Datensicherung ist selbst für Hobby-Fotografen ein sehr wichtiges, und oft vernachlässigtes Thema. Von Paranoia bis Leichtsinn reicht die Spannweite. Gute Sicherungsmethoden schlagen finanzielle Kerben und sind oft auch aufwändig.

Vor welchen Situationen sichern

  • Umwelteinflüsse/höhere Gewalt
    • Wasser
    • Feuer
    • Blitzschlag
  • Diebstahl
  • Hardwarefehler
  • Softwarefehler
  • Bedienungsfehler

Sicherungsmethoden

Nicht jede Sicherungsmethode ist für jedes Szenario geeignet.

  • Einsatz fehlertoleranter Systeme (RAID 1/5/6)
  • Anfertigen von Sicherungskopien
  • Auslagerung von Sicherungskopien


Welches System halte ich für empfehlenswert

  • RAID 1/5/6 System
    Dieses System schützt vor dem Ausfall der Hardware (Festplatte). Für den Betrieb sind mindestens 2 gleiche Festplatten notwändig. Die Daten und Prüfsummen werden intelligent auf die Platten verteilt. Beim Ausfall von 1 Platte oder einem Teil davon, braucht nur eine gleichwertige Platte wieder eingesetzt werden. Dann restauriert sich das System wieder von selbst.
    Dieses System schützt nicht vor dem gleichzeitigen Ausfall mehrerer Platten oder vor Bedienungsfehlern oder Schäden durch Virenbefall.
  • Sicherung auf eine externe Festplatte, die nur zu Sicherungs/Restore-Tätigkeiten zum Einsatz kommt.
  • Sicherung auf DVD-RAM
    Die Sicherung der Daten auf diesen Medientyp finde ich aus folgenden Überlegungen sinnvoll:
    • längere Lebensdauer als DVD-R oder DVD-RW
    • höhere Datensicherheit durch besseres Fehlermanagement und durch read-after - d.h. die Daten werden nach dem Schreiben verifiziert
    • Bedienung wie eine Festplatte
    • schützt vor Benutzerfehlern und Schäden durch Viren (auf jeden Fall viel mehr, als eine externe Festplatte) - Empfehlenswert ist die Aktivierung des Schreibschutzes und/oder die Verwendung eines (DVD-RAM geeignetem) ROM-Laufwerks.
