-\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\&.

+\fIAmrestore\fR
+is a very low\-level tool for extracting data from Amanda volumes\&. It does not consult any catalog information or other metadata, basing its operations only on the headers found on the volume\&. This makes it an appropriate tool for bare\-metal restores of an Amanda server, or other situations where the catalog is not available\&.
+.PP
+See
+\fBamfetchdump\fR(8)
+and
+\fBamrecover\fR(8)
+for higher\-level recoveries\&.
+.PP
+The tool does not reassemble split dumps, but can uncompress compressed dumps\&. Note that decompression may fail for split parts after the first\&. If this occurs, extract the parts without decompressing, concatenate them, and decompress the result\&.
+.PP
+Data is restored from the current volume in
+\fIchangerspec\fR, or from the holding file
+\fIholdingfile\fR\&. In most cases,
+\fIchangerspec\fR
+will name a particular device, e\&.g\&.,
+tape:/dev/nst0
+or
+s3:mybucket/tape\-1\&.
+.PP
+Only dumps matching the dump specification beginning with
+\fIhostname\fR
+are extracted\&. If no specification is given, every file on the volume (or the entire holdingfile) is restored\&. See the "DUMP SPECIFICATIONS" section of
+\fBamanda-match\fR(7)
+for more information\&.
+.PP
+Unless
+\fB\-p\fR
+is used, candidate backup images are extracted to files in the current directory named:
+hostname\&.diskname\&.datestamp\&.dumplevel
