Service Life; Cartridge Storage - NEC LL030F User Manual

8.4.4 Service Life

The service life of the data cartridge varies greatly depending on operating/storage environment. The
estimated life may be shortened by operating environment conditions (temperature, humidity, dust,
etc.)
□ Create the data cartridge management book. Record the date when each data cartridge is used
and estimate how many years and how often each cartridge is used.
□ Examine the data cartridge management book and index label regularly. Discard the cartridges
having low reliability, for example, those which generate write/read errors.
□ Periodically check the data cartridge records and the cartridge labels, and if they indicate that
the data cartridge at hand has been used for so long that write or read errors may occur due to
degraded reliability, dispose of the data cartridge.

8.4.5 Cartridge storage

□ Maintain the proper storage conditions, and keep the storage area clean.
□ Write protection should be set for cartridges put into storage.
□ If a cartridge is being stored for a long time, the cartridge should be read periodically to
confirm that the backup data remains recoverable.
□ To help ensure safe storage, store cartridges in a location that is far removed from the system in
which the cartridges are used.
