There is a completely different kind of backup. It is very important. That is a partition/disk
Image backup.
The Paragon and Easeus you refer to are for
Image backups.
Image backups are essential if your operating system gets badly infected, or corrupted, or you can't boot in , or the Hard drive fails.
You simply restore the
image - either back to the same partition , or if the HD fails - get a new HD and restore the
image to that.
In a few minutes you will be up and running with the operating system , all the updates, programs, settings , and any of your personal files and folders. Everything that was on the partition/drive will be restored exactly as it was at the time you made the
image.
You can usually also ( as an added bonus ) find and copy back just individual files from the
image , if you need to.
Generally, people make occasional
Image backups - say once a month.
They do separate
file/folder backups more often - once a week ( or perhaps every day if you are writing a novel ).
The reason for that is an
image backup is a larger undertaking - you
could do one every day, but most prefer to do an
image occasionally , then
also do selected
file/folder backups more often - as it there is much less involved in just backing up a few files.
Hope it helps.
