How do I back up exchange priv1.edb/stm files with Arcserve Brightstor ver.11?

We are currently using Arcserve Brightstor to back up our data. I found out recently that it is not backing up the priv1.edb and priv1.stm files on the Exchange 2003 server. I verified that the Exchange Agent is installed, however, it is still not backing up those file. I am more familiar with Veritas but not with Arcserve so I'm not sure where to start to look. I have gone through CA's website but haven't had much luck. Any help or suggestions is really appreciated. Thanks.

You should be able to backup the Information Stores from the selections list. You dont need to backup the database files separately.

But what about restoring individual mailboxes? I usually use Ontrack to do mailbox restores. However, Ontrack searches for the edb files to do the extraction.
You cant backup the database files without dismounting the stores.

Can you not do a bricklevel backup in your version of Arcserv? This will allow for the restore on individual mailboxes.

If you backup the Information store you could use a recovery storage group to recover mailboxes? You should be backing up the information store anyway to truncate your exchange logs (Unless you have circular logging enabled).

Have a look at this document for Exchange Backups.

Thanks for the link Jim. I will go over it. I am not familiar with how Arcserve does a bricklevel backup. I will have to look into it. My main concern was why it was skipping the edb/stm files during backup even though it was selected. My main goal is to be able restore backed up edb files to a separate location, use Ontrack to extract individual mailboxes from the restored edb file, and save those extracted mailboxes into a pst file. I am just not sure how that is done with Arcserve. With Veritas, I was able to back up the information store and the edb/stm files. Will arcserve allow me to restore an individual's mailbox from a backup and restore it or save it to a pst file rather than restoring it to the information store?
Arcserv as will BackupExec not be able to backup the .edb and .stm files because they are inuse in the system, maybe you had the open file agent for backup exec?

You need to dismount the exchange stores to be able to free these files up for backup. So you could run a task which dismounts and mounts the store each night/morning but this would be a REALLY bad procedure for your environment!!!

Yes Arcserv will let you do a bricklevel backup, then you can restore individual mailboxes.
Your two options for recovering a users mailbox are:
1) Bricklevel backup, this is much slower than a Information Store backup, and does not truncate the exchange logs.
2)Information Store backup. Then you can restore to a recovery storage group, or a recovery server.

If you have a big enough backup device i would suggest backing up both ways.
There is no good time to bring down Exchange to backup the raw files. Exchange is designed to run 24/7. During the night it is looking after itself.

As already indicated, the preferred method for backups is the full information store, then a restore of mailboxes through the RSG. Brick Level Backups are slow, inefficient and close to useless for most data recovery scenarios.

Backupexec vers. 11 was able to backup the edb/stm files and the information store with just the exchange agent installed on the exchange server. We didn't have open file agents installed on it. I'm guessing that I need the open file agent for arcserve to be able to back up those edb files. With that said, will the RSG restore method allow me to restore the information store to a different machine then point it to that location to do a mailbox restore? As I understand it, with RSG, it restores the entire information store. We don't have enough space to restore the information store on the same server so it will have to be restored on a different server or nas box with space.That was the beauty of backup exec being able to backup up the edb files. For instance, If I had to go back to January tape backups, all I had to do was restore the edb file from the January tape to a directory anywhere on our network,  then use Ontrack to extract a certain users mailbox and save it to a pst file. Will RSG allow me to save a mailbox to a pst file rather than merging or copying it to an existing mailbox?

Thanks for all the info guys. The links provided some good info on how to backup/restore mailboxes utilizing MS Exchanges features. Does any Arcserve guru's know how to actually back up those edb files? Or do I absolutely need the open file agents to accomplish this?
You don't use an open file agent
You don't backup the files themselves.

You use an Exchange agent and then backup the store.
When it comes to recovery you follow the same procedure as with the Microsoft products except restore with your own product. Exchange then doe the rest as it is using standard Backup APIs.

I cannot tell you how Arcserve is doing it as I don't trust CA products to do their job other than acting as a tea coaster.

Okay, I"m giving up on the idea of trying to back up the edb files by themselves with Arcserve because it doesn't look it can do it. Since we have been backing up the information store, I tried to do a restore of the store to a different server, but been getting an E3022 error - No Valid Destination. I checked all the settings/permissions and all seem correct. My question is, if I restore the information store to a different destination (in this case a different server), do I need to install Exchange on that machine too? I can't do a restore on the existing exchange box because of space limitations.

Simon, Arcserve has to be the worst backup software I have ever worked with!
An information store restore has to go in to Exchange. Therefore if you want to restore to another server it needs to be an Exchange server, preferably at the same service pack status.

Thats what I was afraid of. This is the one reason why I feel its a benefit to be able to back up the edb files by themselves without having to back up the information store. You can restore the edb files anywhere without having to be on an exchange server.
What would be the point of recovering the edb files? You cannot do anything with them, as you need an Exchange server to extract the content. If you are using a third party tool to restore the data such as OnTrack Power Controls then it should be able extract from the backup files on the tape or whatever.

The only way to backup the raw files is to stop the server - but Exchange is not designed to be stopped.
