Specifies the destination path of where to restore the
files. Without the -D option, the files are restored to
the current directory. When an argument follows the -f
option, it specifies the name of the storage device that
contains the saveset to be restored. The argument replaces
the default device /dev/tape/tape0_d1.
For rvrestore, the mandatory specification is nodename:device
to specify the remote machine name that
holds the saveset to be restored. There is no
default device. Displays usage help for the command.
Permits interactive restoration of files
read from a saveset. After reading directory
information from the saveset, the vrestore command
provides a shell-like interface that allows you to
select the files you want to restore. Some of the
following interactive commands require an arg
parameter that is a subdirectory or one or more
file names. The other interactive commands use
the current directory as default when the arg
parameter is not specified. Multiple file names can
be separated by spaces. Quotes (") can be used
around a file name that contains space(s). File
names containing quotes (") can be specified by
preceding the quote with a backslash (\). The
interactive commands are explained in the following
list: Adds the files in the saveset specified by
arg to the list of files to be restored. Files on
the list of files to be restored are prepended with
the * (asterisk) character when they are listed
with the ls interactive command. Changes the current
saveset directory to the directory specified
with the arg parameter. Deletes all files and
their subdirectories specified by the arg parameter
from the list of files to be restored.
An expedient way to select wanted files from any
directory in a saveset is to add the directory to
the list of files to be restored and then delete
the ones that are not wanted. Restores files, previously
added by using the add command, to the current
destination directory. Displays help information
for the interactive commands. Lists files in
the current saveset directory or the directory
specified with the arg parameter. Directory
entries are appended with a slash (/) character.
Entries that have been marked to be restored are
prepended with an asterisk (*) character. Writes
the path name of the current saveset directory to
the standard output device. Exits immediately,
even when the files on the list of files to be
restored have not been read. Escapes from the
shell, runs the system command, then returns to the
shell. Selects the -v modifier (see the -v
option). The name of each file restored from the
saveset is written to the standard output device.
Displays help information for the interactive commands.
Lists the entire saveset structure. Does
not preserve the owner, group, or modes of each
file from the device. Specifies the action to take
when a file already exists. The options are: Overwrites
existing files without any query. The
default is yes. Does not overwrite existing files.
Asks whether to overwrite an existing file. Prints
only error messages; does not print information
messages. Specifies that quota files should not be
restored. Lists the names and size (in bytes) of
all files contained in a saveset. Exception: the
sizes of any AdvFS quota files are not shown.
Writes the name of each file read from the storage
device to the standard output device. Without this
option the vrestore command does not notify you
about progress on reading from the storage device.
Displays the current version for the command.
Extracts a specific file or files from the saveset.
Use this command as an alternate to using the add
command in interactive mode. The -x option can
precede any other options, but the file... list
must be the last item on the command line.
For example, to restore the files file1 and file2
from the saveset on the default device,
/dev/tape/tape0_d1, to the /mnt directory, enter: #
vrestore -x -D /mnt file1 file2 Specifies the file
or files to restore when using the -x option. All
other options must precede any file names on the
command line.
The vrestore and rvrestore commands restore data from a
saveset previously archived by the vdump command or the
rvdump command. The data, which can be restored from a
file, a pipe (not applicable for the rvrestore command),
or a storage device (typically tape), is written to the
specified directory. The default storage device from
which files are read is /dev/tape/tape0_d1. You can use
the -f option to specify a different device or file. Tape
storage devices can contain more than one saveset. The
vrestore and rvrestore commands restore any associated
extended attributes, including ACLs, in the archive data.
See the proplist(4) and acl(4) reference pages.
The vrestore and rvrestore commands are the restore facility
for the AdvFS file system. However, the commands can
be used to restore UFS and NFS files that have been
archived by using the vdump or rvdump commands.
The default directory into which the files are restored is
the current directory. You can specify an alternate
directory by using the -D option.
Use the -t option to list the file names and sizes of the
files in a saveset without restoring any files.
When you are using the interactive shell and the AdvFS
user and group quota files are available in the saveset
for restoration, the file names used to refer to them will
be quota.user and quota.group, regardless of what the
quota files are named in either the backed up fileset or
in the destination fileset. Restoration of the quota
files does not change the names of the quota files in the
destination fileset. Use the -Q option if you do not want
to restore quota files.
If the destination fileset is AdvFS, and the saveset contains
AdvFS fileset quotas, the fileset quotas are
restored, even when they differ from the fileset quotas of
the destination fileset. By using the -Q option, -o no,
option or -o ask option, you can prevent this behavior.
The vdump and rvdump commands can write many savesets to a
tape. If you want to use the vrestore or the rvrestore
commands to restore a particular saveset, you must first
position the tape to the saveset by using the mt command
with the fsf option to move through your tape.
