48 BakStor Installation and Administration Manual
5.2 Using an External Tape Device
The BakStor unit can be connected to an external SCSI tape device using the SCSI connections.
This allows for moving data from the BakStor for offsite or archival storage. Standalone tape
drives, tape libraries and autoloaders can be used.
5.2.1 Connecting and Configuring a Stand-Alone Tape Device
In order to use an external tape device it first needs to be connected to the BakStor:
1. Power down the BakStor.
2. Connect the external tape device to the SCSI port on the BakStor. Make sure that proper
SCSI cables and SCSI termination is used.
3. Power up the external tape device.
4. Power up the BakStor.
The tape device is now connected to the BakStor. Verify that the SCSI tape device was correctly
recognized by the BakStor.
Choose Backup Menu ? Tape control menu ? Scan for new tape device
This will provide a list of all tape devices recognized by the BakStor. If a tape library is
connected a tape map of the library will be displayed as well.
If the tape device is not recognized select yes and click the accept button to force the BakStor to
rescan the SCSI bus.
If the tape device is still not recognized power down the BakStor and check the SCSI cables and
the SCSI termination on the SCSI bus.
5.2.2 Formats for moving data to a physical tape
The BakStor can be used to move both diskslices and tapeslices to a physical tape.
For diskslices a direct blocklevel copy of the data from the slice to the physical tape is
performed. The data can be restored from the physical tape to a diskslice on the BakStor.
The data can be moved back to any BakStor unit should the original BakStor unit not be
available.
The BakStor does have an option for encrypting the data before copying the data to a physical
tape. If this option is used a password will be required before data can be copied from the
physical tape.
For tapeslices (Virtual Tapes) there are two options for what format to use when copying data
from the slice to the tape.
The data can either be copied in native mode or in application mode.
Native mode creates a physical tape that is native to the BakStor. This creates a physical tape
