Lochness is a data management tool designed to periodically poll and download data from various data archives into a local directory. This is often referred to as building a "data lake" (hence the name).
Out of the box there is support for pulling data down from Beiwe, XNAT, REDCap, Dropbox, external hard drives, and more. Extending Lochness to support new services is also a fairly simple process.
Just use pip
pip install lochness
