I used to run backups at a place I worked where I would put a DAT tape in at the end of the day and move it to a safe place when it finished the next morning. Now the quantities of data many of us have are so massive that it gets harder to be safe. I have used Google Drive as my offsite storage, but if my own drive gets wiped and syncs then I can still lose it all. I ought to get a big USB drive to take a copy every so often. There are more critical files that might fit on a flash drive.
I assume there must be network storage backup systems that would be resistant to mass wipes or scrambling, but that may not be viable for personal use. I need to look into this more.
Thanks for reminding me.
