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

  Note
The listed defaults map to the values you ran the configure-script with.

[ -C ] config
    AMANDA configuration (default: daily).

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

-t tape-server
    Host that runs the tape server daemon (default: 192.168.0.10).

-d tape-device
    Tape device to use on the tape server host (default: /dev/nst0).

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 192.168.0.10, 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 want amrecover to use your changer, the tapedev must be equal to the amrecover_changer setting on the server. If you need to change the protocol (tape:, rait:, file:, null:) then you must specify the hostname.
    settape 192.168.0.10: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.

EXAMPLES

The following shows the recovery of an old syslog file.
# cd /var/log
# ls -l syslog.7

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

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

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.
