HP D2D100 Backup System - Manual (Page 62)

• For the other weekdays, Monday to Thursday: carry out incremental backups to capture that day’s
changes (one cartridge for each day) and keep each cartridge for a week before overwriting.
Assuming a separate cartridge for each day’s incremental backup, another four autoloader
slots are required.
• On the last day of the month:
• From the host (1) carry out a full backup to one cartridge to capture the month’s work ready
for archiving, this requires one extra slot on the autoloader device (2)
• From the HP D2D Web interface schedule a copy to physical cartridge job (3) to run on the
last day of the month. See “ Cartridge copy ” on page 84 for further details.

This scenario requires nine slots on the autoloader device and a physical cartridge in the attached tape
drive on the last day of the month. The cartridge data remains on both the HP D2D Backup System and
the copy on the physical tape drive can be stored offsite.
