If the problem is large web logs, why not try using cronolog 
(http://www.cronolog.org).

This is a utility which will create daily logs straight from apache.  
For example here is an extract of my httpd.conf (may wrap - should be 
two lines in the vhost section):

<VirtualHost xxx.xxx.xxx.xxx>
LogFormat "%v %h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-
Agent}i\"" combined
CustomLog "|/usr/local/sbin/cronolog 
/home/sites/site1/logs/%Y%m%daccess.log" combined
</VirtualHost>

This basically pipes the log data from apache to cronolog, which 
looks at the name of the log file specified ( %Y%m%daccess.log ) and 
replaces %Y with the year, %m with month etc. 

Cronolog automatically changes the log file name at midnight - 
meaning you can remove apache logs from the split_logs process.
