Objective
Describe the required procedures for configuring the backup process on OpMon.
Target audience
Intended for OpMon administrators and the IT teams that need to perform backup settings on OpMon.
Solution
On IT area, after concluded an installation, configuration, activation and all is working in perfect order, one of the most important things is backup. Here we don’t forget that, and also is extremely important, because if takes place any hardware problem, we can easily recover the information.
For that there is a process that is ran on a daily basis on cron and is responsible for performing the base dump as well as the copy of the configuration files for a temporary location, in order to keep centralized all the OpMon important information for a case of “disaster & recovery”.
For knowledge, the responsible task for that is called backup, as listed below.
[root@opmon /]# ls -l /etc/cron.d/backup -rw-r--r-- 1 root root 319 Jul 7 11:38 /etc/cron.d/backup
Within this task we have the following content, where the file opmon-base.pl performs the base dump and the file opmon-conf.pl performs the compression of the configuration files.
[root@opmon /]# cat /etc/cron.d/backup # Descomente, caso backup seja do Cliente 5 0 * * * root /usr/local/opmon/utils/opmon-base.pl -E >/dev/null 2>/dev/null 5 0 * * * root /usr/local/opmon/utils/opmon-conf.pl >/dev/null 2>/dev/null
The previous routine stores the files listed below on the directory /var/tmp/opmondb, where is only required a copy of them.
[root@opmon /]# ls -l /var/tmp/opmondb/ total 202548 drwxr-xr-x 2 root root 4096 May 3 10:30 mysql drwxr-xr-x 2 root root 4096 Jul 8 00:05 nedi drwxr-xr-x 2 root root 4096 Nov 30 2010 ocsweb drwxr-xr-x 2 root root 4096 Jun 22 00:07 opcfg drwxr-xr-x 2 root root 20480 Jul 8 00:09 opmon4 -rw-r--r-- 1 root root 34316 Jul 11 00:06 opmon-conf.tar.gz drwxr-xr-x 2 root root 12288 Jul 8 00:36 opperf drwxr-xr-x 2 root root 4096 Jul 6 19:37 otrs drwxr-xr-x 2 root root 4096 Nov 30 2010 seagull drwxr-xr-x 2 root root 4096 Nov 30 2010 snmptt drwxr-xr-x 2 root root 4096 Nov 30 2010 Syslog
The advice is that these files are copied on a daily basis, the storage time corresponds with the client’s backup policy.
The copy of the files can be done in different ways, for example:
a) With a backup agent, where this agent can vary for each client according to the necessity. Keeping in mind that the agent must be compliant with Red Hat Enterprise 5 or CentOS 5.
b) With a “share”, preconfigured on OpMon, requiring the next steps for activation.
Place the process on system startup
[root@opmon opmondb]# chkconfig --level 345 smb on
Starting the process
[root@opmon samba]# service smb start Starting SMB services: [ OK ] Starting NMB services: [ OK ]
Done that, the access to backup files will be available through access to the path IP_do_OpMonopmon.
Some other options of the backup utility used:
[root@opmon /]# /usr/local/opmon/utils/opmon-base.pl
Logging on file /var/log/backup.log
Usage: /usr/local/opmon/utils/opmon-base.pl [OPTION]...
Export/Import OpMon database
General Options:
-r - Import database from /var/tmp/opmondb to mysql
-e - Export database from mysql to /var/tmp/opmondb
-R - Recover all databases from /var/tmp/opmondb to mysql
-E - Export all databases from mysql to /var/tmp/opmondb
