Zusammenfassung

Hier wird beschrieben, wie selbst ein Restore vorgenommen werden kann.

Diese Anleitung richtet sich besonders an folgende Zielgruppen:

  • Mitarbeitende

Bconsole

Es gibt eine Konsolenschnittstelle zum Bareos Server. Für einzelne User kann eine zugeschnittene Sicht auf einige Server/Backups erzeugt werden, damit dort auch individuelle Restores selbst möglich sind.

Voraussetzung

  • URZ-Account
  • Zugang zu dem Host bcons.rz.uni-jena.de

  • Berechtigungen für den oder die jeweiligen Client(s)

    Für den Zugang bitte ein Ticket im Servicedesk öffnen.

Anwendung

  1. SSH Login mit eigener Kennung an 'bcons.rz.uni-jena.de'.
  2. Befehl 'bconsole' eingeben.

Nun gibt es dort verschiedene Befehle, die auch mit 'help' abgefragt werden können.

Allgemein

Liste der Befehle, bzw. Hilfe

* help
* help status

Status des Backup Servers

* status dir

Status eines Clients (auch check ob erreichbar)

* status client=floh.rz.uni-jena.de


Liste der Jobs und Backups eines Clients (ggf. mit Beschränkung der letzten Tage)

* list jobs client=floh.rz.uni-jena.de
* list backups client=floh.rz.uni-jena.de
* list backups client=floh.rz.uni-jena.de days=4

Testen, wie viel ein aktuelles Backup benötigen würde:

* estimate job=floh.rz

Anschauen der Konfigurationene in Bareos:

* show client=floh.rz.uni-jena.de
* show job=floh.rz
* show jobs
* show jobdefs=ServerDefaultJob3W
* show fileset=default-win-fs1
* show schedule=3WS

Restore

* restore
* restore client=floh.rz.uni-jena.de

Für die nächste Frage sind vermutlich meist nur die Punkte 2, 5 und 6 relevant.

To select the JobIds, you have the following choices:
     1: List last 20 Jobs run
     2: List Jobs where a given File is saved
     3: Enter list of comma separated JobIds to select
     4: Enter SQL list command
     5: Select the most recent backup for a client
     6: Select backup for a client before a specified time
     7: Enter a list of files to restore
     8: Enter a list of files to restore before a specified time
     9: Find the JobIds of the most recent backup for a client
    10: Find the JobIds for a backup for a client before a specified time
    11: Enter a list of directories to restore for found JobIds
    12: Select full restore to a specified Job date
    13: Cancel
  • 2: um eine Datei (ohne Pfad) zu finden in den unterschiedlichen Backup Versionen

  • 3: wenn man die JobIDs kennt

  • 5: Wiederherstellen der letzten Version

  • 6: Wiederherstellen zu einem bestimmten Zeitpunkt

  • Danach kommt man in einen virtuellen Verzeichnisbaum um die Dateien/Verzeichnisse zu markieren (Befehl mark). Die Auswahl wird dann mit done abgeschlossen.

Nun erfolgt nochmal eine Kontrolle. Normalerweise wird nach /tmp/bareos-restore zurückgesichert. Wenn dies bestätigt wird, startet der Restore. Mit status dir

Beispiel 1
* restore client=floh.rz.uni-jena.de

First you select one or more JobIds that contain files
to be restored. You will be presented several methods
of specifying the JobIds. Then you will be allowed to
select which files from those JobIds are to be restored.

WebUI

Der Restore über eine Weboberfläche wird auch möglich sein, wird aber noch etwas dauern bis diese hier zur Verfügung steht.
