Backup CS-MARS

hi netpros,

played around with the backup on cs mars appliance.

I was wondering about two things:

- files are not in gzip format as mentioned in the docs. ok, i just started the backup, so maybe tomorrow the old data will be gzip format.

- directory structure differs from documentation:

on page 6-20 in the "Install and Setup Guide for Cisco Security Monitoring, Analysis, and Response System" a directory "ES" is mentioned but my filesystem looks like this:

mgmt-m04:~# l /opt/cs-mars-backup/

any idea if it is possible to just restore the config of the mars appliance without old incidents? (CF for config, IN for incidents?)

is there more documentation about the mars backup/restore system available?

best regards



Re: Backup CS-MARS

According to what I have been told it is not possible to restore the config of the MARS appliance minus the old incidents. In fact, you cannot delete incidents at all because it would corrupt the SQL database. Once a rule is created it can only be deactivated and can never be deleted. You would have to erase the MARS appliance completely and rebuild it to have old events removed.

The only documentation regarding backups is that I am aware of is on CCO.

Hope this helps answer your question.

Re: Backup CS-MARS

Using the pnrestore command, you can restore three types of data:

• CS-MARS OS—Restores the operating system (OS), including any upgrades that applied before the

most recent archive was performed.

• System configuration data—Restores system configuration data, such as network settings, reporting

devices, custom inspection rules, event types, reports, administrative accounts, archival settings, and

any other data that you have entered. It does not include any event data.

• Dynamic data—Restores real event data that came from reporting devices, including incidents

generated from events and cases. Performing a restore of just the configuration data results in

incomplete data required to reconstruct existing cases: all open cases reference incidents and

sessions. If this dynamic data is not restored, the cases will reference invalid incident and session

IDs. To restore cases, perform a full restore (mode 2).

To restore archived appliance data, use the pnrestore command:

pnrestore -p archive_data_nfs_path [-t start_time -m restoring_mode]


Install and Setup Guide for Cisco Security Monitoring, Analysis, and Response System


Appendix A Command Reference


Syntax Description none The default behavior of this command displays the command’s usage guidelines.

-h Displays the detailed command’s usage guidelines.

-t Restores the data dated from this time. Use mm/dd/yy:hh format.

-p Name of the directory where the archived data is stored. You must identify the NFS

server by IP address, separated by a :/ and then the pathname


-m Restoring mode. Two modes are available: 1 (default) or 2. The mode determines what

type of data is restored. Table A-2 identifies what data is restored for each option.

Examples You can use the restore feature to complete different restoring tasks, such as:

• Perform a complete restore on the same CS-MARS Appliance using the archived data (including the

OS and all data). Use the pnrestore command, mode 2. For example, in the CLI menu of the

appliance, enter:

pnrestore -m 2 -p

• Archive and restore data to a different CS-MARS Appliance of the same model. From the appliance

where you want to archive the data, use the GUI to configure archiving. From the second appliance

to which you want to copy the archived data, use the pnrestore command.

For example, if you only want to copy the OS and the system configuration data, you should use

mode 1 of the restore command. For example in the CLI menu of the new appliance, enter:

pnrestore -m 1 -p NFSSeverIPOfOldBox:/archive/CS_MARS1

maybe i should just rtfm
