.SH "NAME"
amdump - back up all disks in an Amanda configuration
.SH "SYNOPSIS"
.HP 7
\fBamdump\fR \fIconfig\fR [\fIhost\fR\ [\fIdisk\fR...]...] [\-o\ \fIconfigoption\fR]...
.SH "DESCRIPTION"
.PP
\fBAmdump\fR
switches to the appropriate
\fIAmanda\fR
configuration directory, e\.g\. /usr/local/etc/amanda/\fIconfig\fR, then attempts to back up every disk specified by the
\fIamanda\.conf\fR
file\.
\fBAmdump\fR
is normally run by
\fBcron\fR\.
.PP
You can specify many host/disk expressions, only disks that match an expression will be dumped\. All disks are dumped if no expressions are given\.
.PP
If the file /usr/local/etc/amanda/\fIconfig\fR/hold exists,
\fBamdump\fR
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,
\fBamdump\fR
checks for the hold file every minute\.
.PP
See the
\fBamanda\fR(8)
man page for more details about
\fIAmanda\fR\.
.SH "OPTIONS"

\fBamdump\fR
or
\fBamflush\fR
running, or the remains of a previous incomplete
\fBamdump\fR
or
\fBamflush\fR
run\. This run is terminated\. If the problem is caused by the remains of a previous run, you must execute
\fBamcleanup\fR(8)
and then rerun
\fBamdump\fR\.
