205 are special expressions; see the "HOST & DISK EXPRESSION" section of
209 Commands that take one or more
211 parameters operate on the set of dumps specified by all of the expressions\&. See the "DUMP SPECIFICATIONS" section of

219 parameter must be present but is ignored\&.

271 \fBreuse\fR \fItapelabel\fR [ \&.\&.\&. ]
273 The tapes listed will be available for reuse at their point in the tape cycle\&.
276 \fBno\-reuse\fR \fItapelabel\fR [ \&.\&.\&. ]
278 The tapes listed will not be reused when their turn comes up again in the tape cycle\&. Note that if this causes the number of reusable tapes to drop below the
283 will request new tapes until the count is satisfied again\&.
287 are available for recovery, marking them
289 is a security to be sure amanda will not overwrite them\&.
292 \fBdue\fR [ \fIhostname\fR [ \fIdisks\fR ]* ]*
294 Show when the next full dump is due\&.
297 \fBfind\fR [ \fB\-\-sort\fR \fIhkdlpbfw\fR ] [ \fIhostname\fR [ \fIdisks\fR ]* ]*
299 Display all backups currently on tape or in the holding disk\&. The tape label or holding disk filename, file number, and status are displayed\&.
303 option changes the sort order using the following flags:
308 \fId\fR: dump timestamp
309 \fIl\fR: backup level
312 \fIf\fR: filenum on tape
313 \fIw\fR: write timestamp
316 An uppercase letter reverses the sort order for that key\&. The default sort order is
320 \fBholding delete\fR \fIhostname\fR [ \fIdisk\fR [ \fIdatestamp\fR [ \&.\&. ] ] ]
322 Delete holding files matching the given specification\&. At least a hostname must be provided\&.
325 \fBholding list\fR [\-l] [\-d] [ \fIhostname\fR [ \fIdisk\fR [ \fIdatestamp\fR [ \&.\&. ] ] ] ]
327 List holding files matching the given specification, or all holding files if no specification is provided\&. With \'\-l\', additional information (size, level, and whether the dump is outdated) is provided\&. With \'\-d\', only outdated dumps are shown\&.
329 An outdated holding file is one which is not required for a restore of the
331 dump\&. Note that outdated dumps may still be required for restores at earlier dates\&. For example, assume that a DLE had a level 0 on Monday, level 1\'s Tuesday through Thursday, and a level 2 on Friday\&. Then the files required for a restore of Fridays (the most recent) dump are those from Monday (level 0), Thursday (level 1), and Friday (level 2)\&. Tuesday and Wednesday\'s files are outdated\&.

379 \fBbalance\fR [ \fB\-\-days\fR \fI<num>\fR ]
381 Display the distribution of full backups throughout the dump schedule\&.
384 \fBexport\fR [ \fIhostname\fR [ \fIdisks\fR ]* ]*
386 Convert records from the
388 database to a text format that may be transmitted to another
397 \fBexport\fRed records read from standard input to a form
399 uses and insert them into the database on this machine\&.
402 \fBdisklist\fR [ \fIhostname\fR [ \fIdisks\fR ]* ]*
406 information for each of the
410 (or all hosts)\&. Mostly used for debugging\&.
413 \fBinfo\fR [ \fIhostname\fR [ \fIdisks\fR ]* ]*

461 $ amadmin daily unforce machine\-b /home
462 amadmin: force command for machine\-b:/home cleared\&.
465 Locate backup images of
468 \fImachine\-c\fR\&. The
470 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
472 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
474 column tells you whether the backup was successful or had some type of error\&.

499 $ amadmin daily delete machine\-d /workspace

510 The next \fIAmanda\fR run should go onto tape 123456 or a new tape\&.
513 Show how well full backups are balanced across the dump cycle\&. The
515 column is the day the backups are due for a full backup\&.
517 shows the number of filesystems doing full backups that night, and
521 show the estimated total size of the backups before and after any compression, respectively\&.
525 column shows how far off that night\'s backups are from the average size (shown at the bottom of the balance column)\&.
527 tries to keep the backups within +/\- 5%, but since the amount of data on each filesystem is always changing, and
529 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\&.
531 The last line also shows an estimate of how many
533 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
535 is run (e\&.g\&. every eight days)\&.
