If you've been using SD cards for a while, you know that they are not infallible. An SD card can become corrupted due to physical damage, software errors, human error, or other factors. When this happens, you may lose access to all of the data stored on the card.

Fortunately, there are ways to backup and restore SD cards so that you can recover your data if something goes wrong. In this article, we'll show you how to backup and restore an SD card on Android, PC, and Raspberry Pi. 

Ⅰ. What Is SD Card? Three Types of SD Cards You Should Know

SD cards are small, portable storage devices that are often used in digital cameras, camcorders, and smartphones. SD cards are a category of memory card for storing data. There are currently three sub-types of secure digital cards: SD, SDHC, and SDXC, but they are all commonly known as SD cards.

Memory cards of the three types come in a variety of sizes and speeds, which can be confusing for some people. Here's a quick rundown of the different types of memory cards:

  • Secure Digital (SD) cards: These are the most common type of SD cards. They come in three different sizes: Standard SD (32mm x 24mm), Mini SD (21.5mm x 20mm), and Micro SD (15mm x 11mm). Standard SD cards are typically used in digital cameras, while Mini SD and Micro SD cards are used in smartphones and other portable devices. (microSD card is previously known as TF card. Know better at TF card vs. SD card→)
  • Secure Digital High Capacity (SDHC) cards: These cards are similar to standard SD cards, but they have a higher capacity (4GB to 32GB). They are typically used in digital cameras and camcorders.
  • Secure Digital Extended Capacity (SDXC) cards: These cards have the highest capacity of any SD card (64GB to 2TB). They are typically used in high-end digital cameras and camcorders.

Take a glance at the main types of memory cards: SD card, SDHC card, and SDXC card

Besides the three types, you may have heard of SDUC cards, which are designed to cover cards ranging from 2TB up to 128TB. It's a newer specification that's not widely used at the moment.

Ⅱ. SD Card Application and Trends in 2022

Now that we've gone over the different types of SD cards, you might be wondering what devices are still using them. While many newer devices are starting to use other types of storage (such as microSDXC), there are still a few devices that rely on SD cards.

  • Digital cameras: Many digital cameras continue to use SD cards for storing photos and videos. Some newer models are starting to use other types of storage, such as microSDXC, but SD cards are still a popular option.
  • Camcorders: Like digital cameras, camcorders often use SD cards for storing video footage for filmmaking or vlogs. Again, some newer models are starting to move away from SD cards, but they remain a popular option.
  • Smartphones: A few smartphones still use SD cards for expandable storage, especially those high-end Android smartphones which start supporting 8k video recording in 2020. Nearly 70% of all digital media consumption goes to a mobile device. However, most newer smartphones (such as the iPhone) do not have this feature.
  • Consoles: Gaming consoles, such as the Nintendo Switch, and Steam Deck, use SD cards for storing large game downloads, patches and updates, to ensure the gaming performance won't be affected by insufficient memory.
  • VR headsets: Virtual reality headsets, such as the Oculus Rift and HTC Vive, use SD cards for storing VR content. It is said that a typical interactive VR application can generate about 1TB of data per hour.
  • Dashboard cameras or dash cams: Being a part of safety technologies, dash cams use SD cards to store video footage of car journeys as vehicles don't have built-in memory to store the recorded footage.
  • Drones: Drones are playing a role in data collection while flying high up in the air, it requires robust storage solutions to ensure performance. And, that's to be advanced SD cards of big brands like Samsung, SanDisk, Delkin, or Lexar.

We don't name all the devices that require SD cards, SDHC cards and SDXC cards for expandable storage,  but you get the idea. While SD cards are slowly being replaced by other storage solutions like eMMC, they're still widely used in many devices. With the worldwide COVID-19 pandemic still going on, people are developing hobbies in photographing, vlogging, playing games, and VR traveling which all heavily depend on memory card storage. So the demand for SD cards will keep rising in 2022.

