Chapter 14 Administering the CAM
Backing Up the CAM Database
Step 2 If you need to upload the snapshot image from an external machine first, click the Browse button next
to the Snapshot to Upload field, find the file in the external directory structure, and click Upload
Snapshot.
Step 3 Log into the CAM CLI console and shut down services on the CAM using the service perfigo stop
command.
Step 4 Enter the /perfigo/dbscripts/dbbackup.sh command. The existing configuration is overridden by the
configuration in the snapshot.
Warning Entering the “./dbbackup.sh” command using “sh ./dbbackup.sh”syntax can cause the backup
process to enter an endless loop, repeatedly asking you to verify the restoration process. Do not use
the “sh ./dbbackup.sh”syntax.
Step 5 Restart services on the CAM using the service perfigo start command.
Restoring a CAM Snapshot—HA-CAM or HA-CAS
Note The CAM snapshot contains all database configuration data for the Clean Access Manager and
configuration information for all Clean Access Servers added to the CAM's domain.
If either of the HA-Primary and HA-Secondary CAMs and/or CASs in your HA deployment lose their
configuration, you can retrieve the most recent snapshot (or create one for the existing configuration)
from the remaining CAM and load it into your HA system to ensure consistent behavior from both the
HA-Primary and HA-Secondary machines.
If both the HA-Primary and HA-Secondary CAMs and or CASs in your HA deployment lose their
configuration, you can restore the system using the following guidelines. (For example, if a catastrophic
event wipes out the image and database on both the HA-Primary and HA-Secondary machines or forces
you to RMA both machines and install new appliances.)
Warning Do not attempt to restore a snapshot on either the active or standby CAM if the standby machine is
offline (down or still rebooting).
Restore Both HA-Primary and HA-Secondary CAMs from Snapshot
To restore the HA-Primary and HA-Secondary CAMs in a failover deployment to the configuration state
of the snapshot:
Step 1 Install and initially configure the HA-Primary CAM and HA-Secondary CAM so that they feature the
same attributes as before your HA deployment went down as described in the Cisco NAC Appliance
Hardware Installation Guide, Release 4.9(x).
Step 2 Apply your CAM user license(s) to both the HA-Primary and HA-Secondary CAMs.
Step 3 Reconfigure the HA-Primary and HA-Secondary CAMs as an HA pair as described in the Cisco NAC
Appliance Hardware Installation Guide, Release 4.9(x).
Step 4 Shut down the HA-Secondary CAM to prevent it from automatically assuming the “active” role during
database restoration.
