9.5 Backup
This server utilizes high-reliability components and hard disks, however, as a
precautionary measure, it is recommended that periodic backups be taken of the
data.
9.5.1 Importance of Backups
A backup of data stored on the server is required for data restoration in the event of server trouble
resulting in a system failure or accidental data loss due to operational errors. If the data on the server is
backed up, it can be restored from the backup in the event of hardware failures or data corruption in hard
disks due to operational errors. If backups are not made, restoration is impossible and data will be
permanently lost. To prepare for unexpected problems, be sure to perform periodic backups of the
system.
9.5.2 Backup Devices, Software and Their Operations
Backup operations differ depending on network operating systems, applications, and system operations.
Contact an office listed in the "Contact Information" of "Start Guide" and make backups using the
following items.
• Backup device
• Backup software
(Standard backup software supplied with the OS, e.g., ARCserve, Changer Option)
• Backup operations (schedules)
Use our genuine backup devices and software. Observe the backup medium (tape) storage conditions.
` Mirroring/disk array systems
To improve system reliability, a mirroring or disk array system using an array controller, in addition to
periodic backup creation, is recommended.
Notes on Operating Backups
