123 The tapes listed will be available for reuse at their point in the tape cycle\&.
126 \fBno\-reuse\fR \fItapelabel\fR [ \&.\&.\&. ]
128 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

139 is a security to be sure amanda will not overwrite them\&.
142 \fBdue\fR [ \fIhostname\fR [ \fIdisks\fR ]* ]*
144 Show when the next full dump is due\&.
147 \fBfind\fR [ \fB\-\-sort\fR \fIhkdlpbfw\fR ] [ \fIhostname\fR [ \fIdisks\fR ]* ]*
149 Display all backups currently on tape or in the holding disk\&. The tape label or holding disk filename, file number, and status are displayed\&.
153 option changes the sort order using the following flags:
158 \fId\fR: dump timestamp
159 \fIl\fR: backup level
162 \fIf\fR: filenum on tape
163 \fIw\fR: write timestamp
166 An uppercase letter reverses the sort order for that key\&. The default sort order is
170 \fBholding delete\fR \fIhostname\fR [ \fIdisk\fR [ \fIdatestamp\fR [ \&.\&. ] ] ]
172 Delete holding files matching the given specification\&. At least a hostname must be provided\&.
175 \fBholding list\fR [\-l] [\-d] [ \fIhostname\fR [ \fIdisk\fR [ \fIdatestamp\fR [ \&.\&. ] ] ] ]
177 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 With \'\-l\', additional information (size, level, and whether the dump is outdated) is provided\&. With \'\-d\', only outdated dumps are shown\&.
179 An outdated holding file is one which is not required for a restore of the
181 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 Note that outdated dumps may still be required for restores at earlier dates\&.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 Tuesday and Wednesday\'s files are outdated\&.

227 \fBbalance\fR [ \fB\-\-days\fR \fI<num>\fR ]
229 Display the distribution of full backups throughout the dump schedule\&.
232 \fBexport\fR [ \fIhostname\fR [ \fIdisks\fR ]* ]*
234 Convert records from the
236 database to a text format that may be transmitted to another
245 \fBexport\fRed records read from standard input to a form
247 uses and insert them into the database on this machine\&.

309 $ amadmin daily unforce machine\-b /home
310 amadmin: force command for machine\-b:/home cleared\&.
313 Locate backup images of
316 \fImachine\-c\fR\&. The
318 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
320 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
322 column tells you whether the backup was successful or had some type of error\&.

358 The next \fIAmanda\fR run should go onto tape 123456 or a new tape\&.
361 Show how well full backups are balanced across the dump cycle\&. The
363 column is the day the backups are due for a full backup\&.
365 shows the number of filesystems doing full backups that night, and
369 show the estimated total size of the backups before and after any compression, respectively\&.
373 column shows how far off that night\'s backups are from the average size (shown at the bottom of the balance column)\&.
375 tries to keep the backups within +/\- 5%, but since the amount of data on each filesystem is always changing, and
377 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\&.
379 The last line also shows an estimate of how many
381 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
383 is run (e\&.g\&. every eight days)\&.
