One local one, one external one. In the external case, it's just a Nextcloud instance, constantly syncing the most important files. In the local one, there's an external hard drive connected to Raspberry and cronjobs that scp into it. So, three constant copies of everything out of any importance. I "test" the backups regularly because I'm playing files from a backup on a Raspberry connected to my sound system and constantly downloading files on my phone from Nextcloud.
