Storing Important Data; Managing 3-Generation Data; Data Cartridge Storage; Establishing Backup And Disaster Recovery Procedures - NEC N8151-60 User Manual

Storing Important Data

When storing important data or programs, it is strongly recommended that you should
prepare and store the master tape and copy (backup) tape just in case.
Further, we recommend that you verify backup software when saving, and check saved
data. For details on verification, refer to the instruction manual for the backup software you
are using.
By doing this, if one of the tapes causes a read error due to dust or dirt, you can recover the
data from the other tape. Thus, you can prevent loss of important data and programs.

Managing 3-generation Data

To store the data on the disk, you should manage the data in the three generations.
To manage the 3-generation data, use three tapes (A, B, C). On the first day, store the data
on the disk in tape A. On the second day, store the data in tape B. On the third day, store the
data in tape C.
This method allows you to protect your important data. For example, if tape C generates a
read error, you can use tape B to recover the data. If tape B generates a read error, you can
use tape A to recover the data.

Data cartridge storage

Always store data cartridges in a clean location under the specified storage conditions.
Enabling the write-protect feature is recommended when storing data cartridges.
When storing data cartridges for an extended period of time, data should be read
periodically in order to ensure that restoration from backup data is possible at all times.
Storing data cartridges in a different location from the system is recommended. If both
master and spare data cartridges are kept, storing each in a different location is
recommended.
Establishing backup and disaster
recovery procedures
When deciding on a backup method, be sure to make a schedule for image disaster
recovery. Establishing the appropriate backup procedure is the first step in employing
backup. After establishing your disaster recovery procedure, verify it periodically to ensure
that it works correctly.
