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
If the data on the server is backed up, it can be restored from the backup data in the event of data
corruption in hard disk units due to hardware failures or operational errors. If backups are not made,
restoration is impossible and your important data will be lost permanently. For anxiety-free system
operation, be sure to perform periodic backups of the system.
9.5.2 Backup Devices, Software and Their Operations
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.
