# Round trip of NG Backup against real S3 (s3mock) and SFTP backends, through files_external's own
# backend/auth classes, same as a production location would use. Backend correctness does not
# depend on the Nextcloud version or database, so this runs once (not matrixed across NC/DB),
# on a recent Nextcloud with sqlite. Each backend gets its own fresh Nextcloud container, since
# NG Backup's key can only be initialised once per instance.
# Usage: tests/integration/targets-matrix.sh [nextcloud-version]
