■ Computer performance — The lower the performance of the computer,
the more likely that streaming cannot be maintained and that an
increase in the number of passes over given areas of a cassette
will occur.
■ Backup Software — The backup software may frequently access certain
areas of a cassette, or there may be a high system overhead that can
cause streaming to stop. Both of these factors increase the number of
cassette passes in a given area.
Because these parameters vary from system to system, it is difficult to give a
definitive statement of the number of backup operations achievable using a
particular cassette.
As a guideline, Compaq recommends using a cassette for approximately 75
backup operations in worst-case conditions such as those listed above.
