AMDUMP(8)		System Administration Commands		     AMDUMP(8)

NAME
       amdump -	back up	all disks in an	Amanda configuration

SYNOPSIS
       amdump [--no-taper] [--exact-match] [-o configoption...]	config
	      [host [disk...]...]

DESCRIPTION
       Amdump is the main interface to the Amanda backup process. It loads the
       specified configuration and attempts to back up every disk specified by
       the disklist(5).	 Amdump	is normally run	by cron.

       The command optionally takes a set of DLE specifications	(see amanda-
       match(7)) to narrow the DLEs that will be dumped. All disks are dumped
       if no expressions are given.

       If a file named hold exists in the configuration	directory, amdump will
       wait until it is	removed	before starting	the backups. This allows
       scheduled backups to be delayed when circumstances warrant, for
       example,	if the tape device is being used for some other	purpose. While
       waiting,	amdump checks for the hold file	every minute.

       In some cases it	is desirable to	dump all Amanda	clients	to holding
       disk without writing anything to	storage	media. The --no-taper option
       instructs Amanda	to not start the taper,	and thus enter degraded	mode
       immediately.

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

OPTIONS
       host [disk]*
	   Specify the host and	disk on	which the command will work -- see the
	   description of DLE specifications in	amanda-match(7).

       --exact-match
	   The host and	disk are parsed	as exact values

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

EXAMPLE
       Here is a typical crontab entry.	It runs	amdump every weeknight at 1
       a.m. as user bin:
       0 1 * * 1-5 bin /usr/local/sbin/amdump daily

       Please see the crontab(5) or crontab(1) manual page for the correct
       crontab format for your system.

MESSAGES
       amdump: waiting for hold	file to	be removed
	   The "hold" file exists and amdump is	waiting	for it to be removed
	   before starting backups.

       amdump: amdump or amflush is already running, or	you must run amcleanup
	   Amdump detected another amdump or amflush running, or the remains
	   of a	previous incomplete amdump or amflush run. This	run is
	   terminated. If the problem is caused	by the remains of a previous
	   run,	you must execute amcleanup(8) and then rerun amdump.

EXIT CODE
       The exit	code of	amdump is the ORed value of:
	0  = success
	1  = error
	2  = a dle give	strange	message
	4  = a dle failed
	8  = Don't know	the status of a	dle (RESULT_MISSING in the report)
	16 = tape error	or no more tape
