The SSH Connections and SSH Keypairs widgets on the Backup Credentials screen display a list of SSH connections and key pairs configured on the system. Using these widgets, users can establish Secure Socket Shell (SSH) connections.

You must also configure and activate the SSH Service to allow SSH access.

These SSH credentials are used to manage SSH connections specifically for automated tasks such as replication, backups, cloud sync, or other system-to-system operations. You can generate, store, and manage SSH key pairs and define SSH connections that TrueNAS uses for these automated processes. The key pairs managed here are not tied to individual user logins, but are instead used by the system for secure communication with other systems or services.

Rsync provides fast incremental data transfer to synchronize files between a TrueNAS host and a remote system. The Push function copies data from TrueNAS to a remote system. The Pull function copies data from a remote system to the TrueNAS local host system and stores it in the dataset defined in the Path field.

There are two ways to connect to a remote system and run an rsync task:

The Rsync Task widget on the Data Protection screen shows rsync tasks configured on the TrueNAS system. It provides access to configuration screens to add single-time or scheduled recurring transfers between TrueNAS and an rsync backup server. Rsync tasks are an effective method to back up data to a remote location.

The Rsync Tasks widget shows a description about rsync tasks until the first task is configured, then it shows a list of tasks configured on the system, with th details about the task, and the task status.
