We have recently introduced remote Borg backups for Nextcloud All-in-One instances. Before, only local backups on drives mounted directly on the server were possible. With the remote backup feature, you can specify a remote location as the target location for your backup, enhancing the reliability and security of your backups. During the system restore process, this target location can be specified to spin up a new Nextcloud AIO instance and restore the state on a new server in minutes.

Like many features in Nextcloud, the remote Borg backup feature is a community contribution. Big thanks to hannahdiels for making it possible!

In this step-by-step guide, we explore how to create a remote backup for your Nextcloud and restore your instance from one. Follow along to make sure your backup and restore go smoothly!
