69 Show the current version and some compile time and runtime parameters\&. The
71 parameter must be present but is ignored\&.
74 \fBestimate\fR [ \fIhostname\fR [ \fIdisks\fR ]* ]*
76 Print the server estimate for the dles, each output lines have the following format:
78 hostname diskname level size
93 The level of the estimate
98 The estimate size in kbytes
102 \fBforce\-bump\fR [ \fIhostname\fR [ \fIdisks\fR ]* ]+
108 to bump to a new incremental level during the next Amanda run\&.
111 \fBforce\-no\-bump\fR [ \fIhostname\fR [ \fIdisks\fR ]* ]+
117 to not bump to a new incremental level during the next Amanda run\&.

125 \fBforce\-no\-bump\fR
129 \fBforce\fR [ \fIhostname\fR [ \fIdisks\fR ]* ]+
135 to do a full (level 0) backup during the next Amanda run\&.

145 \fBreuse\fR \fItapelabel\fR [ \&.\&.\&. ]
147 The tapes listed will be available for reuse at their point in the tape cycle\&.
150 \fBno\-reuse\fR \fItapelabel\fR [ \&.\&.\&. ]
152 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
155 value, Amanda will request new tapes until the count is satisfied again\&.
159 are available for recovery, marking them
161 is a security to be sure amanda will not overwrite them\&.
164 \fBdue\fR [ \fIhostname\fR [ \fIdisks\fR ]* ]*
166 Show when the next full dump is due\&.
169 \fBfind\fR [ \fB\-\-sort\fR \fIhkdlpbfw\fR ] [ \fIhostname\fR [ \fIdisks\fR ]* ]*
171 Display all backups currently on tape or in the holding disk\&. The tape label or holding disk filename, file number, and status are displayed\&.
175 option changes the sort order using the following flags:
180 \fId\fR: dump timestamp
181 \fIl\fR: backup level
184 \fIf\fR: filenum on tape
185 \fIw\fR: write timestamp
188 An uppercase letter reverses the sort order for that key\&. The default sort order is
192 \fBholding delete\fR \fIhostname\fR [ \fIdisk\fR [ \fIdatestamp\fR [ \&.\&. ] ] ]
194 Delete holding files matching the given specification\&. At least a hostname must be provided\&.
197 \fBholding list\fR [\-l] [\-d] [ \fIhostname\fR [ \fIdisk\fR [ \fIdatestamp\fR [ \&.\&. ] ] ] ]
199 List holding files matching the given dump specification, or all holding files if no specification is provided\&. See
200 \fBamanda-match\fR(7)
201 for more information on dump specifications\&. With \*(Aq\-l\*(Aq, additional information (size, level, and whether the dump is outdated) is provided\&. With \*(Aq\-d\*(Aq, only outdated dumps are shown\&.
203 An outdated holding file is one which is not required for a restore of the
205 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\*(Aqs 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\*(Aqs files are outdated\&.
208 \fBdelete\fR [ \fIhostname\fR [ \fIdisks\fR ]* ]+
214 from the Amanda database\&.
220 .nr an-no-space-flag 1
227 If you do not also remove the disk from the
229 file, Amanda will treat it as a new disk during the next run\&.
236 Display the tape(s) Amanda expects to write to during the next run\&. See also
242 Display the current bump threshold parameters, calculated for all backup levels\&.
245 \fBbalance\fR [ \fB\-\-days\fR \fI<num>\fR ]
247 Display the distribution of full backups throughout the dump schedule\&.
250 \fBexport\fR [ \fIhostname\fR [ \fIdisks\fR ]* ]*
252 Convert records from the Amanda database to a text format that may be transmitted to another Amanda machine and
259 \fBexport\fRed records read from standard input to a form Amanda uses and insert them into the database on this machine\&.
262 \fBdisklist\fR [ \fIhostname\fR [ \fIdisks\fR ]* ]*
266 information for each of the
270 (or all hosts)\&. Mostly used for debugging\&.
275 Output a list of distinct hosts in the
276 \fBdisklist\fR(5), one per line, for easy use in shell scripts\&.
281 Output a list of distinct DLEs in the
282 \fBdisklist\fR(5), one per line with host and diskname separated by a space, for easy use in shell scripts\&.
285 \fBinfo\fR [ \fIhostname\fR [ \fIdisks\fR ]* ]*
287 Display the database record for each of the
291 (or all hosts)\&. Mostly used for debugging\&.

329 $ amadmin daily unforce machine\-b /home
330 amadmin: force command for machine\-b:/home cleared\&.
333 Locate backup images of
336 \fImachine\-c\fR\&. The
338 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
340 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
342 column tells you whether the backup was successful or had some type of error\&.

361 \fImachine\-d\fR\&. If you do not also remove the disk from the
363 file, Amanda will treat it as a new disk during the next run\&.
365 $ amadmin daily delete machine\-d /workspace
366 amadmin: machine\-d:/workspace deleted from database\&.
367 amadmin: NOTE: you\*(Aqll have to remove these from the \fBdisklist\fR(5) yourself\&.
370 Find the next tape Amanda will use (in this case,
374 The next Amanda run should go onto tape 123456 or a new tape\&.
377 Show how well full backups are balanced across the dump cycle\&. The
379 column is the day the backups are due for a full backup\&.
381 shows the number of filesystems doing full backups that night, and
385 show the estimated total size of the backups before and after any compression, respectively\&.
389 column shows how far off that night\*(Aqs backups are from the average size (shown at the bottom of the balance column)\&. Amanda tries to keep the backups within +/\- 5%, but since the amount of data on each filesystem is always changing, and Amanda 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\&.
391 The last line also shows an estimate of how many Amanda 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 Amanda is run (e\&.g\&. every eight days)\&.
