I have recently run into a situation where my Exchange 2000 Server has been taking a REALLY long time to back up. And the weirdest part is that the Information Store (which is 35+ gigs) takes only about an hour or two. The part that takes a really long time is the C:, which only has 3+ gigs of daily change. But it takes about 6+ hours to back it up. When I analyzed the drive with the Windows defragment tool I found something I have never seen before. Almost the whole drive was lit up red (or fragmented). So, after all that my question is, can I run Windows Defragment tool on a Windows 2000 Server running Exchange 2000 Server w/ a 3-drive RAID5 setup? If not, what can I use to defragment this? Any help in this matter would be greatly appreciated.
