The

-\fBdiskname\fR,
-\fBdatestamp\fR, and
-\fBlevel\fR
-dump pattern-matching works as in
-\fBamrestore\fR(8), with the added requirement that at minimum a
-\fBhostname\fR
-must be specified when not in inventory mode.
+\fIhostname\fR,
+\fIdiskname\fR,
+\fIdatestamp\fR, and

+dump specifications are further described in
+\fBamanda-match\fR(7)\&. Note that at minimum a
+\fIhostname\fR
+must be specified\&.

Unless

is used, backup images are extracted to files in the current directory named:
.PP
-\fBhostname.diskname.datestamp.dumplevel\fR

+.RS 4
Pipe exactly one complete dump file to
-\fBstdout\fR, instead of writing the file to disk. This will restore only the first matching dumpfile (where "first" is determined by the dump log search facility).
-.TP
-\fB-d\fR \fIdevice\fR
-Restore from this tape device instead of the default.
-.TP
-\fB-O\fR \fIdirectory\fR
-Output restored files to this directory, instead of to the current working directory.
-.TP
-\fB-c\fR
-Compress output, fastest method available.
-.TP
-\fB-C\fR
-Compress output, smallest file size method available.
-.TP
-\fB-l\fR
-Leave dumps in the compressed/uncompressed state in which they were found on tape. By default,
-\fBamfetchdump\fR
-will automatically uncompress when restoring.
-.TP
-\fB-a\fR
-Assume that all tapes are already available, via tape changer or otherwise, instead of prompting the operator to ensure that all tapes are loaded.
-.TP
-\fB-i\fR \fIfilename\fR
-Generate an inventory of all dumps "seen" on the tapes we search, for later use as a log.
-.TP
-\fB-w\fR
-Wait to put split dumps together until all chunks have been restored. Normally,
-\fBamfetchdump\fR
-will attempt to read pieces of a split file from tape in order, so that it can assemble them simply by appending each file to the first. This option disables the appending behavior, and instead restores each piece as an individual file and reassembles them only after all have been restored.

-\fBNote\fR
-This requires at least double the size of your dump in free
-disk space, in order to build the final assembled dumpfile.This behavior is implicitly invoked in circumstances where knowing the location of all dumps on tape in advance is not possible, such as when you are restoring without log files.
-.TP
-\fB-n\fR
-Do not reassemble split dump files at all, just restore each piece as an individual file.
-.TP
-\fB-s\fR
-Do not fast-forward straight to needed files on tape. This will slow down most restores substantially. Only use this option if your tape drive does not properly support the fast-forward operation.
-.TP
-\fB-b\fR \fIblocksize\fR
-Force a particular block size when reading from tapes. This value will usually be autodetected, and should not normally need to be set.
