Automigration Policy - HP 12000 Design Manual

creates matching virtual cartridges in the virtual library specified for the echo copy pool the physical
tape is in. See
Figure 35 Linked Media
When virtual tapes are ejected by a backup application, or when tapes are ejected in the destination
library, the matching virtual tapes are moved to the device's firesafe — a temporary holding place.
This ensures the device does not fill up its disk space with older cartridges.
When virtual media is ejected, the matching destination tapes are also automatically ejected. If a
destination tape is ejected while a copy is pending, notifications in the VLS GUI will inform the
user that they have interrupted the copy process. However, if the user selected the Echo Copy on
Mailslot Eject option and ejects a tape mid-copy, the copy job increases in priority and completes
as soon as possible before the tape is ejected. See

Automigration Policy

Data written to virtual cartridges is automatically copied onto matching destination tapes based
on the automigration policy. See
Figure 36 Automigration Policy Details
The automigration policy defines the following for each source virtual library:
Retention days – the number of days information is kept in the firesafe before it is deleted.
The default is 2 days.
While virtual cartridges are in the firesafe, they can be used to access data without having
to restore from a physical copy. However, as far as the backup application is concerned,
these cartridges are no longer present. Therefore, to restore data from virtual cartridges in the
