Hey Shobha,
You can't do better than Aomei Backupper Standard, which is completely free and simple to use: https://www.ubackup.com/free-backup-software.html
Aomei also provides a good collection of step-by-step guides: https://www.ubackup.com/help/
Differential backups are far better than incremental backups, especially if one needs to restore.
Suggest you read through this article: https://davescomputertips.com/simple-guide-to-creating-restoring-images-part-2/
And also part one of the same article: https://davescomputertips.com/simple-guide-to-creating-restoring-system-images-part-1/
Cheers... Jim
Hey Shobha - It depends on how your system is setup. Are you saving all your personal data - Documents, Pictures, Videos, etc. - on the system (C) drive? Or is your personal data saved on a separate drive or partition?
If everything is saved on the system (C) drive/partition, including your personal data, then all you need do is create a system backup and everything will be included.
You can also "explore" an image backup by mounting it and it will display and open under This PC just like any other drive. You can then see exactly what has been saved in the image.
