298 column tells you which file on the tape has the image

336 <para>Find the next tape &A; will use (in this case, <literal>123456</literal>).</para>
340 The next &A; run should go onto tape 123456 or a new tape.
343 <para>Show how well full backups are balanced across the dump cycle.
345 <emphasis remap='I'>due-date</emphasis>
346 column is the day the backups are due for a full backup.
347 <emphasis remap='I'>#fs</emphasis>
348 shows the number of filesystems doing full backups that night, and
349 <emphasis remap='I'>orig KB</emphasis>
351 <emphasis remap='I'>out KB</emphasis>
352 show the estimated total size of the backups
353 before and after any compression, respectively.</para>
356 <emphasis remap='I'>balance</emphasis>
357 column shows how far off that night's backups are from the average size
358 (shown at the bottom of the balance column).
359 &A; tries to keep the backups within +/- 5%,
360 but since the amount of data on each filesystem is always changing,
361 and &A; will never delay backups just to rebalance the schedule,
362 it is common for the schedule to fluctuate by larger percentages.
363 In particular, in the case of a tape or backup failure, a bump will occur the following night,
364 which will not be smoothed out until the next pass through the schedule.</para>
366 <para>The last line also shows an estimate of how many &A; runs will be
367 made between full backups for a file system.
368 In the example, a file system will probably have a full backup done
369 every eight times &A; is run (e.g. every eight days).</para>
