Backup Your NetQ Instance

NetQ 2.x data is stored in a Cassandra database. A backup is performed by running scripts provided with the software and located in the /usr/sbin directory. When a backup is performed, a single tar file is created. The file is stored on a local drive that you specify and is named netq_master_snapshot_<timestamp>.tar.gz. Currently, only one backup file is supported, and includes the entire set of data tables. It is replaced each time a new backup is created.

To create a backup:

  1. Run the backup script to create a backup file in /opt/<backup-directory> being sure to replace the backup-directory option with the name of the directory you want to use for the backup file.

    cumulus@<netq-platform/netq-appliance>:~$ ./backuprestore.sh --backup --localdir /opt/<backup-directory>
    

    You can abbreviate the backup and localdir options of this command to -b and -l to reduce typing. If the backup directory identified does not already exist, the script creates the directory during the backup process.

    This is a sample of what you see as the script is running:

    [Fri 26 Jul 2019 02:35:36 PM UTC] - Able to find cassandra pod: cassandra-0

    [Fri 26 Jul 2019 02:35:48 PM UTC] - Backup finished successfully!
    
  2. Verify the backup file has been created.

    cumulus@<netq-platform/netq-appliance>:~$ cd /opt/<backup-directory>
    cumulus@<netq-platform/netq-appliance>:~/opt/<backup-directory># ls
    netq_master_snapshot_2019-06-04_07_24_50_UTC.tar.gz
    

To create a scheduled backup, add ./backuprestore.sh --backup --localdir /opt/<backup-directory> to an existing cron job, or create a new one.
