We are running Piwik to track stats on high traffic sites and I’ve seen that it is possible to purge logs manually on the FAQ page : piwik.org/faq/troubleshooting/#faq_42
My question is : is it ok to purge logs every sundays for example, just after auto-archiving process? I mean, will we lost data or not?
The feature of automatically deleting old older than 7/30/N days is now available in Piwik, under Settings > Privacy > Delete old logs from the database.
