How to create a Local Mirror of http://step.esa.int/auxdata/dem/SRTMGL1/

Hello,

I am just wondering the best way to create a local mirror of the DEMs to run S1TBX without requiring aux data download on demand. Also, how to do this without overloading the server resulting in an IP block. Use a wget mirror command such as

wget --recursive --page-requisites --adjust-extension --span-hosts --convert-links --domains http://step.esa.int/auxdata/dem/SRTMGL1/ --no-parent http://step.esa.int/auxdata/dem/SRTMGL1/
?

I am just trying to figure out the best way to get the needed auxiliary data locally to avoid needing to send requests to get it downloaded on demand, as I have learned sending to many requests while processing (docker cluster processing) results in gpt not working due to the IP block.

Thanks
