Incorporating archive to tape into a rotation strategy
Two m ethods are provided for archive a cartridge to the directly attached tape device, these are Copy
and Exp
ort.
• Copy retains the data ca rtridge on the HP D 2D system and creates an exact copy onto a physical
cartridge in the attached tape drive.
• Expor
t removes the data cartridge from the autoloader on the D2D once data h as been
succe
ssfully copied to the physical cartridge in the attached tape drive.
Each method has advantages and disadvantages, as described in more detail in
“Archiving methods”onpage84. Referalsotothewhitepapersonh
ttP://www.hp.com/support for
examples of using these functions with specific backup applications.
This example shows how to incorporate copy to a tape drive connected to the HP D2D Backup System
into
a tape rotation strategy.
• On Friday: carry out a full ba ckup to one cartridge to capture the week’s work and keep that
cartridge for four weeks before overwriting. Assum i ng a sepa rate car tridge for each week’s full
backup, four autoloader slots are required.
