I mistakenly deleted some important zip files from my micro-sd card. I want to do data recovery on my micro-sd card. Before doing that I want take image backup of my sd card data, so that I can have backup of my micro-sd card data in case of any crash. From the link askubuntu I came to know that dd_rescue command will do the job.

This link GNU ddrescue Manual provide few examples for how to do data backup. But I couldn't find the exact command to take data backup from sd card to a image file.

What command I need to provide to take image backup of my micro-sd card?

Thanks for the support

Since you have no errors on the device you don't have to use "dd_rescue". "dd" is sufficient.

I don't know your system configuration. Therefore I suppose your SD card is device /dev/sdx. To create an image using dd please enter the following commands:

dd if=/dev/sdx of=backup-image.img

It's a good idea to unmount the partitions of the SD card before.

I hope this helps?
