Exchange Server 5.5 Maintenance

By blkjoe_1999 ·
I have recently run into an issue with my director. It seems as though he is under the impression that running the ESEUTIL on exchange is considered maintenance. I have tried to convince him otherwise but it seems as though the former Network Admin has got him sold on this process. I was wondering if there is an outline that would show how a maintenace of the Mail server should be done?

Here is what a Microsoft white paper titled "Best Practices for Exchange Database Management" says about offline defrag:

"Online defragmentation does everything you need except shrink the size of the database files on disk. If you make major changes to your computer running Exchange (for example, if you move or delete a large number of mailboxes or remove a large number of newsgroups), you may consider performing an offline defrag by running Eseutil /d. However, in most cases, you should avoid running offline defrag because it?s an expensive operation."

The reason they say it's an expensive operation is that if you have a large database, it can take a long time (during which Exchange is offline, of course), and (2) you have to have enough free disk space available - at least equal to the size of your database. I think the decision to do or not to do offline defrags depends entirely upon the size of your database, the available storage in your system, and personal preference. One MS tech I asked about this one time said to me "If the amount of free space left after online defragmentation is more than 10% of the total size of your database, you should do an offline defrag." This is the rule I follow myself - I end up doingan offline defrag about once every 6 months. The Exchange DBs I manage are generally between 2 and 4 GB and it takes about 1 to 1 1/2 hours to defrag them. The firms I work with find this amount of down time every 5-6 months acceptable. Hope thishelps!

PS - I guess I should add that running an offline defrag is the ONLY regular ESEUTIL maintenance task that you might want to perform. I'm assuming this is what your manager is talking about. . .the other uses of ESEUTIL are recommended strictly forchecking and repairing a damaged DB. The only other practices and/or maintenance tasks that MS recommends in this white paper are NOT to use circular logging, to use high-quality hardware and maintain it properly, to always load the latest service packs, and to do regular on-line backups and testing of the backup/restore process.
