Back Up Your NetQ Data
NetQ 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.
If the rollback option is selected during the lifecycle management upgrade process (the default behavior), a backup is created automatically.
To manually create a backup:
If you are backing up data from NetQ 2.4.0 or earlier, or you upgraded from NetQ 2.4.0 to 2.4.1, obtain an updated backuprestore script. If you installed NetQ 2.4.1 as a fresh install, you can skip this step. Replace <version> in these commands with 2.4.1 or later release version.
cumulus@switch:~$ tar -xvzf /mnt/installables/NetQ-<version>.tgz -C /tmp/ ./netq-deploy-<version>.tgz cumulus@switch:~$ tar -xvzf /tmp/netq-deploy-<version>.tgz -C /usr/sbin/ --strip-components 1 --wildcards backuprestore/*.sh
Run the backup script to create a backup file in
/opt/<backup-directory>being sure to replace the
backup-directoryoption with the name of the directory you want to use for the backup file.
cumulus@switch:~$ ./backuprestore.sh --backup --localdir /opt/<backup-directory>
You can abbreviate the
localdiroptions of this command to
-lto 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:

Verify the backup file has been created.
cumulus@switch:~$ cd /opt/<backup-directory> cumulus@switch:~/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.
