Avoiding problems
Backing up data
The hard disk is very effective at storing large amounts of data. However, all your
important data or programs may become unavailable due to disk failures or
erroneous operations, such as accidental formatting. Be sure to create backup
copies of hard disk contents into auxiliary storage such as Network Attached Storage
(NAS) regularly using the copy command or a backup program. Hitachi Data
Systems shall not be liable for any unavailability of data or programs arising from
failure or erroneous operations.
Function of RAID

The Redundant Arrays of Independent Disks (RAID) function is installed on this
system equipment. The security of data protection can be improved by using the
RAID function. When using this system equipment, Hitachi recommends the
RAID function be used.

Be sure to back up the content of the hard disks to an auxiliary source, such as a
Linear Tape-Open (LTO) library device or NAS, regularly using the copy
command and the backup program.
Preventing computer viruses
When a program or data suddenly becomes corrupted, such as an unexpected
operation occurs or an unexpected screen appears, the system equipment may be
infected with a computer virus. A computer virus is a malicious program which
intrudes into the system equipment to make the equipment perform an
uncontrollable operation or to corrupt data or programs. In many cases, the
computer is infected through downloading an unidentified program via the Internet or
using a floppy disk of unknown origin. Avoid these actions as much as possible or
take preventive measures by using a virus-scanning program.
