Cisco Cisco Content Security Management Appliance M160 Guia Do Utilizador

During a full initial backup, a backup of 800GB may take up to 10 hours. Daily backups, may take up to 
3 hours each. Weekly and monthly backups may take longer. These numbers may vary. 

AsyncOS 
version 

The AsyncOS version of the source and target Security Management appliances 
must be the same. If there is a version incompatibility, upgrade appliances to the 
same release before scheduling a backup. 

Target appliance 
on the network 

The target appliance must be set up on the network. 

If the target appliance is new, run the System Setup Wizard to enter the necessary 
information. For instructions, see 

Communication 
between source 
and target 
appliances 

The source and target Security Management appliances must be able to 
communicate using SSH. Therefore: 

Port 22 must be open on both appliances. By default, this port is opened when 
you run the System Setup Wizard. 

The Domain Name Server (DNS) must be able to resolve the host names of both 
appliances using both A records and PTR records. 

Target appliance 
must not be in 
service 

Only the primary appliance should pull data from managed email and web security 
appliances. To ensure this, see 

. 

Also, cancel any scheduled configuration publishing jobs on the backup appliance. 

Appliance 
capacity 

The disk space capacity of the target appliance must be the same as or greater than 
the capacity of the source appliance. Disk space allocated to each type of data 
(reporting, tracking, quarantine, etc.) on the target appliance cannot be less than the 
corresponding allocation on the source appliance. 

You can schedule a backup from a larger source to a smaller target Security 
Management appliance as long as there is enough space on the target appliance for 
all of the data being backed up, for each type of data. If the source appliance is larger 
than the target appliance, you must reduce the space allocated on the source 
appliance to match the space available on the smaller target appliance. 

To view and manage disk space allocations and capacity, see 

. 

For disk capacity of virtual appliances, see the Cisco Content Security Virtual 
Appliance Installation Guide. 

Multiple, 
concurrent, and 
chained backups 

Only one backup process can run at a time; a backup that is scheduled to run before 
a previous backup has been completed will be skipped and a warning sent. 

Data from a Security Management appliance can be backed up to a single Security 
Management appliance. 

Chained backup (a backup to a backup) is not supported.
