Runtime & Data Transfer

[iacon]

I am after some advise on how I should manage our data transfers.

We have a number of databases in the field that require data entry out on site and then a data download at the end of the day once the work is complete.

These databases work in a runtime solution.

We currently transfer data via e-mail. My issue with this is that we from time to time lose data from e-mails going missing. Because I can't network to the master system from the run time solution does anyone have a better more reliable way for me to do this?
