    Hi all, finally I am using manjaro live CD. It has included timeshift and it works fine, no problem here.

    Good that you found out that you like Timeshift.
    I hadn't thought of Timeshift, as I thought you asked for an imaging application, that's why I mentioned Clonezilla alternatives Rescuezilla and Redo Rescue. To my knowledge, Timeshift has more similarity to something like the System Restore feature in Windows than to a true imaging application.
    Moving from Windows to Kubuntu, January 2020, I gave Timeshift some thought as a Windows System Restore equivalent, but I decided Clonezilla imaging was enough for me.

    Does Manjaro live CD support booting on a system with UEFI secure boot enabled? The last time I tried, I believe it was about a year ago, it still did not support booting with secure boot enabled in BIOS.

    Actually, it can. You have to pipe it through .gz using a bash command. An Ubuntu 18.04 LTS live CD is fine for this although I would assume it's the same for 20.04 LTS. It also doesn't copy unused space resulting in a compact image. The images for my lightly filled 256GB drive were around 7GB. Backing up my main server drive with a live cd to an internal drive and then an externally mounted usb drive the syntax would be (my drive locations):
    sudo bash -c “dd if=/dev/sda | gzip > /media/backup/yourimagename.img.gz”
    Quotations are needed as shown and you would have to change sda to the drive you want to image and /media/backup/yourimagename.img. to the location and filename you want to save the backup to and as.

    I should have included the syntax to write the compressed backup image back to the drive:

    gunzip -c /media/backup/yourimagename.img.gz | sudo dd of=/dev/sda

    Of course, again substituting in your correct backup image location, file name and destination drive.
