About the backup method of the SD card used for Raspberry Pi
I will introduce one method of ~~ 2 ~~. The articles that I referred to are listed in the related links at the bottom of the page.
| Method | merit | デmerit |
|---|---|---|
| How to back up the entire SD card | Easy backup method | Reading and writing to the free space in the SD card occurs, and the backup time and storage efficiency are poor. Also, the life of the SD card tends to be shortened. |
| How to back up only the space you need | Good backup time and storage efficiency | Backup procedure is a little complicated (requires basic knowledge of file system) |
I decided to leave a backup method when working with Raspberry Pi in the article. HDDs and SSDs are becoming cheaper, so if you have a size of about 32GB/64GB, you shouldn't have any trouble backing up the entire space, but since you shouldn't back up the free space, only the necessary space I will also introduce the backup method of.
To write the backed up file to the SD card, click the "Write" button.
$ sudo mkdir /mnt/d $ sudo mount drvfs D: /mnt/d
★ I can mount the drive, but I can only see/boot, so I gave up.
I introduced the backup method of the SD card used for Raspberry Pi. I didn't have a Linux environment at hand and tried to back up with WSL, but I investigated but gave up because I could not solve the problem that the Linux file system could not be seen. If a solution is found or the Linux environment is set up, I would like to add a method to back up only the necessary area.
The surveyed content (article) is posted on the related link.
