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.

Und noch zwei Dinge, die interessant sind und noch ausprobiert werden müssen
The --append-only mode allows creation of new backups but prevents deletion and modification of existing backups. This can be useful when backing up systems that have a potential of being hacked.
To prevent your users from accessing each others' repositories, you may use the --private-repos flag which grants access only when a subdirectory with the same name as the user is specified in the repository URL. For example, user "foo" using the repository URLs rest:https://foo:pass@host:8000/foo or rest:https://foo:pass@host:8000/foo/ would be granted access, but the same user using repository URLs rest:https://foo:pass@host:8000/ or rest:https://foo:pass@host:8000/foobar/ would be denied access.
Schützt Backups vor diesen fiesen Dinger, wie heißen die noch in der Windows Welt? Emotet oder so?

Rest-Server in Version v0.10.0 released. Test folgt die Tage..
Rest Server is a high performance HTTP server that implements restic's REST backend API. - Release v0.10.0 · restic/rest-server
GitHub (github.com)
Dann mal eben ausprobiert. Auf meinem Server war die Version 0.9.7 selber, mit go, gebaut. Dann mache ich das auch mit der v0.10.0 so. Aber bevor ich anfange, wird die v0.9.7 gesichert.
mv /usr/local/bin/rest-server /usr/local/bin/rest-server_0_9_7
So erspare ich mir im Problemfall das selber bauen.
Ok, dann die neue Version bauen.
git clone https://github.com/restic/rest-server.git
cd rest-server
go run build.go
Danach befindet sich im Verzeichnis die Binärdatei rest-server
Die kopieren wir jetzt
cp rest-server /usr/local/bin
Danach kurzer Test
# rest-server --version
rest-server 0.10.0 (v0.10.0-6-g037fe06) compiled with go1.11.6 on linux/amd64
Gut Version passt
Dann ein Backup gestartet. Das sichert einen Teil meines Home-Verzeichnis

So weit funktioniert das genau wie vorher. Im Changelog stand ja was von Subfoldern. Das betrifft mich nicht, weil ich für jeden User genau ein Verzeichnis habe.
So mit alles Gut Dann warte ich mal morgen ab, ob die täglichen Backups der Server rund laufen.
