command
SYNOPSIS
restore
key
args
...
DESCRIPTION
The restore restores files from backup tapes created with the dump (see dump)
command. A full backup of a file system may be restored and subsequent incre-
mental backups layered on top of it. The actions of restore are controlled by the
given
key
, which is a string of characters containing at most one function letter
and possibly one or more function modifiers.
The function portion of the key is specified by one of the following letters:
r Restores (rebuilds a file system or subtree). The target subtree should be
made pristine by removing it from a client of the server or, if the entire file
system or all subtrees of the file system are to be restored, by booting from
floppy disk and selecting the Install new file system. option, before start-
ing the restoration of the initial level 0 backup. If the level 0 restores
successfully, the r key may be used to restore any necessary incremental
backups on top of the level 0.
Note that restore r will restore
all
files from the dump tape(s).
An example:
restore rf rst0a
Note that restore leaves a file restore_symboltable in the directory that
was dumped to pass information between incremental restore passes. This
file should be removed when the last incremental has been restored.
Rrestore requests a particular tape of a multi-volume set on which to restart a
full restore (see the r key above). This is useful if the restore has been
interrupted.
t Lists the names of the specified files if they occur on the backup. If no file
argument is given, then the root directory is listed, which results in the entire
content of the backup being listed.
x Extracts the named files. If a named file matches a directory whose contents
were backed up, the directory is recursively extracted. The owner, modifica-
tion time, and mode are restored. If no
filename
argument is specified, the
backup root directory is extracted. This results in the entire backup being
restored.
The following characters may be used in addition to the letter that selects the
function desired.
