Most business managers readily understand the
value of their data. The network manager of a corporate data centre
typically manages 2.2 terabytes of backup every day.
Reliability is paramount.
The person who looks after a company's
data bears a heavy burden of responsibility. Although
backing up valuable company data is crucial, it is only half the
solution. You also need to be able to recover this information.
Incresingly, businesses are storing cartridges
using automated libraries, to increase capacity and reduce the need
for human interaction. (32% of data loss is attributed to human
error).
The cartridges are kept in slots and picked for
use in the drive when needed. The autoloader locates any given cartridge
by its barcoded label.
All tapes look and work the same. A tape is made
from metal particles trapped inside a coated binding. The particles
are arranged in tracks along the tape.
The drive writes to the tape by re-arranging the
particles along the tracks into sequences.
The drive reads the data by interpreting
particle position and converting it for the computer to understand.
