[40] Walk through – Camera SD Card picture recovery using Ubuntu and Foremost.

I deleted the images from my cameras SD card as I knew I had downloaded the images prior. What I did not know at the time was that one of my family members took additional photos! I now needed to find a way to recover these images. Well I did manage to recover all the photos. After this ordeal thought it would be valuable to share the process I used to recover data with the community. Hope you get value out of this walk through! 😉

—Guide Start Here–

Foremost Installation

$ sudo apt-get install foremost

Create the disk image of the SD Card using DD

$sudo dd if=/dev/mmcblk0p1 of=/home/hendgrow/file_recovery/images/Camera_SDCard.img status=progress

Using Foremost to recover the images from the SD card image we just created.

$ sudo foremost –t png,jpg –i /home/hendgrow/file_recovery/images/Camera_SDCard.img

Need to change the folder and file permissions as we executed the command as root.

$ sudo chown –R hendgrow:hendgrow /home/hendgrow/file_recovery/output/putput/

Thats It

[35] Ubuntu Samba Server Install Guide with Apple Time Machine Support

The guide or steps used in this tutorial can be found in the YouTube description section of the video guide.

This guide was done as a response to a request by one of our YouTube subscribers to create a tutorial on how to install the samba server role that supports Apple Time Machine on Ubuntu server 20.04 LTS. The request came after they watched a similar tutorial we did based on openSUSE 15.2 Leap.
