The basics
You don't need to be technical, you just need to have a copy of your own data.
Step one is backups. After that you can look for EU or local alternatives.
Your photos, documents, and emails live on someone else's computer. If that company has problems, or locks you out, or shuts down - your data could be gone.
Things that can go wrong:
The solution is simple: keep your own copy on a drive you own.
One backup is not enough because hard drives fail and things get lost. Always have two copies in different places: one external hard drive at home, and another drive stored somewhere else.
If one fails, you still have the other.
Most services let you download everything you've stored with them.
Search for "[service name] download my data" or look in Settings for "Export" or "Download your data".
A regular hard drive (HDD) is fine for backups since SSDs and memory have become very expensive. For storage that sits on a shelf, HDD works great and costs less. Look for at least 1TB, a USB connection so it works with any computer, and a known brand like WD, Seagate, or Toshiba.
Your backup drive contains sensitive data like photos, documents, and passwords. If someone finds or steals the drive, they can access everything.
The solution: encrypt your drives. Both Windows (BitLocker) and Mac (FileVault) can do this. When you plug in the drive, you enter a password to unlock it.
Write down the password and store it in a safe. If you forget it, your data is gone forever.
Do a full backup every few months and set a reminder in your calendar.
For photos, do it more often if you take a lot of pictures.
