You will be losing all of your data if your system isn’t backed up.
It will happen at the worst time possible.
You won’t have the money to fix it.
If you don’t already have a way to backup your pc,then you need to get one.
A free program that you can use is Cobian Backup.
It can be scheduled to do regular backups of your data.
Backup options available with the program:
Full backup: A backup of everything.
Differential backup: A backup of everything that has been modified since the last FULL backup.
Incremental backup: A backup of everything that has been modified since the last backup.
