I have config downloads going to my servers filesystem (in addition to database). I have a Windows batch file that runs daily to dig through the filesystem looking for *.Running-Config to create a list for the day (the search gets *Running-Config from current date). That list is the basis for an automated secure copy job to another server. I have a line in the batch file that counts the number of lines in the list of configs for the day on my server filesystem. Additionally a line to put current date and time. Each day I check to see how many configs I got (and since my batch file appends the text file that represents the number of configs and current date, I compare to previous days).
Feature request from myself to myself: Add a line in batch file to do DOS fc (file compare) of 'everything' vs. what did I get a config for.
