B-4 Other Precautions
Tape Media
The following describes data handling with the DAT, DLT, or AIT optionally available for the
server.
Saving your valuable data
When you save your valuable data or programs into the cartridge tape, you should save
them into two cartridge tapes to make the primary and secondary tapes.
This enables you to restore your data from one tape when the other makes a read error, as
well as to protect your valuable data and programs from loss.
Three-generation data management
NEC recommends that you should employ three-generation data management for data
storage.
Three-generation data management uses three cartridge tapes: A, B, and C. You save data
to tape A on the first day, tape B on the second day, tape C on the third day, tape A on the
forth day, and so on. That is, you save data into cartridge tapes cyclically from tape A
through C.
This enables you, for example, to use tape B to restore the data when tape C makes a read
error. Also when both tapes B and C make a read error, you can restore your valuable data
by using the data stored in tape A.
