Our measurement for space of log data: (because there was a question for it) server traffic (mean): 2.000 KB/s log data for one week: 200 GByte after remove of some useless strings: 120 GByte compressed and encrypted: 20 GByte for 26 weeks: approx. 500 GByte This is very much for our server. But we hope, we do not have to log.
