• 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. Figure 35 Copying to physical tape as part of a rotation strategy 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.
