You are asking more than one quesiont here.

1. You only need to back up three files. These are the priv.edb and pub.edb file found in \exchsrvr\mdbdata. The other file you need to back up is dir.edb found in \exchsrvr\dsadata.

In order to back them up you can use the NT backup software to your local tape. Or you can get a third party software from Seagate or Computer Associates, etc. and back the files. Another alternative is to back them up by copying to another disk (removable or fixed.)

When backing then up without special software that understands excahnge you will need to stop the attendant.

When restoring the files you will need to run eseutil and isinteg against these three files. If you don't you may corrupt the store.

In restoring the files, first delete all of the files out of \exchsrvr\mdbdata. Then copy the two files priv and pub into it. After that you will want to run the eseutil and isinteg routines.

You should go to, register if you have not, and look in the knowledge base for papers on these routines. You may want to look at the following white pages: Q190696, Q149238, Q151789, Q188650, Q184205, Q192333.

As a warning: when using eseutil DO NOT USE TWO OR MORE OPTIONS AT THE SAME TIME. This will destroy your data and make it un-recoverable.

Another warning: COPY THE PRIV.EDB, PUB.EDB, and DIR.EDB before using any recovery utilities. You may even want to set up a working bench exchange server, copy the files to it, and work on them. You must use the same naming for the exhange (not the NT server) so the files will be recognized.

You may also want to get a copy of exmerge. This routine can extract information from your private and public store. You should also consider the Microsoft Exchage Server Support Utilities found on the Excahge CD.

When running these routines you want only the Attendant and the Directory services on.

This all assumes that you are not clustering, etc., but running only one exchange.

Lastly, since even with the best of backups and restore... exchange server stores are problamatic it is worth spending the $195 for a support call to MicroSoft.

2. If the store does not start, see the white papers I have enumerated above. If after using the eseutil (and having copied the files off) you can not get it to start. Delete all the files including the pub and priv in the /exchsrvr/mdbdata. Then attemt to start the exchange. It should then create a new pub and priv. You will have all of the user login and mail address information, but will lose all other store information. Then create a duplicate excahge system and copy the back up of the three files to it. Use the exmerge file to extract the damanged files and to then import them into your "fixed/empty" exchange.

Again, you should consider calling support for this.

3. Using the import/export utility is one way of backing up. If you have used it to export to PST files, you can import them after restoring the system. Then all you need to do is, stop the attendant, delete all the files in /exchsrv/mdbdata, restart the attendant (the store should then start), import the from the PST files.

4. If you have crashed already. You are in deep yogurt. All of the above is all you have. In this case... I strongly recommend you call for support and spend the $190.

Of course you are attempting to get around that dollar amount. If you have lost of time (weeks maybe) you can attempt to salvage your system with out the call.

1. I use arcserve 6.5 with the exchange module.  This allows you to backup the exchange server.

2. For the information store, have you checked the consistency of the priv.edb pub.edb and dir.edb files.  If your using exchange 5.5 use:
eseutil /mh [edb file] > output_file_name

3.  Exporting users is all well and good, but it doesnt touch the mailboxes.  They are the priv.edb files.

4.  MS have done a white paper on disaster recovery ( )
If it fails to start, then its no use backing up when it doesn't work, because when you restore it will still not work!  If the edb files show inconsistent, then use the eseutil /p option on them...
