AMDUMP(8) System Administration Commands AMDUMP(8)NAMEamdump - back up all disks in an Amanda configuration
SYNOPSISamdump [--no-taper] [--exact-match] [-o configoption...] config
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.
Specify the host and disk on which the command will work -- see the
description of DLE specifications in amanda-match(7).
The host and disk are parsed as exact values
See the "CONFIGURATION OVERRIDE" section in amanda(8).
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
