-\fBAmrestore\fR extracts backup images from the tape mounted on \fBtapedevice\fR or from the holding disk file \fBholdingfile\fR that match \fBhostname\fR, \fBdiskname\fR and \fBdatestamp\fR patterns given on the command line\&. The tape or holding file must be in a format written by the \fBamdump\fR or \fBamflush\fR program\&.

-.PP
-If \fBdiskname\fR is not specified, all backups on the tape for the previous \fBhostname\fR are candidates\&. If \fBdatestamp\fR is not specified, all backups on the tape for the previous \fBhostname\fR and \fBdiskname\fR are candidates\&. If no \fBhostname\fR, \fBdiskname\fR or \fBdatestamp\fR are specified, every backup on the tape is a candidate\&.

-\fBHostname\fR and \fBdiskname\fR are special expressions described in the "HOST & DISK EXPRESSION" section of \fBamanda\fR(8)\&. \fBDatestamp\fR are special expression described in the "DATESTAMP EXPRESSION" section of \fBamanda\fR(8)\&. For example, if \fBdiskname\fR is "rz[23]a", it would match disks \fBrz2a\fR and \fBrz3a\fR\&.

.SH "OPTIONS"
-

-\fB\-b\fR

-\fB\-p\fR
-Pipe output\&. The first matching backup image is sent to standard output, which is normally a pipe to \fBrestore\fR or \fBtar\fR, then \fBamrestore\fR quits\&. It may be run again to continue selecting backups to process\&. Make sure you specify the no\-rewind \fBtapedevice\fR when doing this\&.
-
-.PP
-Note: \fBrestore\fR may report "short read" errors when reading from a pipe\&. Most versions of \fBrestore\fR support a blocking factor option to let you set the read block size, and you should set it to 2\&. See the example below\&.

-\fB\-c\fR
-Compress output using the fastest method the compression program provides\&. \fBAmrestore\fR normally writes output files in a format understood by \fBrestore\fR or \fBtar\fR, even if the backups on the tape are compressed\&. With the \fB\-c\fR or \fB\-C\fR option, \fBamrestore\fR writes all files in compressed format, even if the backups on the tape are not compressed\&. Output file names will have a \&.Z or \&.gz extension depending on whether \fBcompress\fR or \fBgzip\fR is the preferred compression program\&. This option is useful when the current directory disk is small\&.
