I use a 7TB Seagate to do several system full saves, including my work VM, then air gap it.

A smaller drive that stays online for Windows File History.

All important stuff INCLUDING all pics and vids are in a OneDrive folder that is sync'd and versioned in OneDrive cloud.

OneDrive is $99/year for 6 1TB user accounts (can be nested) and comes with all the O365 programs. My wife's laptop OneDrive "documents" folder is nested in my local OneDrive so if I need to scan something, etc. she has it on her computer. No brainer.

All our devices have OneDrive so I don't have to worry any more than occasionally making sure they are syncing on stuff I don't see every day. as much as many hate on MS, I've found OneDrive to be the best and simplest solution.

Work laptop host OS gets backed up occasionally but I really don't care. If the SSD craps out, they'll send me a new one with the corp image and I'll restore my latest VM backup and all my "local" changed project files are versioned to my server in the OneDrive folder and are in the cloud as well.
