Rough estimate here:

If you upload 4tb in a year, that's 333.33gb/month

So for tarsnap that equals

- $1k/year in data transfer charges (4000gb * $0.25 transfer charge * 12 months)

- $83/month per month of data (333gb * $0.25 storage cost/month)

- $6.4k/year for the first year ($83 * 78 cumulative months in a year)

So $7.4k for 12 months resulting in 4tb

If usage stays the same each year will add $12k to the incremental yearly cost

I have 4TB of data, which changes an unknown amount (probably around 20-50GB per month) and grows slightly (probably 5-15GB per month).

In any case, thanks for the calculation. Tarsnap is apparently not for the common person who wants to back up everything including their media.

That actually works out worse - $14K for the first year, $13K for the second year.
