.SH "NAME"
amflush - flush Amanda backup files from holding disk to tape
.SH "SYNOPSIS"
.HP 8
\fBamflush\fR [\-b] [\-f] [\-s] [\-D\ \fIdatestamp\fR] \fIconfig\fR [\fIhost\fR\ [\fIdisk\fR...]...] [\-o\ \fIconfigoption\fR]...
.SH "DESCRIPTION"
.PP
\fBAmflush\fR
writes
\fIAmanda\fR
backups from the holding disks to tape, and updates the
\fIAmanda\fR
info database and tapelist accordingly\. Backups may stay in a holding disk when something is wrong with the tape at the time
\fBamdump\fR
is run\. When this happens, the problem must be corrected and
\fBamflush\fR
run by hand\.
.SH "OPTIONS"
.PP
\fB\-b\fR
.RS 4
Run
\fBamflush\fR
in batch mode\. All datestamps are selected unless specified\. The flush is started without confirmation\.
.RE
.PP
\fB\-f\fR
.RS 4
Run
\fBamflush\fR
in foreground\.
\fBAmflush\fR
normally detaches itself from the tty and runs as a background process\. With the
\fB\-f\fR
option,
\fBamflush\fR
stays in the foreground\. This is useful if
\fBamflush\fR
is run as part of another script that, for example, advances the tape after the flush is completed\.
.RE
.PP
\fB\-s\fR
.RS 4
Write log to stdout/stderr instead of the amflush log file\. Requires the
\fB\-f\fR
option\.
.RE
.PP
\fB\-D datestamp\fR
.RS 4
specify a datestamp expression you want to flush, see the "DATESTAMP EXPRESSION" section of
\fBamanda\fR(8)
for a description\.
\fB\-D 20001225\-7\fR
will flush all dumps from 25 december 2000 to 27 december 2000\.
.RE
.PP
\fIhost\fR [\fIdisk\fR]*
.RS 4
Specify the host and disk on which the command will work\.
.RE
.PP
\fB\-o\fR \fIconfigoption\fR
.RS 4
See the "\fBCONFIGURATION OVERRIDE\fR" section in
\fBamanda\fR(8)\.
.RE
.PP
You can specify many host/disk expressions, only disks that match an expression will be flushed\. All disks are flushed if no expressions are given\. see the "HOST & DISK EXPRESSION" section of
\fBamanda\fR(8)
for a description\.
.PP
\fBAmflush\fR
will look in the holding disks specified by the
\fIamanda\.conf\fR
file in /usr/local/etc/amanda/\fIconfig\fR
for any non\-empty
\fIAmanda\fR
work directories\. It then prompts you to select a directory or to process all of the directories\. The work directories in the holding disks are named by the date at the time
\fBamdump\fR
was run, e\.g\.
19910215\.
.PP
See the
\fBamanda\fR(8)
man page for more details about
\fIAmanda\fR\.
.SH "EXAMPLE"
.PP
\fBAmflush\fR
will search for holding areas associated with the
\fIdaily\fR
configuration\. After you select which holding area to flush,
\fBamflush\fR
writes the data to tape, updates the databases and sends a mail report similar to
\fBamdump\fR(8)\.
