120 The figure is divided into a number of regions.

124 In the figure, the X axis is time, with 0 being the moment
127 The Y axis is divided into 5 regions:
130 How many backups have not been started,
131 how many are waiting on space in the holding disk
132 and how many have been transferred successfully to tape.
135 Percentage of allowed network bandwidth in use.
138 The higher line depicts space allocated on the holding disk to
139 backups in progress and completed backups waiting to be written to tape.
140 The lower line depicts the fraction of the holding disk containing completed
141 backups waiting to be written to tape including the file currently being
143 The scale is percentage of the holding disk.
149 Percentage of active dumpers.

155 or it takes them a long time to generate estimates.
