If your device is having CLI and proper CLI command to retrieve the backup(probably a text config), then we can make CatTools to automate your backup jobs on that device.
I know this is an old post... but I just came across it on Google and thought I may as well post the answer - or at least the part of the answer that relates to loadbalancer.org
From the loadbalancer.org CLI you can run:
lbcli --action support-download
A successful output will display where the backup is located i.e.:
CLI: generate support archive completed.
The archive can be found in: /var/www/html/tmp/
Don't hesitate to ask email@example.com for any questions like this.
