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

116 \fBforce\-no\-bump\fR
120 \fBforce\fR [ \fIhostname\fR [ \fIdisks\fR ]* ]+
126 to do a full (level 0) backup during the next Amanda run\&.
129 \fBunforce\fR [ \fIhostname\fR [ \fIdisks\fR ]* ]+
136 \fBreuse\fR \fItapelabel\fR [ \&.\&.\&. ]
138 The tapes listed will be available for reuse at their point in the tape cycle\&.
141 \fBno\-reuse\fR \fItapelabel\fR [ \&.\&.\&. ]
143 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
146 value, Amanda will request new tapes until the count is satisfied again\&.
150 are available for recovery, marking them
152 is a security to be sure amanda will not overwrite them\&.
155 \fBdue\fR [ \fIhostname\fR [ \fIdisks\fR ]* ]*
157 Show when the next full dump is due\&.
160 \fBfind\fR [ \fB\-\-sort\fR \fIhkdlpbfw\fR ] [ \fIhostname\fR [ \fIdisks\fR ]* ]*
162 Display all backups currently on tape or in the holding disk\&. The tape label or holding disk filename, file number, and status are displayed\&.
166 option changes the sort order using the following flags:
171 \fId\fR: dump timestamp
172 \fIl\fR: backup level
175 \fIf\fR: filenum on tape
176 \fIw\fR: write timestamp
179 An uppercase letter reverses the sort order for that key\&. The default sort order is
183 \fBholding delete\fR \fIhostname\fR [ \fIdisk\fR [ \fIdatestamp\fR [ \&.\&. ] ] ]
185 Delete holding files matching the given specification\&. At least a hostname must be provided\&.
188 \fBholding list\fR [\-l] [\-d] [ \fIhostname\fR [ \fIdisk\fR [ \fIdatestamp\fR [ \&.\&. ] ] ] ]
190 List holding files matching the given dump specification, or all holding files if no specification is provided\&. See
191 \fBamanda-match\fR(7)
192 for more information on dump specifications\&. With \'\-l\', additional information (size, level, and whether the dump is outdated) is provided\&. With \'\-d\', only outdated dumps are shown\&.
194 An outdated holding file is one which is not required for a restore of the
196 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\&.
199 \fBdelete\fR [ \fIhostname\fR [ \fIdisks\fR ]* ]+
205 from the Amanda database\&.
211 .nr an-no-space-flag 1
218 If you do not also remove the disk from the
220 file, Amanda will treat it as a new disk during the next run\&.
227 Display the tape(s) Amanda expects to write to during the next run\&. See also
233 Display the current bump threshold parameters, calculated for all backup levels\&.
236 \fBbalance\fR [ \fB\-\-days\fR \fI<num>\fR ]
238 Display the distribution of full backups throughout the dump schedule\&.
241 \fBexport\fR [ \fIhostname\fR [ \fIdisks\fR ]* ]*
243 Convert records from the Amanda database to a text format that may be transmitted to another Amanda machine and
250 \fBexport\fRed records read from standard input to a form Amanda uses and insert them into the database on this machine\&.
253 \fBdisklist\fR [ \fIhostname\fR [ \fIdisks\fR ]* ]*
257 information for each of the
261 (or all hosts)\&. Mostly used for debugging\&.
266 Output a list of distinct hosts in the
267 \fBdisklist\fR(5), one per line, for easy use in shell scripts\&.
272 Output a list of distinct DLEs in the
273 \fBdisklist\fR(5), one per line with host and diskname separated by a space, for easy use in shell scripts\&.
276 \fBinfo\fR [ \fIhostname\fR [ \fIdisks\fR ]* ]*
278 Display the database record for each of the
282 (or all hosts)\&. Mostly used for debugging\&.

320 $ amadmin daily unforce machine\-b /home
321 amadmin: force command for machine\-b:/home cleared\&.
324 Locate backup images of
327 \fImachine\-c\fR\&. The
329 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
331 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
333 column tells you whether the backup was successful or had some type of error\&.

352 \fImachine\-d\fR\&. If you do not also remove the disk from the
354 file, Amanda will treat it as a new disk during the next run\&.
356 $ amadmin daily delete machine\-d /workspace
357 amadmin: machine\-d:/workspace deleted from database\&.
358 amadmin: NOTE: you\'ll have to remove these from the \fBdisklist\fR(5) yourself\&.
361 Find the next tape Amanda will use (in this case,
365 The next Amanda run should go onto tape 123456 or a new tape\&.
368 Show how well full backups are balanced across the dump cycle\&. The
370 column is the day the backups are due for a full backup\&.
372 shows the number of filesystems doing full backups that night, and
376 show the estimated total size of the backups before and after any compression, respectively\&.
380 column shows how far off that night\'s 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\&.
382 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)\&.
