Exchange 2010 inetpub log files
Posted on 2014-10-09
We are running Exchange 2010 on MS Server 2008 R2. We have our EDBs on drive E:\ and our ExchangeLogs on drive F:\. Our nightly backups purge the logs and we keep both these drives with plenty of headroom. Last night, however, our Exchange server reported severe backflow issues, and I eventually realized that the C:\ drive was 98% full. This looks largely due to C:\inetpub, which is severely bloated, and doesn't seem to be getting purged by anything automatically. More worrisome is that 10 days ago, each daily log file suddenly jumped from around 70 MB to 1 GB, in one day!
1. Can someone shed some light on what these log files are and how they pertain to my Exchange server?
2. What are possible reasons for such a dramatic increase in size, as I can't recall any changes we've made in the last 10 days?
3. As a stopgap measure, to avoid my C:\ drive from filling up over night, can I manually delete old log files safely?
4. As a longterm solution, what is best practice for this directory?
