I have lost the data of my laptop due to sudden crash many times. What is the best way to backup laptop data so that the same will not happen again?
A full Windows PC or tablet reinforcement. The initial two techniques go down specific records, however they're not adequate to recover your PC or portable workstation up and running if your hard drive (or SSD) comes up short, or your PC is stolen. Making a reinforcement of the considerable number of records on your hard drive is otherwise called a 'plate picture' or 'phantom picture'. You'll need programming to do this, yet as with record reinforcement programming there are free and paid adaptations.
Acronis True Image is one well known paid-for bundle, while free alternatives incorporate Macrium Reflect and EasUS Disk Copy (free for hard drives up to 1TB).
