You are most likely correct in your position. If the database were = corrupt to the degree that the agent couldn't back it up, it is very = likely that you would have a bunch of users complaining as well. I = would turn up the database logging and then watch the application event = log for a day or two, that may give you additional insight. I've not = used your particular backup software for doing an exchange backup, but = all the agents that I've seen don't actually talk to the files = themselves, they talk to a set of Exchange APIs that are responsible for = the facilitating the backups. When a backup begins, you should see this = in the application even log that Exchange is beginning a backup. You = should have two different type of backups on the Exchange server. One = (the agent) only backs up the Exchange databases, the other (the file = level) backs up all the other files, but not the databases. Let me know = if additional clarification is needed.

I know we are doing a an on-line backup. That's why we purchased teh exchange agent because we are never allowed to take down e-mail except = for maintenance. My real question is if we actually have a corruped = database, nothing would work right??? -----Original Message----- From: Bryan Ard [mailto:Bryan.Ard@xxxxxxxxxxxxx] Sent: Monday, February 09, 2004 12:42 PM To: msexchange@xxxxxxxxxxxxx Subject: [msexchange] Re: Information Store Question Sounds like the "file" backup is failing because those files are locked. If you are shutting down the exchange server and doing file level =3D backups (cold-backup) then not being able to backup the files are a =3D problem. If you are using the exchange agent, you would be doing a =3D "hot-backup" of the database, i.e. backing it up while it is still =3D running. Ask your tech which approach they are performing. -----Original Message----- From: msexchange-bounce@xxxxxxxxxxxxx [mailto:msexchange-bounce@xxxxxxxxxxxxx]On Behalf Of christine easton Sent: Monday, February 09, 2004 11:23 AM To: 'msexchange@xxxxxxxxxxxxx' Subject: [msexchange] Information Store Question Hello all, I'm running Windows 2k with Exchange 5.5. We use ArcServe to backup =3D with the Exchange agent to back up our information store. My question is, Arcserve is reporting that it can not read our priv.edb and pub.edb to backup are stuff (this does not happend all the time). My backup tech states it's because our information store is corrupt. Could that be? I thought our exchange server be dead in the water? Nothing in our =3D exchange event logs and we are running fine. I think that maybe That particular backup job failed, but before I talk him about it I wanted to get other = =3D feed back.
