The yearly price to store 45 GB in Backblaze B2 is $2.10.
After 12 years, your cost of storage-at-rest would total to $25.20.
Then, it would cost you $0.44 to download all 45 GB on the same day.
For $25.64 total (over 12 years), they store your data with significantly more redundancy than you when you put one copy of your dataset on one hard drive.
I chose B2 in this example because they're cheaper than blob storage from the main clouds, you're unlikely to get banned for an unrelated reason (cf. Google), and their pricing model is simple to understand.
Assuming ~120 MiB per compressed CD album, and ignoring the futzing about SI and Binary units, you can store at least 8 CDs worth of ~192 kbps music (~1 GB) in B2 for $0.005/month, and since the first 10 GB/month is free, your first 80 albums are stored for free. Then, each additional group of 8 albums is another $0.06/year.
If you're still unconvinced, and prefer the particular characteristics of control, convenience, and no direct monetary opex costs that personal self-managed storage affords, then consider that for an extra $25.64 over 12 years ($2.10 for storage-at-rest, yearly), you can have another copy of your 45 GB in the cloud, which significantly reduces the likelihood that your dataset is damaged.
You can even think of it as insurance, but with the extremely desirable property that you get your actual data back, and not just some other kind of compensation.
I generate photos and videos for one of my businesses and was backing up my laptop and external drives (connected regularly) to Backblaze. Or so I thought. When my critical 4TB external failed, I discovered that Backblaze hadn't had my system backed up for almost a year - there was a multi-TB backlog and at the throttled speed I had set for the sake of the office network, it would take 10+ years to catch up. Just something for everyone to stay aware of with cloud storage.
I currently back up to two drives at ingest, one being a per-year drive (e.g., 2020 jobs source media) that is rarely accessed. For major projects, I factor in one or two 1-2TB drives that receive an extra copy of source media and then are stashed. Not perfect, but so far so good.
