195 Display all backups currently on tape or in the holding disk\&. The tape label or holding disk filename, file number, and status are displayed\&.
199 option changes the sort order using the following flags:
204 \fId\fR: dump timestamp
205 \fIl\fR: backup level
208 \fIf\fR: filenum on tape
209 \fIw\fR: write timestamp
212 An uppercase letter reverses the sort order for that key\&. The default sort order is
216 \fBholding delete\fR \fIhostname\fR [ \fIdisk\fR [ \fIdatestamp\fR [ \&.\&. ] ] ]
218 Delete holding files matching the given specification\&. At least a hostname must be provided\&.
221 \fBholding list\fR [\-l] [\-d] [ \fIhostname\fR [ \fIdisk\fR [ \fIdatestamp\fR [ \&.\&. ] ] ] ]
223 List holding files matching the given dump specification, or all holding files if no specification is provided\&. See
224 \fBamanda-match\fR(7)
225 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 With \*(Aq\-l\*(Aq, additional information (size, level, and whether the dump is outdated) is provided\&. With \*(Aq\-d\*(Aq, only outdated dumps are shown\&.
227 An outdated holding file is one which is not required for a restore of the
229 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 Note that outdated dumps may still be required for restores at earlier dates\&.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 Tuesday and Wednesday\*(Aqs files are outdated\&.

251 If you do not also remove the disk from the
253 file, Amanda will treat it as a new disk during the next run\&.

266 Display the current bump threshold parameters, calculated for all backup levels\&.
269 \fBbalance\fR [ \fB\-\-days\fR \fI<num>\fR ]
271 Display the distribution of full backups throughout the dump schedule\&.
274 \fBexport\fR [ \fIhostname\fR [ \fIdisks\fR ]* ]*
276 Convert records from the Amanda database to a text format that may be transmitted to another Amanda machine and
283 \fBexport\fRed records read from standard input to a form Amanda uses and insert them into the database on this machine\&.
286 \fBdisklist\fR [ \fIhostname\fR [ \fIdisks\fR ]* ]*
290 information for each of the
294 (or all hosts)\&. Mostly used for debugging\&.
299 Output a list of distinct hosts in the
300 \fBdisklist\fR(5), one per line, for easy use in shell scripts\&.
305 Output a list of distinct DLEs in the
306 \fBdisklist\fR(5), one per line with host and diskname separated by a space, for easy use in shell scripts\&.
309 \fBinfo\fR [ \fIhostname\fR [ \fIdisks\fR ]* ]*

354 amadmin: force command for machine\-b:/home cleared\&.
357 Locate backup images of
360 \fImachine\-c\fR\&. The
362 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
364 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
366 column tells you whether the backup was successful or had some type of error\&.

385 \fImachine\-d\fR\&. If you do not also remove the disk from the
387 file, Amanda will treat it as a new disk during the next run\&.
389 $ amadmin daily delete machine\-d /workspace
390 amadmin: machine\-d:/workspace deleted from database\&.
391 amadmin: NOTE: you\*(Aqll have to remove these from the \fBdisklist\fR(5) yourself\&.
394 Find the next tape Amanda will use (in this case,
398 The next Amanda run should go onto tape 123456 or a new tape\&.
401 Show how well full backups are balanced across the dump cycle\&. The
403 column is the day the backups are due for a full backup\&.
405 shows the number of filesystems doing full backups that night, and
409 show the estimated total size of the backups before and after any compression, respectively\&.
413 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\&.
415 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)\&.
