User's Guide

• NEVER back up to the desktop from the standby server, because that process overwrites the
existing file in /usr/local/smx/backups.
• As the second part of synchronization, the standby server runs a restore to itself using the file found
in its own /usr/local/smx/backups directory. This should be the only file ever copied over
from the primary server.
Synchronization Rules
• You should only back up the primary server. NEVER schedule or perform a backup on the standby
server.
• Synchronization should only be done from the standby server. NEVER schedule or perform a
synchronization on the primary server.
• Always schedule or perform a backup on the primary server one hour before scheduling a
synchronization or performing an on-demand synchronization on the standby server. Backups
require more time as the primary server continues collecting configuration data.
• NEVER schedule backups at the same time as a synchronization. This will NEVER work.
• Scheduled jobs should be included when backing up an appliance before synchronization. This will
save you valuable time when restoring the backup on a new appliance. Unless you have backed up
your scheduled jobs, you will have to recreate them on the new appliance.
Manual Synchronization
Follow these steps to manually synchronize your primary and secondary ADSP appliances:
1. On the secondary server, select the Designate this as a Secondary (redundant) appliance
checkbox. The synchronization options activate.
2. Enter the IP address or DNS name of the primary server you want to synchronize with in the
Address field.
Note
If using a DNS name, it must be defined by your DNS server.
3. Enter the port number of the primary server in the Port field.
4. Enter the username in the Username field that allows you to log in on the primary server you are
synchronizing with.
Note
It is a good practice to setup an admin account (using the same username and password)
on both the primary and secondary server.
5. Enter the password in the Password field that allows you to log in on the primary server you are
synchronizing with.
6. Select whether you want to synchronize appliance name and/or synchronize mail relay.
7. Click the Sync Now button. Configuration files are downloaded to the secondary server.
