Cloud Backup / Nextcloud

Nextcloud is an online storage but in contrast to services like Google Drive it is intended for self hosting. You can download it freely from their website and install it on your webserver.

Remote backup

In OPNsense¹ you can backup your configuration directly and automatically to services like sftp and Nextcloud, using the backup feature.

After set-up, the backup feature will run a first backup of the OPNsense configuration file. Then, if the configuration is subsequently changed, a new backup will be run once per day early in the morning.

You may consider specifying additional Cronjobs when more frequent remote backups or remote backups at different times of the day would be required.
