Because of this, you have to take Exchange offline in order for a defrag to be effective. The Disk Defragmentor program which comes with Winders requires that the files to be defraged are not currently open by another process. This is simply a stroke of luck and is not the doing of Eseutil.)
DISKKEEPER RUN DEFRAG FREE
If the target disk happens to have enough contiguous free space, and the newly written database happens to be written into that contiguous free space then the resulting, defragged database will also be a contiguous file. (Note: Eseutil actually writes out a new file containing the defragmented contents. That is what disk defragmenters are for, and they are definately needed with Exchange Server. It does NOT defragment the FILES that the databases are stored in. Yes, Eseutil is used to defragment the CONTENTS of the Exchange databases. diskeeper has nothing to do with exchange defragmentation." Mike C said: "use the eseutil tool to defragment exchange databases. The only questions do you want to use a Hugo or Porsche? Bottom line defrag exchange just like all your NTFS Drives. Keep in mind that to a defrag utility the database is simply another fragmented file on the disk. Because more disk reads are necessary when backing up a heavily fragmented file system, make sure that your disks are recently defragmented. Defragmenting your hard disks helps increase disk performance and helps ensure that your servers that run Exchange run smoothly and efficiently.īecause severe disk fragmentation can cause performance problems, run a disk defragmentation program (such as Disk Defragmenter) on a regular basis or when server performance levels fall below normal. The first two paragraphs pretty much provide the answerĮxcerpt from: Defragmenting Exchange 2000 Server and Exchange Server 2003 Databasesĭisk defragmentation involves rearranging data on a server's hard disks to make the files more contiguous for more efficient reads.

Google “Defragmenting Exchange”, the first hit you see is. I want to start my response by clearly stating that I am employed by Diskeeper so there is no question later about the response.ĭiskeeper says yes defrag you exchange database and you would expect that but more importantly Microsoft says yes and in writing. So let’s stop arguing and get our facts straight!!!! If you want space back (event 1221) use eseutil. The database itself may become fragmented, but the nightly online maintenance deals with this, and no user action is required. Having said all that, if you build your exchange server properly, with database on one disk and logs on another, and if you have backups flushing applied logs once a week or so, your Exchange data will never become fragmented. A slimmed down version of this product is what’s actually built into windows!

So good in, fact, Microsoft licensed it and renamed it to the windows disk defragmenter! Yes, that’s right. If your server has files throughout that are fragmented, regardless of the type, email, web, file, etc, you should defragment it. That’s great.Įseutil defragments the Exchange database, which cannot be defragmented by Diskeeper in any way. The amount of times I discuss this isn’t as often as it used to be, but is always fun!
