9 amadmin
\14 administrative interface to control Amanda backups
13 amadmin config command [command options] [ -o | configoption ]*
17 Amadmin performs various administrative tasks on the config Amanda
19 See the amanda(8) man page for more details about Amanda.
23 Commands that take a hostname [ disks ] parameter pair operate on all disks in
24 the disklist for that hostname if no disks are specified. Where hostname is
25 also marked as being optional, the command operates on all hosts and disks in
26 the disklist. Both hostname and disks are special expressions, see the "HOST &
27 DISK EXPRESSION" section of amanda(8) for a description.
31 Show the current version and some compile time and runtime parameters.
32 The config parameter must be present but is ignored.
34 force-bump [ hostname [ disks ]* ]+
35 Force the disks on hostname to bump to a new incremental level during the
38 force-no-bump [ hostname [ disks ]* ]+
39 Force the disks on hostname to not bump to a new incremental level during
42 unforce-bump [ hostname [ disks ]* ]+
43 Undo a previous force-bump or force-no-bump command.
45 force [ hostname [ disks ]* ]+
46 Force the disks on hostname to do a full (level 0) backup during the next
49 unforce [ hostname [ disks ]* ]+
50 Undo a previous force command.
52 reuse tapelabel [ ... ]
53 The tapes listed will be available for reuse at their point in the tape
56 no-reuse tapelabel [ ... ]
57 The tapes listed will not be reused when their turn comes up again in the
58 tape cycle. Note that if this causes the number of reusable tapes to drop
59 below the amanda.conf tapecycle value, Amanda will request new tapes
60 until the count is satisfied again.
62 due [ hostname [ disks ]* ]*
63 Show when the next full dump is due.
65 find [ --sort hkdlpb ] [ hostname [ disks ]* ]*
66 Display all backups currently on tape or in the holding disk. The tape
67 label or holding disk filename, file number, and status are displayed.
68 The --sort option changes the sort order using the following flags:
69 hhost name kdisk name ddump date lbackup level p dump part btape label
70 An uppercase letter reverses the sort order for that key. The default
73 delete [ hostname [ disks ]* ]+
74 Delete the specified disks on hostname from the Amanda database.
78 If you do not also remove the disk from the disklist file, Amanda will
79 treat it as a new disk during the next run.
82 Display the tape(s) Amanda expects to write to during the next run. See
86 Display the current bump threshold parameters, calculated for all backup
89 balance [ --days <num> ]
90 Display the distribution of full backups throughout the dump schedule.
92 export [ hostname [ disks ]* ]*
93 Convert records from the Amanda database to a text format that may be
94 transmitted to another Amanda machine and imported.
97 Convert exported records read from standard input to a form Amanda uses
98 and insert them into the database on this machine.
100 disklist [ hostname [ disks ]* ]*
101 Display the disklist information for each of the disks on hostname (or
102 all hosts). Mostly used for debugging.
104 info [ hostname [ disks ]* ]*
105 Display the database record for each of the disks on hostname (or all
106 hosts). Mostly used for debugging.
109 See the "CONFIGURATION OVERWRITE" section in amanda(8).
114 Request three specific file systems on machine-a get a full level 0 backup
115 during the next Amanda run.
117 $ amadmin daily force machine-a / /var /usr
118 amadmin: machine-a:/ is set to a forced level 0 tonight.
119 amadmin: machine-a:/var is set to a forced level 0 tonight.
120 amadmin: machine-a:/usr is set to a forced level 0 tonight.
122 Request all file systems on machine-b get a full level 0 backup during the next
125 $ amadmin daily force machine-b
126 amadmin: machine-b:/ is set to a forced level 0 tonight.
127 amadmin: machine-b:/var is set to a forced level 0 tonight.
128 amadmin: machine-b:/usr is set to a forced level 0 tonight.
129 amadmin: machine-b:/home is set to a forced level 0 tonight.
131 Undo the previous force request for /home on machine-b. The other file systems
132 will still get a full level 0 backup.
134 $ amadmin daily unforce machine-b /home
135 amadmin: force command for machine-b:/home cleared.
137 Locate backup images of /var from machine-c. The tape or file column displays
138 either a tape label or a filename depending on whether the image is on tape or
139 is still in the holding disk. If the image is on tape, the file column tells
140 you which file on the tape has the image (file number zero is a tape label).
141 This column shows zero and is not meaningful if the image is still in the
142 holding disk. The status column tells you whether the backup was successful or
143 had some type of error.
145 $ amadmin daily find machine-c /var
146 date host disk lv tape or file file part status
147 2000\-11\-09 machine\-c /var 0 000110 9 -- OK
148 2000\-11\-08 machine\-c /var 2 000109 2 -- OK
149 2000\-11\-07 machine\-c /var 2 /amanda/20001107/machine-c._var.2 0 OK
150 2000\-11\-06 machine\-c /var 2 000107 2 -- OK
151 2000\-11\-05 machine\-c /var 2 000106 3 -- OK
152 2000\-11\-04 machine\-c /var 2 000105 2 -- OK
153 2000\-11\-03 machine\-c /var 2 000104 2 -- OK
154 2000\-11\-02 machine\-c /var 2 000103 2 -- OK
155 2000\-11\-01 machine\-c /var 1 000102 5 -- OK
156 2000\-10\-31 machine\-c /var 1 000101 3 -- OK
158 Forget about the /workspace disk on machine-d. If you do not also remove the
159 disk from the disklist file, Amanda will treat it as a new disk during the next
162 $ amadmin daily delete machine-d /workspace
163 amadmin: machine-d:/workspace deleted from database.
164 amadmin: NOTE: you'll have to remove these from the disklist yourself.
166 Find the next tape Amanda will use (in this case, 123456).
169 The next Amanda run should go onto tape 123456 or a new tape.
171 Show how well full backups are balanced across the dump cycle. The due-date
172 column is the day the backups are due for a full backup. #fs shows the number
173 of filesystems doing full backups that night, and orig KB and out KB show the
174 estimated total size of the backups before and after any compression,
176 The balance column shows how far off that night's backups are from the average
177 size (shown at the bottom of the balance column). Amanda tries to keep the
178 backups within +/- 5%, but since the amount of data on each filesystem is
179 always changing, and Amanda will never delay backups just to rebalance the
180 schedule, it is common for the schedule to fluctuate by larger percentages. In
181 particular, in the case of a tape or backup failure, a bump will occur the
182 following night, which will not be smoothed out until the next pass through the
184 The last line also shows an estimate of how many Amanda runs will be made
185 between full backups for a file system. In the example, a file system will
186 probably have a full backup done every eight times Amanda is run (e.g. every