The source directory path from a vdump command line is
stored as a string in the header record of the saveset
produced. The vrestore command displays this string when
it restores the archived saveset. The string truncates at
128 characters. Several vrestore command options, including
-t, -l, -i, and -x, display the source directory path.
The command is the exact string from the vdump command:
it contains no relative pathname expansions or resolved
symbolic links.
For example, if a vdump command line contained instructions
to dump files from a directory named /usr/specs,
which was a symbolic link to a directory named
/tmp_mnt/pease1/usr/specs, the source directory string
displayed by the vrestore command would be /usr/specs:
The vdump command: % vdump -0 -f mydump /usr/specs
The vrestore command and string displayed: % vrestore -t
-f mydump vrestore: Date of the vdump save-set: "date"
>>> vrestore: Save-set source directory: /usr/specs
Files that were saved on a system running a pre-Version 5
operating system will be restored by a Version 5 operating
system in the same manner as they would have been restored
by a pre-Version 5 system. This means that any UFS sparse
files archived with the vdump command prior to Tru64 UNIX
Version 5.0 will be allocated disk space and filled with
zeros and any AdvFS striped sparse files archived with the
vdump command prior to Version 4.0D will be allocated disk
space and filled with zeros. If you save and restore your
sparse files under Version 5, they will remain sparse.
Note that an incremental dump only captures the files that
have changed, ignoring all others. This means that if you
perform a level 0 dump and a later incremental dump,
deleted files are not marked as gone (deleted). If you
then do a complete restore with a level 0 saveset and
incremental backups, the deleted files will be restored.
You must then delete these files individually.
You do not have to be the root user to use the vrestore
command, but you must have write access to the directory
to which you want to restore the files.
To run the rvrestore command, you must be able to execute
the rsh command from the remote node from which you want
to restore. See rsh(1) for server and client access rules.
Filesets that have been archived by using the vdump or
rvdump command must be restored by using the vrestore or
rvrestore command. The vdump and rvdump commands are not
interchangeable with the dump and rdump commands. Similarly,
the vrestore and rvrestore commands are not interchangeable
with the restore and rrestore commands.
A saveset stored on a block special device file containing
disk block 0 that has not had the disk label cleared will
contain an error and no files will be restored. See
vdump(8) for more information.
Only the root user can restore AdvFS quota files and fileset
quotas. A warning message is displayed when a nonroot
user attempts to use the vrestore command to restore
AdvFS quota files or fileset quotas. Use the -Q option to
prevent the restoration of quota files.
The vrestore command in operating system versions earlier
than Version 4.0 cannot be used to restore savesets produced
by the vdump command in Version 4.0 or higher systems.
The vrestore command in Tru64 UNIX Version 5.0 cannot
interactively restore quota files that have been saved by
the vdump command in Version 4.0D and earlier. However,
the command mode of the vrestore command in Tru64 UNIX
Version 5.0 can restore such quota files.
AdvFS quota files can be restored to either an AdvFS fileset
or a UFS file system, but UFS quota files cannot be
restored to an AdvFS fileset. If AdvFS quota files are to
be restored to a UFS file system, quotas must be enabled
on the UFS file system. Otherwise, the operation fails.
AdvFS fileset quotas cannot be restored to a UFS file system
because there is no UFS analog to AdvFS fileset quotas.
Attempting to use a vrestore or rvrestore to restore to a
base directory that has a default directory access control
list (ACL) or a default access ACL may cause unintended
ACLs to be created on the restored files and directories.
If ACLs are enabled on the system, check all ACLs after
using the vrestore or rvrestore command. View the documents
in SEE ALSO for more information about access control
lists (ACLs).
To restore a local archive produced by the vdump command
and mounted on the default storage device to the mnt
directory, enter a command similar to the following: %
vrestore -D /mnt To restore a remote archive produced by
the vdump or rvdump command and mounted on the default
storage device on machine node pease to the local mnt
directory, enter a command similar to the following: #
rvrestore -xf pease:/dev/tape/tape0 -D /mnt When the
restore saveset device is the character dash (-), the
vrestore command reads from standard input. Thus, the
vdump and vrestore commands can be used in a pipeline
expression to copy filesets. The following are typical
commands; they are equivalent: # vdump -0 -f - /usr | (cd
/mnt; vrestore -x -f -) # vdump -0f - /usr | vrestore -xf
- -D /mnt
The rvdump and rvrestore commands are unable to use
the dash (-) character. The output device must be
specified. To restore from a tape containing multiple
savesets you created with the vdump command,
use the mt fsf n command (forward space n savesets
or files) to locate the saveset to restore. The
following example will space forward to the third
saveset and then restore it: # mt fsf 2 # vrestore
-xf /dev/tape/tape0
