amdump - back up all disks in an AMANDA configuration
amdump config [host [disk...]...]
Amdump switches to the appropriate AMANDA configuration directory, e.g.
/usr/local/etc/amanda/config, then attempts to back up every disk spec-
ified by the amanda.conf file. Amdump is normally run by cron.
You can specify many host/disk expressions, only disks that match an
expression will be dumped. All disks are dumped if no expressions are
If the file /usr/local/etc/amanda/config/hold exists, 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.
See the amanda(8) man page for more details about AMANDA.
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 re-
moved before starting backups.
amdump: amdump or amflush is already running, or you must run amcleanup
Amdump detected another amdump or amflush running, or the re-
mains of a previous incomplete amdump or amflush run. This run
is terminated. If the problem is caused by the remains of a pre-
vious run, you must execute amcleanup(8) and then rerun amdump.
