There are some third parties online estimator on internet, but in your case, the calculus should not be too hard.
In the following page, you have all the fees for all the cases: https://aws.amazon.com/fr/s3/pricing/ Basically, there are only 2 kind of fees that will be charged to you for this operation: 1) (GET,LIST, ....) fee required for the requests needed to do the operation 2) A data transfer out fee that is dependent of the size of the object that you want to download. For 1), you can just ignore it is it will probably be insignificant. You just download a single file, so the overall operation will just requires a dozen of requests. You pay proportionally to your usage with something like 0.005 or 0.0004 per thousand of request. So we can easily assume that you will probably be charged a lot less than 0.0005. For 2), this is where the cost will be significant. Here, I guess that you will transfer to "Internet" (ie you download to your computer). (Other case are transfer/copy bucket to bucket) For this it is a price per GB, with different levels. So, if we take the example of the 100 GB file: You will pay 0$ for the 1st GB +0.09 * 99 = 8.91$ for the remaining 99 GB. You can get the size of the file by using the "info" command instead of "get". A last point to take care of, prices are not the same depending of the "Region" where is located the file. In the amazon page, there is a select box to select the region to see the correct price. If you can't get the region info from the source, you can do 2 things: - Do your estimate with the most expensive region that is probable for your case, and so you know the upper bound of the cost. - When you call the "info" request, use the -d flag. It will show all the debug logs of s3cmd, and you should be able to see in the first exchange in which region is the file located, as we have to redirect the requests to the correct region. As a complement, you can find another example of calculating costs in the readme of s3cmd: https://github.com/s3tools/s3cmd/blob/master/README.md (Just look at the idea, but refer to amazon page for the actual pricing) Let me know if it is not clear enough, Regards, Florent On Wed, Apr 29, 2020 at 10:58 PM Andrew Davidson via S3tools-general < s3tools-general@lists.sourceforge.net> wrote: > I need to estimate how the following transfer will cost.
