Disks already mounted in the DD
storage.
Concurrent Data Access to the
Disks.

Data Domain is a combination of
a server and Disk Array Enclosures
installed in the Data Centre.
Required proper cooling and
Redundant power input
(no overhead).
Less administration tasks after the
initial setup.
Slower, Backup to shared Tape with

is a Mechanical/Motorized control,
which takes long time.
Sequential Data Access to the

in the library takes long time.
Sequential Data Access to the
Magnetic Tapes.
Highly susceptible to wear and tear
