– 19 –

Cartridge Life

Data cartridges are subject to wear during every read and write operation. Continuing to use a cartridge eventually leads to errors, and further use could result in loss of stored data. Cartridges should therefore be replaced periodically. The useful life of a cartridge depends on the operating environment, but the following table serves as an approximate guideline to cartridge life.

Usage Frequency Estimated Useful Life

Once per week One year

Two to three times per week Six months

Daily Three months

! The above estimates may be shortened by operating environment conditions

(temperature, humidity, dust, etc.)

To manage data cartridges for optimum useful life, we recommend the following steps:

! Assign control numbers to new data cartridges, and write the numbers on the labels. ! Maintain a tape control list, including the date of first use and the expected useful life of

each cartridge.

! Refer to the control list and tape labels to determine when cartridges are reaching the

end of their useful lives (or if read/write errors occur), and remove them from use. The chemical compounds that compose the magnetic layer of the tape will deteriorate over time. The rate of this deterioration is greatly influenced by the storage environment (temperature and humidity), so even if never used, cartridges should be replaced about three years after purchase.

Preserving Critical Data

To preserve critical data or programs, we recommend saving to two tapes: a main and a sub copy. Also, when writing the backup copies, we recommend confirming the copy by using the verify function of the backup software. Please refer to the documentation for the backup software regarding use of the verify function. By taking these steps, even if read errors are encountered as a result of dirt or dust on the tape, the other tape can be used for data recovery, preventing loss of critical data and programs.

Three-Generation Data Management

We recommend using a three-generation data management system for backing up data saved on disk. This system uses three tapes (call them A, B and C), with the disk data saved in the order A-B-C as follows: disk data is saved to tape A on the first day, tape B on the second day, and tape C on the third day. With this system, if, for example, a read error was found on tape C, most data could still be restored from tape B, and even if a read error was found on tape B, important data could still be restored from tape A.
