Clonezilla Backup Software Freezes on Boot

Sounds like a bad Image unable to load the kernel or the kernel not being compatible with the CPU architecture on the system

1. Making an iso backup of my system

I would recommend to use a disk imaging tool like Clonezilla, which can backup the complete contents of your disk into an image, which can be stored on a USB drive, another disk, a network share, or even a writeable DVD.To use it, Download the current stable version, write the ISO to a DVD or USB stick, and boot it, and follow the instructions to create an image of the entire local disk (There's plenty of tutorials, too). You will then have a compressed image, which you can later restore onto the system, using the same clonezilla DVD or bootable USB. (You can even put Clonezilla and the image on the same USB stick for subsequent restores).If you want to make an actual installable ISO of your system, there are various tools for this, such as SystemBack, however, I have not tried any of these myself

2. what is the advantage of Image based backup versus file based backup

Imagebased backups will allow you to create an exact image of what your harddisk was at the time of the backup. If you restore the image, not only do you get your files back, but if that partition also has your windows installation, your windows installation will become that of when the backup was made.Why is this important? If your windows does not start anymore, you can go back to that specific point easily. Filebased backups do not have this luxury. Only the files are backupped. However, the biggest difference between file backups and imagebased backups is when you backup often. An image based backup is usually a full backup, and thus it always takes very long to make. A filebased backup can skip backing up all files that are already in the backup and only backup the changes (differential/incremental backups). So depending on your needs, you need either an image based backup, a filebased backup, of both.If you need to be able to restore windows to an earlier point, you will need an image based backup. If you need quick backups, you will need a filebased backup. That said, there are backup solutions that can do both in the same program. They create images, but can make incremental backups too, and they often also can extract the files from the image.In most situations, filebackups are always used, and the imagebased backup is supplementary. You would typically use an imagebased backup in case you are going to make drastic changes to your windows install and do not want to risk failure (you can always go back to before you started). A filebased backup would typically be used to ensure your most important files will always exist. These can be your office documents, but some have their photo's only in digital form nowadays and then of course they are very precious.

3. Create a Virtual Machine as a backup

Yes you can create a virtual hard diska for a backup. There are several tools out there that can do this. One example from Microsoft is Disk2VHD. Many VM platforms support Microsoft's VHD format, which is convenient. The problem with this type of solution is you need another PC to run the virtual machine, if your current machine is no longer working. If you dont have another PC, then you have to return your affected PC to a workable state. And once your virtual machine is up and running, you still have to return the affected machine to its previous state. These time consuming extra steps are the reason why the following is a better choice.A better solution would be creating images of your machine. Programs like Macrium Reflect Free allow you to make complete images of your machine, as well as create bootable media to restore that image directly to the affected PC. No secondary PC is required, or the need to fix your affected PC

5. how to do file backup?

A flashdrive is great for backup but it's only so big and pictures take lots of room. You should get an ide to usb adapter and another hd. It does not have to be too big say 20-30 gig and with the adapter, you can backup every picture you have on that hd. You can get them both for about $50.00 and use it for all your backup.
