Tape Physical Characteristics
The drive can be a stand alone unit which can be connected to a system and
the user will manually insert and swap the tape cartridges as required.
The autoloader contains one tape drive and robotics that can insert and
change the tapes. This system is ideal when one drive is sufficient for the
read/write performance requirement, but multiple tapes will be required for
either capacity or version control.
The tape library contains multiple tape drives and robotics that can insert and
change the tapes. This system is ideal when multiple drives are required to
maintain the read/write performance requirement, and multiple tapes are
required for either capacity or version control.
The solution used will depend on the business and application requirements.
If an application needs to be backed up each night, and the amount of
data to be stored will fit on a single tape and the window is such that a
single drive can support the transfer, then an autoloader will meet the
requirement and not require any manual intervention.