Ⅲ. Now, You Got 100 Reasons to Back Up SD Card

SD card is universally applied in digital products and the market share is still growing, so it's of great significance to command the basic skills of making backups and maintaining a healthy state of your SD card.

On the one hand, SD card backup is a precautionary measure that deserves your attention. On the other hand, a backup of the SD card is essential when something goes wrong with your SD card and needs to be repaired. Most of the time, we use "formatting" to repair a corrupted or damaged SD card, and disk formatting is the reconfiguring process of the SD card for initial use, which will erase all data on it.

Not limited to repairing SD cards, disk formatting is an effective solution to solve the incompatibility issue of SD cards that Android can not recognize, PC, or other operating systems and devices due to the improper FAT32, exFAT, or NTFS problems.


Disk formatting can help repair common SD card corruption problems, but it will erase data on the SD card, making it essential to know how to back up the SD card before formatting.

Ⅳ. How Do You Back up SD Card?

Since the SD card is set to be removable from any digital device, so when doing backups, we usually copy the data from the SD card to another place, which can be another SD card, a larger USB flash drive, an external hard drive, a computer or a cloud app/drive! Any spare storage location that is available to you can be a backup destination.

Then speaking of SD card backup, there are multiple ways to make it happen. For example:

  • Manual copy and paste
  • Upload to cloud
  • Transfer SD card data to computer
  • Create a backup image
  • Clone SD card

Among all these implementations, some require the help of a computer, while some can be done on your Android smartphone. Let's go through the complete guide on how to back up SD card photos and videos with or without a computer.

Ⅴ. How to Backup SD Card on a Computer

By taking out the SD card and connecting it to a computer, you can select any of the following methods to make a worry-free SD backup to your preferred location.

What you need:

1. Insert SD card into your PC: Plug it into the proper card slot, which is located either directly on the PC's console or via a memory card adapter attached to a USB port.

2. Check the SD card connection: Usually, Windows will instantly recognize the SD card and mount it into the computer system, so you can browse the SD card content to view and edit by opening the Windows File Explorer. 

Option 1. Copy and Paste
  • Advantages: Zero cost; 100% copy source files without date, size, and properties change
  • Disadvantages: Cannot work for programs and system files; time-consuming for large files copy; cannot paste copied files to a network drive or cloud
  • Backup Security level: Low

To summarize, the manual method of copying and pasting SD card files on a computer is suitable for 2GB~8GB SD card backup. SD card that contains massive data over 16GB, this kind of backup method is too elementary to be good.

Step 1. Double-click the SD card in File Explorer. Here are some hotkeys for you to select some or entire files in the first place.

  • Hold Ctrl and selectively click on the files you want to back up.
  • Press Ctrl + A to select all files on the SD card

Step 2. If you're going to save the copy to a local drive on your PC, or another removable storage drive, here's a tip for you. Create a new folder named "backup" or something you're familiar with on that drive, and press Ctrl + C and then Ctrl + V to paste it there.

Option 2. Sync SD Card Files to OneDrive
  • Advantages: Backup accessible on multiple devices after login
  • Disadvantages: 5GB storage is free

Since you're using a Windows computer, a OneDrive folder is created on your PC above the This PC folder. OneDrive is the Microsoft cloud service that connects you to all your files. It lets you store and protect your files, share them with friends, and, most importantly, access backup files from anywhere on all your devices. So, cloud storage is an excellent place to go when it comes to backing up photos and videos, which are usually large files.

Step 1. For the first time using OneDrive, you'll need to register, log in to it and complete the setup with the on-screen guide.

Step 2. Next, the backup process is all about another copy and paste. Select SD files, and copy and paste them (drag and drop also works) to the OneDrive folder. That'll be done.

EaseUS free backup software is universally acknowledged as the most user-friendly yet powerful in doing all kinds of backups. It can connect to your cloud account of Google Drive, OneDrive, and Dropbox as well, so you can still keep the SD backup to the cloud.
