Nachdem wir in Teil 1 unseres kleinen Tutorials Bacula installiert haben, wollen wir nun alles weitere konfigurieren.
1. SQLite-datenbank anlegen
Zuerst muss eine SQLite-Datenbank angelegt werden. Hierzu gibt es ein CMD-File, in welchem die Pfadangabe angepasst werden muss:
H:\Bacula\bin\create_database.cmd
Zeile 5:
ECHO .databases | “H:\Bacula\bin\sqlite3″ %* “H:\Bacula\Work\bacula.db”
Nach dem speichern der Änderung kann das Batch-File aufgerufen werden und die Datenbank wird angelegt. Nun kann der Directory-Service gestartet werden.
Im Pfad Bacula\bin finden sich noch weitere CMD-Files, in denen die Pfadangaben zur Installation überarbeitet werden sollten.
2. Konfiguration der Services

Das Konfig-File bacula-dir.conf ist, wie auch der entsprechende Daemon, sind die “Steuerzentrale” von Bacula. Aus diesem Grund gehen wir ein wenig genauer auf die einzelnen Sections ein. Basis ist unsere Beispieldatei, die mit einigen Anpassungen lauffähig ist und die Userverzeichnisse auf C:\Users unter Win Vista sichert.
Die Erläuterungen hierzu folgen in Teil 3 unseres kleinen Tutorials …

In unseren Beiträgen zum auslesen der Daten eines Wechselrichters und zweier Stromzähler ist bisher ein Netbook zum Einsatz gekommen. Leider hat sich die Hardware, im Zusammenspiel mit Windows XP, als sehr unzuverlässig erwiesen.Da auch der Stromverbrauch eines Netbook nicht zu vernachlässigen ist, haben wir uns für eine neue Lösung entschieden: Ein Raspberry Pi und Linux.
