To export to attached tape storage device
Data can only be exported from the mail slot. Once data has been exported it is removed from
the HP D2D Backup System. However, if an error occurs during the process, the data is not deleted.
It remains on the cartridge located in the mail slot.
Export
is not recommended with deduplicating
libraries as it does very little to free up disk space, which is the prime reason for export. (Space
is only freed up, if a chunk of data is no longer referenced by any cartridges.)
The preferred option is to use the backup application on the host to move the cartridge into the
mail slot. This action removes the cartridge from the numbered slot and leaves the slot empty and
also ensures that the backup application is in sync with the status of cartridges on the HP D2D.
Backup applications have a number of terms to describe this action, such as remove or eject. Refer
to the documentation supplied with your backup application for further details. You can also move
cartridges manually from the Web Management Interface, see
Cartridges (Virtual Tape
Devices) (page 18)
.
CAUTION:
Do not export cartridges that the backup application uses on a frequent basis as part
of a rotation strategy.
1.
Click on the mail slot in the Cartridge list and press the
Next
button.
NOTE:
The Export function is only active if the mail slot contains a cartridge with data on it
(there is an Export label in the right column of the mail slot).
2.
This displays the second page of the wizard. (Or reports an error if no tape storage devices
are currently attached to the HP D2D Backup System.)
3.
Select the
attached tape drive
from the pull-down list, the required
physical slot
if it is a tape
library, the required
verify/compare option
and whether the physical cartridge should be
unloaded
after the operation completes.
NOTE:
A
Full Verify
reads the data back after copy and compares it byte-by-byte with the
original. A
Quick Verify
also reads back the data, but only ensures that it can be read. It may
save some time if another tape device on the HP D2D Backup System is being accessed at
the same time as the copy operation.
No Verify
is the fastest option.
NOTE:
On physical tape libraries the
unload after completion
option moves the cartridge
to the mail slot, if the mail slot is enabled and empty.
4.
Click
Create
.
NOTE:
You cannot select a cartridge from a Replicating Target Library for export. The Role
column in the Devices section tells you what sort of library you have selected.
5.
The process warns you that the cartridge data on the HP D2D Backup System will be removed
once it has been exported. You must click OK to continue. It also checks that media is loaded
in the attached tape storage device and that it is blank. If it is not blank, you are given the
option of overwriting it or canceling the job. Finally, it checks that there is cartridge data in
the slot to be exported (it may have been subsequently moved by the backup application.)
