       amdump - back up all disks in an Amanda configuration

       amdump [--no-taper] [--no-dump] [--no-flush] [--no-vault] [--exact-match]
              [-o configoption...] config [host [disk...]...]

       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

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

           Disable writting to tape, including flush and vault.

           Disable dump operations.

           Disable flush, like setting autoflush to NO for all storages.

           Dump done in this run will be flushed.

           Disable all vault.

           The host and disk are parsed as exact values.

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

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

       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.

       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.

       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
