While running.
Click on ~/.config, ~/Pictures, so on and so on. Compress, then move the compressed file to a back up location. External Drive, SSD, Google-Drive, whatever.
Once this is done, it does not need to be done anymore. That's the problem with many back ups, is you must redo it each and every time.
After that has been done, periodically move changes to the compressed directory to replace the old - with drag and drop.
Let's say I change some documents or make a new document in~/Documents.
I just drag and drop the new doc or revised doc to the compressed directory and it will compress and add it. If I am in a hurry or feeling lazy, I'll just drag and drop all contents.
And since I do this when or as changes are made (Most of the time, anyway), my backups are good to the minute, not to last week or even yesterday.
Lastly, it spares the Bloat of backing up things I do not need or even want to save using a Back Up manager.
I got into this habit when I was new to Zorin and had to wipe and reload a lot after utterly destroying the system experimenting.
Finally, I never recommend backing up Root.
