Requirement forOnline Backup / Restore of Microsoft Exchange Server

Summary
Turbo Backup 's online backup service allows you to backup live Microsoft Exchange Server databases (i.e. while the databases are running). For more information, or to compare the benefits of online/live versus
offline backups, see Microsoft Exchange knowledge base article - Q237767.

• The machine, on which the Microsoft Exchange Server is running, must have all the default administrative shares (C$, D$, ADMIN$).

Online Backup
The account that you are using either must be a member of the administrative group, or explicitly
included in Microsoft Exchange with administrator rights.
If the online backup client is not a member of the same domain as the Microsoft Exchange server, you must enter the network credentials when creating the online backup set (Select Server Wizard Tab). In the Enter
Network Credentials dialog, you must specify either a computer name or domain name for authentication.

Microsoft Exchange server will not accept <None>, as in this case online backup client performs logon impersonation (and this is invalid, since the online backup client is not a member of the same domain).
You must also create an account on the online backup client computer, which is exactly the same (name &
password) as the Microsoft Exchange server administrator account. This way, when the online backup client
computer performs the authentication, you can select online backup client computer name in the "From"
field.
Microsoft Exchange Backups are "packages" of files that are all interdependent. If one file is missing or
corrupted, the entire backup session cannot be successfully restored. If for any reason, there is an error in the backup of the Microsoft Exchange Server, online backup client will delete all the files backed up during
that session.

Restore
If you restore only the DS database (Microsoft Exchange 5.5 only):

• You must run the ISINTEG.EXE -PATCH before you can start the information store. This will synchronize the Microsoft Exchange databases.

• Otherwise, you will get the message "The information store was restored from an offline backup. Run ISINTEG with the - PATCH option before starting the information store" in the Event Log of the machine running Microsoft Exchange.

• The Patch is normally found in the path - DRIVE:\exchsrvr\SERVER\ENG\SETUP\I386\BIN>

• You cannot restore the DS database to an alternate location.

For restores of Microsoft Exchange 2000:

If, during restore, you receive the error "The server is not operational", make sure the online backup client computer can resolve the fully qualified domain name of the Exchange computer through a proper DNS setting.
In cases where you are performing disaster recovery drills, or an actual disaster recovery, several checks must be performed:

1. Assuming the machine that you backed up no longer exists (i.e. was destroyed), you must configure a new machine and install Microsoft Exchange on it. If you had a backup set for the entire machine (including registry), you can restore immediately. Otherwise, follow the next step;

2. If you did not restore the registry, check the following:

• Make sure that the machine names are the same (the server that you are restoring to must have the same name as the server that you backed up).

• The same applies for the domain name and the administrator account.

• Make sure the location of the databases is the same (including the drive letters).

• Once you have all these checks performed, you can start the restore process. After the restore is complete, you should have no errors, and Microsoft Exchange should be up and running.
