(2022) SD Card Backup and Restore on Android, PC and Raspberry Pi

SD cards, despite their reliability, can become corrupted due to various factors such as physical damage, software errors, human error, or other unforeseen circumstances. This corruption can result in the loss of access to all 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. On Android, PC, and Raspberry Pi, you can backup and restore an SD card, allowing you to recover your data in case of an issue.

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

SD cards are small, portable storage devices used in digital cameras, camcorders, and smartphones. They are a category of memory card for storing data, with three sub-types: SD, SDHC, and SDXC, all commonly referred to as SD cards.

Here's a quick rundown of the different types of memory cards: Memory cards come in three main types: SD, CF, and XQD. SD cards are the most common and are used in cameras, smartphones, and other devices. CF cards are larger and faster, often used in high-end cameras and professional equipment.

• Secure Digital (SD) cards come in three sizes: Standard SD (32mm x 24mm), Mini SD (21.5mm x 20mm), and Micro SD (15mm x 11mm). They are commonly used in digital cameras (Standard SD), smartphones, and other portable devices (Mini SD and Micro SD), with the latter previously known as TF cards.
• SDHC cards are similar to standard SD cards but have a higher capacity (4GB to 32GB), typically used in digital cameras and camcorders.
• SDXC cards are the highest capacity SD cards, ranging from 64GB to 2TB, and are commonly used in high-end digital cameras and camcorders.

The main types of memory cards are SD cards, SDHC cards, and SDXC cards. These cards differ in their storage capacity and speed, with SD cards having a maximum capacity of 2GB, SDHC cards up to 32GB, and SDXC cards up to 2TB.

Besides the three types, you may have heard of SDUC cards, which are designed to cover cards ranging from 2TB up to 128TB, but are not yet widely used.

Ⅱ. SD Card Application and Trends in 2022

Although newer devices are increasingly using other types of storage, such as microSDXC, there are still a few devices that rely on SD cards.

• Digital cameras often use SD cards to store photos and videos, although some newer models are starting to adopt microSDXC as an alternative.
• Camcorders often use SD cards to store video footage for filmmaking or vlogs, although some newer models are starting to move away from them.
• Some high-end Android smartphones still use SD cards for expandable storage, but most newer smartphones, like iPhones, do not have this feature, with nearly 70% of digital media consumption happening on mobile devices.
• Gaming consoles like the Nintendo Switch and Steam Deck use SD cards to store large game downloads, patches, and updates, ensuring smooth gaming performance by keeping the console's memory free from clutter.
• Virtual reality headsets, such as the Oculus Rift and HTC Vive, use SD cards to store VR content, which can generate around 1TB of data per hour of interactive use.
• 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 rely on advanced SD cards from brands like Samsung, SanDisk, Delkin, or Lexar to ensure robust storage solutions for data collection while flying high in the air.

The demand for SD cards is expected to rise in 2022 due to the ongoing COVID-19 pandemic, as people develop hobbies that heavily rely on memory card storage, such as photography, vlogging, gaming, and VR traveling.

The global Secure Digital (SD) memory card market is expected to grow from $4.7 billion in 2022 to $6.5 billion in 2028, at a compound annual growth rate (CAGR) of 5.2%.

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

The SD card is a widely used component in digital products, and its market share continues to grow. To ensure its optimal performance and longevity, it's essential to master the basic skills of making backups and maintaining a healthy state of your SD card.

SD card backup is a precautionary measure that deserves attention, and a backup 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, which involves reconfiguring the SD card for initial use and erasing all data on it.

Formatting an SD card can resolve compatibility issues when it's not recognized by Android, a PC, or other devices due to problems with the file system, such as FAT32, exFAT, or NTFS.

Ⅳ. How Do You Back up SD Card?

When backing up data from an SD card, it's common to copy the files to another storage location, which can be another SD card, a larger USB flash drive, an external hard drive, a computer, or a cloud app/drive. Any available spare storage can serve as a backup destination.

Here are the ways to make SD card backup happen:

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