NAME
       amrecover - Amanda index database browser

SYNOPSIS
       amrecover [ [ -C ] config ] [ -s index-server ] [ -t tape-server ] [ -d
       tape-device ]

DESCRIPTION
       Amrecover browses the database of Amanda index files to determine which
       tapes contain files to recover.  Furthermore, it is able to recover
       files.

       In order to restore files in place, you must invoke amrecover from the
       root of the backed up filesystem, or use lcd to move into that
       directory, otherwise a directory tree that resembles the backed up
       filesystem will be created in the current directory.  See the examples
       below for details.

       See the amanda(8) man page for more details about Amanda.

OPTIONS
       [ -C ] config
              Amanda configuration (default: DailySet1).

       -s index-server
              Host that runs the index daemon (default: freebsd.org).

       -t tape-server
              Host that runs the tape server daemon (default: freebsd.org).

       -d tape-device
              Tape device to use on the tape server host (default: /dev/null).

COMMANDS
       Amrecover connects to the index server and then presents a command line
       prompt.  Usage is similar to an ftp client.  The GNU readline library
       is used to provide command line history and editing if it was built in
       to amrecover.

       The purpose of browsing the database is to build up a restore list of
       files to be extracted from the backup system.  The following commands
       are available:

       sethost hostname
              Specifies which host to look at backup files for (default: the
              local host).

       setdate YYYY-MM-DD
              Set the date (default: today).  File listing commands only
              return information on backup images for this day, for the day
              before with the next lower dump level, and so on, until the most
              recent level 0 backup on or before the specified date is
              encountered.

              For example, if:

                     1996-07-01 was a level 0 backup
                     1996-07-02 through 1996-07-05 were level 1 backups
                     1996-07-06 through 1997-07-08 were level 2 backups

              then if 1997-07-08 is the requested date, files from the
              following days would be used:

                     1997-07-08 (the latest level 2 backup)
                     1997-07-05 (the latest level 1 backup)
                     1997-07-01 (the latest level 0 backup)

              Only the most recent version of a file will be presented.

              The following abbreviated date specifications are accepted:

                     --MM-DD
                            dates in the current year

                     ---DD  dates in the current month of the current year

       setdisk diskname [ mountpoint ]
              Specifies which disk to consider (default: the disk holding the
              working directory where amrecover is started).  It can only be
              set after the host is set with sethost.  Diskname is the device
              name specified in the amanda.conf or disklist configuration
              file.  The disk must be local to the host.  If mountpoint is not
              specified, all pathnames will be relative to the (unknown) mount
              point instead of full pathnames.

       listdisk [diskdevice]
              List all diskname

       settape [[server]:][tapedev|default]
              Specifies the host to use as the tape server, and which of its
              tape devices to use.  If the server is omitted, but the colon is
              not, the server name reverts to freebsd.org, the configure-time
              default.  If the tape device is omitted, it remains unchanged.
              To use the default tape device selected by the tape server, the
              word default must be specified.  If no argument is specified, or
              the argument is an empty string, no changes occur, and the
              current settings are displayed.

              If you need to change the protocol (tape:, rait:, file:, null:)
              then you must specify the hostname.

                     settape freebsd.org:file:/file1

              You can change the tape device when amrecover ask you to load
              the tape:

                     Load tape DMP014 now
                     Continue? [Y/n/t]: t
                     Tape device: server2:/dev/nst2
                     Continue? [Y/n/t]: Y
                     Using tape /dev/nst2 from server server2.

       setmode mode
              Set the extraction mode for Samba shares.  If mode is smb,
              shares are sent to the Samba server to be restored back onto the
              PC.  If mode is tar, they are extracted on the local machine the
              same way tar volumes are extracted.

       mode   Displays the extracting mode for Samba shares.

       history
              Show the backup history of the current host and disk.  Dates,
              levels, tapes and file position on tape of each backup are
              displayed.

       pwd    Display the name of the current backup working directory.

       cd dir Change the backup working directory to dir.  If the mount point
              was specified with setdisk, this can be a full pathname or it
              can be relative to the current backup working directory.  If the
              mount point was not specified, paths are relative to the mount
              point if they start with "/", otherwise they are relative to the
              current backup working directory.  The dir can be a shell style
              wildcards.

       cdx dir
              Like the cd command but allow regular expression.

       lpwd   Display the amrecover working directory.  Files will be restored
              under this directory, relative to the backed up filesystem.

       lcd path
              Change the amrecover working directory to path.

       ls     List the contents of the current backup working directory.  See
              the description of the setdate command for how the view of the
              directory is built up.  The backup date is shown for each file.

       add item1 [ item2 ... ]
              Add the specified files or directories to the restore list.
              Each item may have shell style wildcards.

       addx item1 [ item2 ... ]
              Add the specified files or directories to the restore list.
              Each item may be a regular expression.

       delete item1 [ item2 ... ]
              Delete the specified files or directories from the restore list.
              Each item may have shell style wildcards.

       deletex item1 [ item2 ... ]
              Delete the specified files or directories from the restore list.
              Each item may be a regular expression.

       list [ file ]
              Display the contents of the restore list.  If a file name is
              specified, the restore list is written to that file.  This can
              be used to manually extract the files from the Amanda tapes with
              amrestore.

       clear  Clear the restore list.

       quit   Close the connection to the index server and exit.

       exit   Close the connection to the index server and exit.

       extract
              Start the extract sequence (see the examples below).  Make sure
              the local working directory is the root of the backed up
              filesystem, or another directory that will behave like that.
              Use lpwd to display the local working directory, and lcd to
              change it.

       help   Display a brief list of these commands.

       If you do not want to overwrite existing files, create a subdirectory
       to run amrecover from and then move the restored files afterward.

       If you need to run amrestore by hand instead of letting amrecover
       control it, use the list command after browsing to display the needed
       tapes.

       The history command shows each tape that has a backup of the current
       disk along with the date of the backup, the level, the tape label and
       the file position on the tape.  All active tapes are listed, not just
       back to the most recent full dump.

       Tape file position zero is a label.  The first backup image is in file
       position one.

ENVIRONMENT
       PAGER
