It first changes its working directory to the root of the filesystem
that was dumped and compares the tape with the files in its new
current directory.
+See also the
+.Fl L
+flag described below.
.It Fl i
This mode allows interactive restoration of files from a dump.
After reading in the directory information from the dump,
.Nm restore
to print out information about each file as it is extracted.
.El
+.It Fl P Ar file
+.Nm Restore
+creates a new Quick File Access file
+.Ar file
+from an existing dump file without restoring its contents.
.It Fl R
.Nm Restore
requests a particular tape of a multi-volume set on which to restart
.Pp
The following additional options may be specified:
.Bl -tag -width Ds
+.It Fl a
+In
+.Fl i
+or
+.Fl x
+mode,
+.Nm restore
+does ask the user for the volume number on which the files to
+be extracted are supposed to be (in order to minimise the time
+be reading only the interesting volumes). The
+.Fl a
+option disables this behaviour and reads all the volumes starting
+with 1. This option is useful when the operator does not know on which
+volume the files to be extracted are and/or when he prefers the
+longer unattended mode rather than the shorter interactive mode.
+.It Fl A Ar archive_file
+Read the table of contents from
+.Ar archive_file
+instead of the media. This option can be used in combination with the
+.Fl t,
+.Fl i,
+or
+.Fl x
+options, making it possible to check whether files are on the media
+without having to mount the media.
.It Fl b Ar blocksize
The number of kilobytes per dump record.
If the
.Nm
reverts back to the real user ID and the real group ID before
running the script.
-.It Fl k
-Use Kerberos authentication when contacting the remote tape server.
-(Only available if this options was enabled when
-.Nm restore
-was compiled.)
-.Pp
.It Fl h
Extract the actual directory,
rather than the files that it references.
This prevents hierarchical restoration of complete subtrees
from the dump.
+.It Fl k
+Use Kerberos authentication when contacting the remote tape server.
+(Only available if this options was enabled when
+.Nm restore
+was compiled.)
+.It Fl l
+When doing remote restores, assume the remote file is a
+regular file (instead of a tape device). If you're restoring
+a remote compressed file, you will need to specify this
+option or
+.Nm restore
+will fail to access it correctly.
+.It Fl L Ar limit
+The
+.Fl L
+flag allows the user to specify a maximal number of miscompares
+when using
+.Nm restore
+with the
+.Fl C
+option to check the backup. If this limit is reached,
+.Nm restore
+will abort with an error message. A value of 0 (the default value)
+disables the check.
.It Fl m
Extract by inode numbers rather than by file name.
This is useful if only a few files are being extracted,
.Fl N
flag causes
.Nm
-to only print file names. Files are not extracted.
+to perform a full execution as requested by one of
+.Fl i,
+.Fl R,
+.Fl r,
+.Fl t
+or
+.Fl x
+command without actually writing any file on disk.
.It Fl Q Ar file
Use the file
.Ar file
in order to read tape position as stored using the dump Quick File
-Access mode.
+Access mode, in one of
+.Fl i,
+.Fl x
+or
+.Fl t
+mode.
+.Pp
+It is recommended to set up the st driver to return logical tape
+positions rather than physical before calling dump/restore with
+parameter Q. Since not all tape devices support physical tape
+positions those tape devices return an error during dump/restore when
+the st driver is set to the default physical setting.
+Please see the st man page, option MTSETDRVBUFFER, or the mt man
+page, on how to set the driver to return logical tape positions.
+.Pp
+Before calling restore with parameter Q, always make sure the st
+driver is set to return the same type of tape position used during the
+call to dump. Otherwise restore may be confused.
+.Pp
+This option can be used when restoring from local or remote tapes
+(see above) or from local or remote files.
.It Fl s Ar fileno
Read from the specified
.Ar fileno
(verbose)
flag causes it to type the name of each file it treats
preceded by its file type.
+.It Fl V
+Enables reading multi-volume non-tape mediums like CDROMs.
.It Fl X Ar filelist
Read list of files to be listed or extracted from the text file
.Ar filelist
If this variable is not set,
.Xr rcmd 3
will be used, but only root will be able to do a network restore.
