Defragging Priv.edb on MS Exchange 5

By damian248 ·
What is the procedure for using the defragmentation utility, edbutil.exe on the private information store on an MS Exchange 5 server? What services do I need to stop on the server? Is this a risky and recommended procedure? My current private info store is ~1.5 GB.

First make sure you have a good backup, next take a look at these links:

One thing to look out for: there must be twice as much free space on your drive as the size of your IS, >3gb

I have Exchange 5.5 SP3 and have a new util called ESEUTIL. I haven't run it yet, but I believe you do not have to stop your services to run a defrag. Good Luck

I'm using a third party tool for defrag. It is made by Executive Associates, called Diskeeper Server Edition 5.0. I'm not sure if there is an Exchange Module. (I don't have the same issue with my Echange Server that you do)

If you are using Win2kanywhere the interface to Diskeeper will look familiar Microsoft adopted/bought the writes to use a scaled down version of it.

Presumably you want to do this because your hard drive is filling up?.
Running the utility to defrag your priv.edb is fraught with danger if your not careful.
The easy way out is to install a new large hard drive and run the exchange optimiser andmove the priv.edb to the new drive.It worked for me.

MS recommends running the offline defrag utility (edbutil.exe for Exchange 5.0) when the available free space after an online defrag (which is done automatically) is equal to or greater than 10% of the total size of your database. (To find out, look in the event log on the Exchange server for Event ID 1221 for the MSExchangeISPriv - the details of this event will show you the free space after on-line defrag.) You must have at least twice the size of your database (i.e., 3GB) free on the drivewhere you run the defrag. The recommended procedure is to stop all services, make a backup copy of the priv.edb (you can simply copy it through NT Explorer to another drive), then run the defrag. If you run into trouble, you just recopy the backupto the original location and start again. It really isn't that "dangerous" as long as you're careful about having enough drive space and having your backup copy readily available in case of problems. You MUST, however, stop ALL the services (meaning Exchange is unavail

Guess I'm too long-winded!! Exchange is unavailable while you're doing this. To defrag a 1.5 GB database (I've done one about this size) takes about an hour, depending upon the speed of your hardware.
