Love this question - been through a few iterations. For context I'm an amateur photographer (portrait) so I have a lot of RAW files that I tend to keep (almost 3TB now since 2010) from my various Nikon cameras (D90 and D7100 - not amazing but they do the job!)

I have a primary SSD for my OS and applications, a secondary SSD where I store my latest/active Lightroom catalogues/files and a large 4TB (spinning disc) hard drive for local backup.

After a shoot I'll import the files onto my secondary SSD and then manually copy them over to the local HDD once I've done my picks and culled things a bit. That HDD is automatically backed up to Backblaze so there's always an original copy of the files either local or in the cloud. Any images that I edit/pick/export will be manually uploaded to Google Photos (usually in it's own album) and I try to annually pull down files from Google to go into another 'jpg/exported' folder on my HDD that's backed up to Backblaze. My wife and I also have our iPhones backing up to Google photos automatically plus we have Apple storage/backups - so we tend to have double coverage on most things.

Some of it is a bit overkill probably but I'm particular about having access to all my photos and I've definitely gone back to look at and edit old photos/shoots so it's worked out ok for me so far.
