Can you lower that to something smaller? Ten seems like a lot of log files. I'm not sure what are in the log files, but rotating them once a week and keeping ten of them means that you have ten weeks worth of those logs. I suspect that is way more than necessary? I would guess that not more than a week's worth of logs is going to be useful, if even that.

What is in these logs anyways? I'm going to guess that there isn't any identifying ip addresses or similar, but what might be there that is useful to keep around?
