The SALVIAS databases accessed through www.salvias.net have recently been archived, but are currently still available online at http://www.salvias.net/pages/index_old.html. The MYSQL databases salvias_users and salvias_plots have been compressed and stored in full in tar.gz format.
As more and more data from SALVIAS is being stored and served through BIEN, eventually the SALVIAS site may be discontinued. The backups were done to prepare for this eventuality.
This tutorial explains how to access SALVIAS data through RBien.
