rsync is probably the simplest way to sync data between two computers, or even the same computer. Now that I have plenty of storage on my desktop, I can take backups from the laptop. So I tried out rsync.
There are a lot of howtos out there, telling you to schedule backups and stuff. But they seemed somewhat complicated, and I didn't really want scheduling...The laptop runs at irregular times.
So whats the simplest, no-shit solution for rsync? Its grsync!
Ok, then I saw what commands its running on the terminal, and made a shellscript :)
On Ubuntu, install grsync by running: sudo apt-get install grsync
