Hi Oden. I'm Greg, 10 years awarded Windows MVP, specializing in Installation, Performance, Troubleshooting and Activation, here to help you.
Solution for what? Are you asking about Backup solutions? If not then please clarify so I can help you better.
The safest and most reliable backup method is to sort your files into their User Folders (Documents, Desktop, Pictures, Downloads, etc) and periodically drag or copy them to external or another hard drive. See tips for copying large groups of files here: http://www.pcworld.com/article/2086566/the-many...
Then have one other Cloud backup so your files are safe from ransomware, fire and theft and easily accessible via the internet just like email. Some suggestions to help ease into this habit:
You can drag or copy 5gb for free into OneDrive app to store in the cloud where they are safe from fire and theft. You can also choose to sync the Desktop, Pictures and Documents folders (only) in OneDrive app Settings > Backup for real time backup. More here:

If you install Google Drive, you can use their new Backup to choose ANY User folders (Documents, Pictures, etc.) to sync up to 15g for free to their cloud in real time. You can also drag/copy selected files into Drive folder. More here:

Besides your files you should back up a System Image to use in place of reinstall in 20 minutes. The best free alternative is Macrium:

There is an easy way to mount the System Image to extract files if needed. Some prefer to move their User folders off of C to make the image smaller and so they stay current if you need to re-image C. Here's how to move User folders to a data partition you create:

This way if Windows ever becomes irreparable you can restore C in 20 minutes from recovery media, and your files will be current and safe in their own separate partition. If they are left on C they will be dated from when the image was taken.
I hope this helps. Feel free to ask back any questions and keep me posted. I will keep working with you until it's resolved.
