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,
rather than the files that it references.
This prevents hierarchical restoration of complete subtrees
from the dump.
+.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.
+.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.
.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.
