Every time there's a major tech-related incident, it's a good reminder to evaluate your backup strategy. Have multiple local and off-site copies of all data. Daily mirrors to cloud and/or local drives, and quarterly to removable media.
Use optical discs for long-term storage because of their greater stability compared to magnetic media. Use HTL BD-R discs - I can recommend specific models.
Store sensitive material in VeraCrypt volumes.

Backing up only to cloud storage (GDrive, iDrive, etc.) is *not* sufficient because you do not have full control. You need local copies of anything that matters. Also, don't put anything on cloud storage that could be potentially harmful or embarrassing to you or others if it leaked publicly.

Every time I save something I consciously pay attention to make sure it is *not* saving to cloud storage.
I can still understand why people or businesses would, if they have lots and lots of large documents.
But for general at home non-business use, I've never understood the draw.
