Rest-Server

Verschoben Restic
  • Was das?

    Rest Server is a high performance HTTP server that implements restic's REST backend API. It provides secure and efficient way to backup data remotely, using restic backup client via the rest: URL.

    Installation

    Mittels git das Repo clonen.

    root@rockpro64:~# git clone https://github.com/restic/rest-server.git
    Cloning into 'rest-server'...

    Resolving deltas: 100% (1189/1189), done.
    

    In das Verzeichnis wechseln und mittels go das File bauen. Moment, go fehlt uns noch.

    apt install golang-go
    

    Danach

     cd rest-server
    

    File bauen

    Das resultierende File rest-server an seinen Platz verschieben.

    cp rest-server /usr/local/bin   
    

    Test

    root@rockpro64:/# rest-server --help

    Gut, das Programm läuft 🙂

    Rest-Server starten

    root@rockpro64:/# rest-server --path /home/rock64/backup --no-auth
    Data directory: /home/rock64/backup
    Authentication disabled
    Private repositories disabled
    Starting server on :8000
    

    OK, der Rest-Server läuft. Dann mal ausprobieren.

    Backup erstellen und Test

    Init

    root@frank-MS-7C37:~# restic -r rest:http://192.168.3.11:8000/ init
    enter password for new repository: 
    enter password again: 
    created restic repository 394364201c at rest:http://192.168.3.11:8000/
    
    Please note that knowledge of your password is required to access
    the repository. Losing your password means that your data is
    irrecoverably lost.
    

    backup

    root@frank-MS-7C37:~# restic -r rest:http://192.168.3.11:8000/ backup /home/frank/Dokumente/

    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
    drwxr-xr-x   7 root   root   4.0K May 10 09:47 .
    drwxr-xr-x   5 rock64 rock64 4.0K May 10 09:43 ..
    -rw-------   1 root   root    155 May 10 09:47 config

    drwx------   2 root   root   4.0K May 10 09:49 snapshots
    

    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 ..

    drwx------ 258 root   root   4.0K May 10 09:47 data

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

  • 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.

  • --append-only

    Schützt Backups vor diesen fiesen Dinger, wie heißen die noch in der Windows Welt? Emotet oder so? 🙂

  • Heute mal was Zeit gehabt zum Spielen. Rest-Server aufgesetzt, mittels Letsencrypt die TLS Verbindung eingerichtet und läuft alles. Bin gerade mal mein Home-Verzeichnis am hochladen. Evt. schreibe ich dazu einen separaten Beitrag.

  • Rest-Server in Version v0.10.0 released. Test folgt die Tage..

  • 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.

    Mein kleines Projekt liegt auch noch auf gitlab.com. Man kann prima die beiden Dienste (VSCode & gitlab.com) verknüpfen.

    Eine Änderung, ein commit und dann

    git push origin master

    Und die Änderungen sind oben. Aber, ich stecke da noch ganz am Anfang der Lernkurve 😉

    Wenn ihr alles richtig gemacht habt, dann könnt ihr Euer Zertifikat überprüfen lassen. Sollte dann so aussehen.
