amdump - back up all disks in an Amanda configuration
[--no-taper] [--exact-match] [ -o configoption...]
config [ host [disk...]...]
is the main interface to the Amanda backup process. It loads the
specified configuration and attempts to back up every disk specified by the
is normally run by cron
The command optionally takes a set of DLE specifications (see
(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
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
Amanda to not start the taper, and thus enter degraded mode immediately.

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
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
