Not in itself, but you can run rdiff-backup on a system with block device encryption such as LUKS + dm-crypt, and at the time of writing this is offered as an option ('encrypt with LUKS') when installing Ubuntu Server, which makes it easy for a new machine. Ubuntu also now (v23.10) offers TPM-backed full disk encryption for those who need more extreme precautions (or are just paranoid), see https://ubuntu.com/blog/tpm-backed-full-disk-encryption-is-coming-to-ubuntu.Is encryption an option for rdiff-backup?
Or use fscrypt or a filesystem that supports encryption natively such as Bcachefs or ZFS. For some discussion of the relative merits of these approaches see https://github.com/google/fscrypt.
Or for a backup solution with bundled encryption, look at duplicity https://duplicity.us/. It uses forward diffs rather than rdiff-backup's reverse diffs, which IMO is unsatisfactory for long-term regular backups; but your use case may be different.
