So far I've been storing my RAW files on external HDDs (3 copies, one off-site). I now have about 10 TB of photos+videos and I'm thinking of cloud as a backup for RAW files. Option 1: backup "only" in case something happens to the HDDs. so access would be very infrequent, if ever (Amazon Glacier). Option 2: backup that I could also use to access images (e.g., Amazon Cloud drive) Option 2 seems pretty expensive (compared to keeping HDDs myself and not having any cloud backup)- with amazon could drive, it would be $600/year (same with Backblaze B2). Of course, I could instead store low-res images on the cloud and fit everything in a free service- and maybe option 1 + that would be cost effective. What would you recommend? is there a cheaper option than Amazon Glacier?
