285 column displays either a tape label or a filename depending on whether the image is on tape or is still in the holding disk. If the image is on tape, the
287 column tells you which file on the tape has the image (file number zero is a tape label). This column shows zero and is not meaningful if the image is still in the holding disk. The
289 column tells you whether the backup was successful or had some type of error.

337 Show how well full backups are balanced across the dump cycle. The
339 column is the day the backups are due for a full backup.
341 shows the number of filesystems doing full backups that night, and
345 show the estimated total size of the backups before and after any compression, respectively.
349 column shows how far off that night's backups are from the average size (shown at the bottom of the balance column).
351 tries to keep the backups within +/\- 5%, but since the amount of data on each filesystem is always changing, and
353 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.
355 The last line also shows an estimate of how many
357 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
359 is run (e.g. every eight days).
