I am looking for some best practices on Archiving and its relationship with long

I am looking for some best practices on Archiving and its relationship with long term reporting. We have some processes that we need to report on for a couple of years. Though Appian allows to configure the archival setting to '999' what is ideal? What makes a process heavy - obviously data and the number of sub- processes would count - but is there a best practice defining no of sub process/parameter limits for this? I am just trying to quantify and figure out which processes need to be curtailed to free my cache. Once I have a defined mechanism to figure out the 'heavy' processes I can use the "Send Message" event from the "END" event of my process and send ONLY the fields needed for my reporting to a reporting process. Please advise....
