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.
