Sorry, I misread your question. I thought you meant a reset of the firewall.

Netflow data will age naturally. If your firewall has insufficient disk space for the working set, you can disable local logging and do all your analysis on a remote server. Or you could, you know, add more disk space ;-)

You should use an external Netflow collector, the local one is not for big data, only to give you an insight whats going on right now.
