What are the best, free solutions and services for backing up data, hosting files, and synchronising on multiple computers?
Hosting online
See
this blog about cloud storage and pricings.
Local Backup
See
this blog for recommend backup programs for both imaging and local files.
If you have other computers you could backup to and do it manually, then FTP using
FileZilla or
Beyond Compare also works well, but you'll likely need to port forward the addresses on your home router, and you may need to use
Dynamic DNS as well.
