Exercise 1
Creating an Online Backup of Metadirectory Server Data
In this exercise, you will use the VIABackup utility that is included with the product to create a
backup copy of your directory data.
Scenario
You want to run an online backup of your MMS Server data.

Tasks Detailed Steps
1.
Log on to Windows 2000.
a.
Log on to Windows 2000 as Administrator with a password of
password.
2.
While the MMS Server is
running, perform an online
backup of the MMS Server
database to the
c:\mmsbackup folder.
a.
At a command prompt, type cd \zoomserv\bin and then press ENTER.
b.
Type viabackup -? and then press ENTER to display its usage
statement.
c.
Type viabackup –path c:\mmsbackup and then press ENTER to
perform the backup.
The command window displays the files that are being backed up.

Note: VIABackup is designed to lock the MMS database correctly and suspend all writes to it, thereby
giving you a reliable back up. Use another backup means to archive the \mmsbackup folder.
3.
Verify that the backup is
incremental by performing
the back up a second time to
the same folder.

a.
Type viabackup –path c:\mmsbackup and then press ENTER to
perform the backup.
The command window displays that the files are not being backed
up due to an identical size and timestamp to the existing files in the
mmsbackup folder.
How can the backup process be automated so you do not have to run viabackup manually?

Schedule it by using the MMS Scheduler or the Microsoft Windows 2000 Scheduler.

Exercise 2
Verifying Directory Integrity With the MMS Compaction Utility
In this exercise, you will run the MMS compaction utility to compress the database and ensure the
integrity of your data. After the process is complete, you will confirm that the compaction was

Exercise 3
Restoring from a Backup
In this exercise, you will simulate a failure by renaming x500.db and then restoring the file from the
backup copy you made in Exercise 1.
Scenario
A power outage and lack of an uninterruptible power supply (UPS) have resulted in an inconsistent

and non-functional directory. You will need to restore the MMS database from a backup.
