I recently ran several Windows updates on my server and rebooted. I noticed a couple days afterwards that my free space on drive C: was declining. This had happened once before and Microsoft assisted me by enabling Circular logging in for Exchange. So, I looked at that setting and it was not longer set to circular logging (maybe one of the updates reverted it?). So, I renabled circular logging for now, dismounting and remounting the Mailbox Store so it could take affect. I will readdress this later and perhaps move the logs to another drive and disable the circular logging, but for now I need the space. I then moved some old intepub log files off of the C:drive to clear more space. Currently, I am running the WSUS cleanup wizard. None of these aforementioned appear to be slowing down the free space decline.
Finally, I notice that C: drive has shadow copy enabled. Is there any advantage to having it , or disadvantage to disabling this? I use Windows Backup to backup my server once a day ( I plan to do a couple a day after this is taken care of)
It is set to be limited to 13926 Megabytes and appears to be scheduled at 7 am and 12 pm (these do not coincide with my backup time). There are copies (2 per day) going back as far as 3/25, and I had rebooted the server the weekend prior. I don't recall ever going in and setting it up one way or another.
If anyone has any suggestions based on what I have provided, or can suggest other methods or tools I can use to track down the issue I sincerely appreciate it. Especially as it is continuing to go down after all my efforts so far. Thanks
