293 Show how well full backups are balanced across the dump cycle. The
295 column is the day the backups are due for a full backup.
297 shows the number of filesystems doing full backups that night, and
301 show the estimated total size of the backups before and after any compression, respectively.
305 column shows how far off that night's backups are from the average size (shown at the bottom of the balance column).
307 tries to keep the backups within +/- 5%, but since the amount of data on each filesystem is always changing, and
309 will never delay backups just to rebalance the schedule, it is common for the schedule to fluctuate by larger percentages. In particular, in the case of a tape or backup failure, a bump will occur the following night, which will not be smoothed out until the next pass through the schedule.
311 The last line also shows an estimate of how many
313 runs will be made between full backups for a file system. In the example, a file system will probably have a full backup done every eight times
315 is run (e.g. every eight days).
