AMRECOVER(8)

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

Amanda configuration
    (default: DailySet1).

Host that runs the index daemon
    (default: astrolabei).

Host that runs the tape server daemon
    (default: astrolabei).

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:

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

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

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.

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 astrolabei, 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.

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.

Displays the extracting mode for Samba shares.

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

Display the name of the current backup working directory.

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.

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

Change the
    amrecover working directory to path.

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 the specified files or directories to the restore list.
    Each item may have shell style wildcards.

Add the specified files or directories to the restore list.
    Each item may be a regular expression.

Delete the specified files or directories from the restore list.
    Each item may have shell style wildcards.

Delete the specified files or directories from the restore list.
    Each item may be a regular expression.

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 the restore list.

Close the connection to the index server and exit.

Close the connection to the index server and exit.

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.

Display a brief list of these commands.

EXAMPLES
The following shows the recovery of an old syslog file.

        # cd /var/log
        # ls -l syslog.7
        syslog.7: No such file or directory

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

        # cd /var
        # (umask 077 ; mkdir .restore)
        # cd .restore
        # amrecover
        AMRECOVER Version 2.4.2. Contacting server on astrolabei ...
        ...
        amrecover> cd log
        /var/log
        amrecover> ls
        ...
        amrecover> add syslog.7
        Added /log/syslog.7
        amrecover> lpwd
        /var/.restore
        amrecover> extract
        Extracting files using tape drive /dev/null on host astrolabei
        ...
        amrecover> quit
        200 Good bye.
        # mv -i log/syslog.7 ../log/syslog.7-restored
        # cd ..
        # rm -fr .restore

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.

        # cd /var/log
        # amrecover
        AMRECOVER Version 2.4.2. Contacting server on astrolabei ...
        ...
        amrecover> ls
        ...
        amrecover> add syslog syslog.6 syslog.7
        Added /log/syslog
        Added /log/syslog.6
        Added /log/syslog.7
        amrecover> list

                /log/syslog.7
                /log/syslog.6
        TAPE DMP015 LEVEL 1 DATE 1997-12-09
                /log/syslog
        amrecover> quit

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.
