Importing logs on a daily basis


I now have Piwik running for a handful of sites, one of which gets about 7K visits / day - the others get less than 1K visits between them. I had quite a time importing 1 year’s worth of past logs, but that’s all done and dusted now.

None of the sites are using javascript - they all just get their logs imported daily with and after importing them all I run
archive.php with --force-all-websites --force-all-periods

Should I be using these switches when I’m running archive.php daily?

I know that if I switch any of the sites over to using javascript I need to not import its logs to avoid double counting but I will then need to run archive.php more often e.g. hourly or semi-hourly. If I do that what switches should I use?
