As an aside but importantly related to this topic - it's one thing to backup to whatever your backup destination device is, whether local or in the cloud. How many folk actually check to see whether they can actually recover their data by restoring it to another drive on their PC/laptop and checking that it all restored correctly. It may require you to purchase a spare drive at least the size of the one you are backing up and then restoring to that new device. Many people do their backups on a regular basis but have never checked to see whether the data (or image of their working drive) can be restored easily and without any grief. Sooner or later Murphy is going to catch you out if you haven't gone down that path and have clear instructions on how to go about the recovery process and have proven them to work.
Put yourself in the position where something catastrophically happened to your desktop/laptop. Worst case -it's stolen or failed beyond repair. You have to buy a new device - nothing salvageable - now what? How do you get back your system and data to how things were prior to this catastrophic event. Think of all the hours you spent over configuring the device to behave the way you wanted it to including all the apps on it. Can you remember all the steps you took?
Can your data be restored to totally different hardware? This may well be the situation you face having to buy new hardware.
All this needs to be checked out when choosing a backup app.
If you don't know how to restore your data then you are living in la-la land which will ultimately give you a lot of grief when reality kicks in..
