Safety Tip 1: Vacation is the perfect time to back up your photos, whether you’re staying in your own country or going far away. You might think, “My photos are also in the cloud,” but things can happen there too! A cloud is not a reliable backup, especially if it’s a cloud that only synchronizes. You’re best off doing following the 3-2-1 system. Ensure you have 3 copies of your photos on 2 different media, and 1 in another location. For example, one on your computer, one on an external hard drive, and another on a different external hard drive – in another location (another house). That ‘other location’ can also be in a cloud.
Safety Tip 2: Data blocker. When you’re on a trip, you’ll be charging your phone everywhere —convenient charging stations at the airport, under your seat in the train, in hotels, at campsites, in cafes and restaurants, etc. Charging in public places carries a risk: hackers can exploit those charging spots and install spyware on your phone, and then gather various login details. It’s safer to charge as much as possible with a power bank. Even safer is to buy and use a data blocker. This is a USB plug (sometimes called a USB condom :)), which only allows the power you need to pass through, not data. There are also cable data blockers. Take a look at what they have on Bol.com.
Also, be cautious with free Wi-Fi. Hackers might be at work there too, setting up a fake network to monitor the data traffic of all connected devices.
