It's not hard to safeguard your data, even when it's in plain sight. You simply need to learn to encrypt files or folders using free software. You can then put those encrypted files/folders in cloud storage, USB external hard drives for backup purposes. It all starts with secure passwords you can remember or save in a password manager.

Did you know that if data is encrypted and a data breach occurs, you are not obligated to report it? This is the power of data encryption and can potentially spare you and your employer from unnecessary litigation and expense. This is known as an encryption safe harbor.

Texas defines a data breach in terms of sensitive personal information only if the data items are not encrypted (Source: Data Breach Charts, Baker-Hostetler).

The concept of “Safe Harbor” refers to specific actions that an individual or an organization can take to show a good-faith effort in complying with the law. This good-faith effort provides a “Safe Harbor” against prosecution under the law (source).

Encrypting files with AES-256 can be done with a variety of tools. Here are a few you can use that are free. A few tools include:
7zip for Windows - This is a zip/7zip compression program that combines multiple files into one. Think of it as putting a folder of files into ONE file that is compressed for space and encrypted for security. Other, less bare-bones option include Zipware and/or PeaZIP.
Keka Zip for Macs - This is the same thing as 7zip but for Mac computers.
Paranoia's Secure Space Encryptor (SSE) - Here is (what I think) is the best cross-platform encryption tool available. It works on the most platforms (e.g. Android, Mac, Windows). One of the features is that it can take a folder of files and encrypt them all into ONE file.
FileLock.org - A browser-based solution that works well for Chromebooks. Encrypt individual files via your web browser.

Making backups can be hard because it requires a small level of technical expertise and it can take time. You have to first know how to back up. Check out questions to the right.
Do you use a USB flash drive?
Do you back up to the cloud? Even with plenty of cloud solutions (e.g. Dropbox, Google Drive, OneDrive), most don’t back up.
How do you save documents to your hard drive?
How do you secure/encrypt your data?
From ransomware to simply human error, it's easy to lose data. That's why it's important to make regular data backups. Most people don't know how, so they tend to rely on cloud storage or nothing.
From ransomware to simply human error, it's easy to lose data. That's why it's important to make regular data backups. Most people don't know how, so they tend to rely on cloud storage or nothing.
One way to avoid that is to get a USB external drive (2 terabytes is plenty. USB external drives last three to five years on average, so you may want to invest in one every three years to backup your data). You can use free tools to automate backups.
