DropBox

DropBox is a free program that allows to create a DropBox file in multiple computers and all computers with that file will be updated each time it connects to the internet with the info that has been put into the files. Also a backup copy will always be stored in http://www.dropbox.com/ so you can check there, download or recover the archives.

It is completely free to a maximum capacity of 2GB, though it can be increased by paying a fee.

I'll probably look into the problem and us it as a backup file.
