I highly recommend everyone stop using Google, including Google drive. But self-hosting "cloud" file storage is complicated for the average user, and easy to break, so I recommend using Dropbox (which for the past few years has used MS Office Online as editor for MS Office docs) and back that up on your own. Why Dropbox? It's super reliable, doesn't force its own filetypes on you (mostly), and has native clients for everything including linux cli. So this is something you can set up for your entire family, have backups go reliably and in the background, so that if something like this happens you can restore. And of course, for any sensitive files you don't want Dropbox to read, you gotta encrypt it yourself - but I'd say for the average user that encryption is only needed in rare occasions.
