone.
To give an idea what AeroFS can do:

• Private Syncing, allowed you to sync your devices between all your devices(Android & iOS support comming soon I hope!)
• Unlimited Storage, the storage on your own devices is used and therefor your only limitation!
• Sharing is caring, all your folders are private by default, but you can choose to share them with other AeroFS users
• It’s Secure
  • Every device gets their own 2048bits key, making it very(!!) hard to be impersonated by black hat hackers!
  • These keys are used between your devices to verify their identity
  • These keys are also used to encrypt your data while syncing
• It has a graphical interface for easy configuration, but also a shell client for advanced/scripted configuration

Best thing about this is, you dont have to rely on any public service, except for an Internet connection!
Although for me it is common sense I would like to have it noted that your devices have to be turned on at the same to have them synchronise!!

My Script

Because I like AeroFS a lot, it does what it promises to do and it shows to be stable already in the current Beta stage, I have started to reconfigure my (X)Ubuntu machines to use this as much as possible, so my data is always stored in my personal “cloud” and I dont have to worry whether I put that one file in my AeroFS folder or not. So basically all my devices work on my personal storage cloud.
Therefor I wrote a little bash script to run, that will make the important profile folders(Documents, Pictures, Music & Videos) get moved and linked to the AeroFS folders. That way if I ever save anything in these folders it’s automatically synced between my devices. I also made the script in a way it can easily be extended with more folders.
Below you will find the code, which you can just copy to a textfile and make it executable.(chmod +x [name textfile]) I will try to make this even more userfriendly or make a more extended description of how to do this as soon as possible.
You can configure some of the parameters yourself or just go with the default settings which work with a default (X)Ubuntu installation and a default AeroFS installation.

Little disclaimer, using this script is entirely at your own risk. Although I have tried to built in some checks to see whether everything is alright, I take no responsibility for any damage this script could cause.
