Rest-Server
Auf dem Rest-Server liegen die Daten in dem angegebenen Verzeichnis --path /home/rock64/backup
root@rockpro64:/# ls -lha /home/rock64/backup/
total 32K

User Authentifizierung
Zur Benutzerauthentifizierung benutzt der Rest-Server das Tool htpasswd, dazu muss folgendes installiert sein.
apt install apache2-utils
Danach kann man im Backup Pfad die .htaccess anlegen.
root@rockpro64:/home/rock64/backup# htpasswd -B -c .htpasswd frank
New password:
Re-type new password:
Adding password for user frank
Sieht dann im Verzeichnis so aus.
root@rockpro64:/home/rock64/backup# ls -lha
total 36K
drwxr-xr-x 7 root root 4.0K May 10 10:16 .
drwxr-xr-x 5 rock64 rock64 4.0K May 10 09:43 ..
-rw-r--r-- 1 root root 67 May 10 10:17 .htpasswd

Man kann jetzt, auf dieses Verzeichnis, nur noch drauf zugreifen wenn man sich mit USER und PASSWORD authentifiziert.
