I understand the usefulness and convenience of a site like backblaze, but if I wanted an offline backup and my drive is under 100gb, would it make sense to just make an encrypted full disk dmg image of my main drive every once in a while and put on something like google drive which is a couple bucks a month for 100 gigs storage?
In case local backups aren't working (unlikely) I could use another computer to grab the file onto a thumb drive, and restore the image from disk utility recovery and it should work?
Could the usb with the dmg be ntfs or exfat coming from windows, or would it have to be hfs+ or apfs for disk util to see it?

Yes, you could image and save the whole image every month, but that comes with several drawbacks:
