if that’s an option, be sure to backup your raw data, also consider backing up your database see https://github.com/nextcloud-snap/nextcloud-snap/wiki/Export-and-Import
Depending on the type of failure you’ve experienced, there is a good chance of recovering your data. By default all the stuff you care about is in the /var/snap/nextcloud directory. So just copy the entire directory to another drive or machine. In the worst case you could lose your database, but at least you’ll preserve your raw data. Your data can be found in /var/snap/nextcloud/common/nextcloud/data if you haven’t changed your data directory. See where is my stuff.
