45 <para>Commands that take a <emphasis remap='I'>hostname</emphasis> [ <emphasis remap='I'>disks</emphasis> ]
46 parameter pair operate on all disks in the <emphasis remap='I'>disklist</emphasis> for that
47 <emphasis remap='I'>hostname</emphasis> if no disks are specified. Where
48 <emphasis remap='I'>hostname</emphasis> is also marked as being optional,
49 the command operates on all hosts and disks in the <emphasis remap='I'>disklist</emphasis>.
50 Both <emphasis remap='I'>hostname</emphasis> and <emphasis remap='I'>disks</emphasis>
51 are special expressions; see the "HOST & DISK EXPRESSION" section

55 <para>Commands that take one or more <emphasis remap='I'>dumpspec</emphasis> parameters operate

373 <emphasis remap='I'>due-date</emphasis>
374 column is the day the backups are due for a full backup.
375 <emphasis remap='I'>#fs</emphasis>
376 shows the number of filesystems doing full backups that night, and

379 <emphasis remap='I'>out KB</emphasis>
380 show the estimated total size of the backups
381 before and after any compression, respectively.</para>
384 <emphasis remap='I'>balance</emphasis>
385 column shows how far off that night's backups are from the average size
386 (shown at the bottom of the balance column).
387 &A; tries to keep the backups within +/- 5%,
388 but since the amount of data on each filesystem is always changing,
389 and &A; will never delay backups just to rebalance the schedule,
390 it is common for the schedule to fluctuate by larger percentages.
391 In particular, in the case of a tape or backup failure, a bump will occur the following night,
392 which will not be smoothed out until the next pass through the schedule.</para>
394 <para>The last line also shows an estimate of how many &A; runs will be
395 made between full backups for a file system.
396 In the example, a file system will probably have a full backup done
397 every eight times &A; is run (e.g. every eight days).</para>
