NAME

       amadmin - administrative interface to control Amanda backups

SYNOPSIS

       amadmin [-o configoption...] config command [command_options...]

DESCRIPTION

       Amadmin performs various administrative tasks on the config Amanda configuration.

       See the amanda(8) man page for more details about Amanda.

COMMANDS

       Commands that take a hostname [ disks ] parameter pair operate on all disks in the disklist(5) for that hostname if no disks are specified.
       Where hostname is also marked as being optional, the command operates on all hosts and disks in the disklist(5) when no hostname is given.
       Both hostname and disks are match expressions; see amanda-match(7) for a description.

       version
	   Show the current version and some compile time and runtime parameters. The config parameter must be present but is ignored.

       estimate [ hostname [ disks ]* ]*
	   Print the server estimate for the dles, each output lines have the following format:
	     hostname diskname level size

	   hostname
	       The quoted hostname

	   diskname
	       The quoted diskname

	   level
	       The level of the estimate

	   size
	       The estimate size in kbytes

       force-bump [ hostname [ disks ]* ]+
	   Force the disks on hostname to bump to a new incremental level during the next Amanda run.

       force-no-bump [ hostname [ disks ]* ]+
	   Force the disks on hostname to not bump to a new incremental level during the next Amanda run.

       unforce-bump [ hostname [ disks ]* ]+
	   Undo a previous force-bump or force-no-bump command.

       force [ hostname [ disks ]* ]+
	   Force the disks on hostname to do a full (level 0) backup during the next Amanda run.

       unforce [ hostname [ disks ]* ]+
	   Undo a previous force command.

       reuse tapelabel [ ... ]
	   The tapes listed will be available for reuse at their point in the tape cycle.

       no-reuse tapelabel [ ... ]
	   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 amanda.conf tapecycle value, Amanda will request new tapes until the count is satisfied again.

	   Tape marked no-reuse are available for recovery, marking them no-reuse is a security to be sure amanda will not overwrite them.

       due [ hostname [ disks ]* ]*
	   Show when the next full dump is due.

       find [ --sort hkdlpbfw ] [ hostname [ disks ]* ]*
	   Display all backups currently on tape or in the holding disk. The tape label or holding disk filename, file number, and status are
	   displayed.

	   The --sort option changes the sort order using the following flags:

	   h: host name
	   k: disk name
	   d: dump timestamp
	   l: backup level
	   p: dump part
	   b: tape label
	   f: filenum on tape
	   w: write timestamp

	   An uppercase letter reverses the sort order for that key. The default sort order is hkdlpbfw.

       holding delete hostname [ disk [ datestamp [ .. ] ] ]
	   Delete holding files matching the given specification. At least a hostname must be provided.

       holding list [-l] [-d] [ hostname [ disk [ datestamp [ .. ] ] ] ]
	   List holding files matching the given dump specification, or all holding files if no specification is provided. See amanda-match(7) 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.

	   An outdated holding file is one which is not required for a restore of the most recent 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.

       delete [ hostname [ disks ]* ]+
	   Delete the specified disks on hostname from the Amanda database.

	       Note
	       If you do not also remove the disk from the disklist(5) file, Amanda will treat it as a new disk during the next run.

       tape
	   Display the tape(s) Amanda expects to write to during the next run. See also amcheck(8).

       bumpsize
	   Display the current bump threshold parameters, calculated for all backup levels.

       balance [ --days <num> ]
	   Display the distribution of full backups throughout the dump schedule.

       export [ hostname [ disks ]* ]*
	   Convert records from the Amanda database to a text format that may be transmitted to another Amanda machine and imported.

       import
	   Convert exported records read from standard input to a form Amanda uses and insert them into the database on this machine.

       disklist [ hostname [ disks ]* ]*
	   Display the disklist(5) information for each of the disks on hostname (or all hosts). Mostly used for debugging.

       hosts
	   Output a list of distinct hosts in the disklist(5), one per line, for easy use in shell scripts.

       dles
	   Output a list of distinct DLEs in the disklist(5), one per line with host and diskname separated by a space, for easy use in shell
	   scripts.

       info [ hostname [ disks ]* ]*
	   Display the database record for each of the disks on hostname (or all hosts). Mostly used for debugging.

       -o configoption
	   See the "CONFIGURATION OVERRIDE" section in amanda(8).

EXAMPLES

       Request three specific file systems on machine-a get a full level 0 backup during the next Amanda run.
       $ amadmin daily force machine-a / /var /usr
       amadmin: machine-a:/ is set to a forced level 0 tonight.
       amadmin: machine-a:/var is set to a forced level 0 tonight.
       amadmin: machine-a:/usr is set to a forced level 0 tonight.

       Request all file systems on machine-b get a full level 0 backup during the next Amanda run.
       $ amadmin daily force machine-b
       amadmin: machine-b:/ is set to a forced level 0 tonight.
       amadmin: machine-b:/var is set to a forced level 0 tonight.
       amadmin: machine-b:/usr is set to a forced level 0 tonight.
       amadmin: machine-b:/home is set to a forced level 0 tonight.

       Undo the previous force request for /home on machine-b. The other file systems will still get a full level 0 backup.
       $ amadmin daily unforce machine-b /home
       amadmin: force command for machine-b:/home cleared.

       Locate backup images of /var from machine-c. The tape or file 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 file 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 status
       column tells you whether the backup was successful or had some type of error.
       $ amadmin daily find machine-c /var
       date	   host      disk lv tape or file		  file part  status
       2000-11-09  machine-c /var  0 000110			  9   --  OK
       2000-11-08  machine-c /var  2 000109			  2   --  OK
       2000-11-07  machine-c /var  2 /amanda/20001107/machine-c._var.2	0 OK
       2000-11-06  machine-c /var  2 000107			  2   --  OK
       2000-11-05  machine-c /var  2 000106			  3   --  OK
       2000-11-04  machine-c /var  2 000105			  2   --  OK
       2000-11-03  machine-c /var  2 000104			  2   --  OK
       2000-11-02  machine-c /var  2 000103			  2   --  OK
       2000-11-01  machine-c /var  1 000102			  5   --  OK
       2000-10-31  machine-c /var  1 000101			  3   --  OK

       Forget about the /workspace disk on machine-d. If you do not also remove the disk from the disklist(5) file, Amanda will treat it as a new
       disk during the next run.
       $ amadmin daily delete machine-d /workspace
       amadmin: machine-d:/workspace deleted from database.
       amadmin: NOTE: you'll have to remove these from the disklist(5) yourself.

       Find the next tape Amanda will use (in this case, 123456).
       $ amadmin daily tape
       The next Amanda run should go onto tape 123456 or a new tape.

       Show how well full backups are balanced across the dump cycle. The due-date column is the day the backups are due for a full backup.  #fs
       shows the number of filesystems doing full backups that night, and orig KB and out KB show the estimated total size of the backups before
       and after any compression, respectively.

       The balance 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.

       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).
       $ amadmin daily balance
	due-date  #fs	orig KB    out KB  balance
