Tools to synchronize data and so called clouds are pretty handy to use files on different machines. There are tools with a main server and there are tools that don't need them.
The biggest advantage of having a main server contain your data is that - as long as the server is online - you can sync as you please. You do not need to care which machines are online to get all the files you need. If you are talking about a cloud, this is this.
If you can bare the difficulties ascending due to the mentioned above problems, this is probably a more safe way to "host" files. There is no single server as point of attack with all your data.
