My exchange server has recently just started loosing freespace. Most days I have 25GB of free space on my Exchange Server yesterday I had 8GB today I have 4GB. I used a program called TreeSize and it says I am using 42GB of my 67GB partition. My exchagne is setup to use upto 25GB. The last time this happened I had to reboot the server and run scan disk, that took a long time to run. I also noticed when I analyzed the drive for a defragment that there was a System Volume file wht 4,400 fragments that was about 12.79Gb in size. Is there a way to free this space up without rebooting and doing a scan disk?

I have attached the Analysis Report from Disk Defragmenter.

i am familiar with treesize, i use it myself...the idea of treesize is that it tells you how much data is being used in a folder and you can go down every level till you cant go now no more..just find what it is that is using the most amount..

The problem is treesize is not finding anything that is using the space. according to treesize I am using 42GB but windows says I am using 63GB. The last time I had this problem I ran scan disk and it repaired the problem, but I would prefer not to do that because 120+ people at my orginization get frantic if they dont have email for 3 hours.

yeah that is a problem...are you not able to do this overnight?

have you noticed any changes in your backups? an increase in time taken? or amount backed up?

When did you last to a "normal" exchange backup - that will truncate the transaction logs.

I am not sure if it will have enough freespace by tonight at the rate its looksing. I have Veritas 9.1 installed on my main file server and it also backs up my exchange server I have the Exchange modlue for it. Usually when I do that it free up log space.

honestly then unless you can find what is suddenly taking up all that space..you will have to do a scan disk...if any one complains then think of it this way..3 hours downtime on email is better than 3 days because your Ex Server overloade and then you cant get any emails back then..

try to run a windows backup of the exchnage database & fi you dint have space on the server , save it on a network drive .
Some time the varitas backup does not turncate the logs
If the problem is the disk then you should look at moving the server or rebuilding the server using new  disks

I have freed up the space. Apparently Shadow Copy went wacky or something. Since the defragment log was showing a large amount of space in the System Volume Information folder I thought I would look at the Shadow Copies tab on the C: Drive. It apparently was using somewhere arount 22GB I tried to enable the disable Shadow Copies and it told me it could not delete because of a running backup. There are no running backups that I can find but I did limit the amount of space Shadow Copy can use on the drive to 2GB and it freed up alot of space. No I need to figure out why it thinks there is a backup running. I even killed the beremote.exe process, which is part of Veritas Backup Exec.

Nothing was under scheduled tasks. My best guess is that since I did not have a tape in the drive last night and the backup timed out, it may not have notified the exchange server and so it was still trying to shadow copy continiously.
