7. Politiche di backup
Frequency = backup solo se modificato dall’ultimo backup
Versions Data Exists = Copie di backup
Versions Data Deleted = 1 Copie di backup se il file viene cancellato
Retain Extra Versions = 180 Durata in giorni della copia extra
Retain Only Version = Durata in giorni di una solo copia
Copy Serialization = Shared Static Il file non deve essere in uso durante il backup
Copy Mode = modified Il file è salvato solo se è stato modificato
