exxos's Atari, Amiga & retro forum

Looking for some guidance, I'd like to create a backup disk image of the sd card in my Ultrasatan.

I've used HDD rawcopy before with my Amiga drives or used WINUAE to create a disk image, but as I'm new to the Atari, I'm not sure what software or prefix to use , ie .hdf etc to create a working disc image.

I have access to Windows 7 and Ubuntu Linux so any links to software would be appreciated.

If there's a website that goes back to the basics that I should read , please do link me to it.

Thank you

I did use dd to make a backup of a 4gb SD card with about 8 partitions.

Put the sd card in the memory reader and looks at dmesg log to see which /dev/sdx file, for me its usually sda. Then i just do dd if=/dev/sda of=AtariSDBackup.img status=progress . And to restore it to a SD card you swap if with of like this dd if=AtariSDBackup.img of=/dev/sda status=progress .

Works for me.
