nextcloud

"It is our mission to put you back in control over your data. While not everybody can run their own Nextcloud server, hundreds of thousands of people do. Making it easier for them to keep their data safe is important. If you are one of them, Nextcloud Backup is for you!

With Nextcloud Backup, you can find a friend or family member who has their own Nextcloud server and ask them to create a user account for you. Then, you can setup Backup to regularly store compressed, encrypted backups of your data on their Nextcloud server! If something goes wrong, you can restore your Nextcloud, or even bring back individual files and folders. Of course, it might make sense to, in exchange, create an account for them on your server to store their backups!

What makes Nextcloud Backup different from other backup solutions? Its ease of use! If you are using a backup technology that you are comfortable with, keep using it. Nextcloud Backup is for those users who have found it difficult and time consuming to setup another backup solution."
