NCP Backups and Snapshots question

HW: odroidHC1
NCP: 22.2.2
|NextCloudPi version|v1.46.7|
|NextCloudPi image|NextCloudPi_01-01-22|
|OS|Armbian 21.08.6 Buster \l . 5.4.160-odroidxu4 (armv7l)|

on the NCPanel (:4443) there’s a “Backups and Snapshots” button
Nextcloud Backups and Snapshots

however, no backups or snapshots are found even though, backups and snapshots are configured and existant

Any idea where these backups/snapshots must be located for this button to work?
(in my case, NC DATA is on a mounted SATA HDD / snapshots as well – backups are on mount NFS)
