amrecover − Amanda index database browser

amrecover [−s index−server] [−t tape−server]
[−d tape−device] [−h hostname] [−o configoption...]
[−C config]



     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.

     Amrecover will read the amanda−client.conf file and the
config/amanda−client.conf file. If no configuration name is
supplied on the command line, Amrecover will try the
compiled−in default configuration ,usually DailySet1.

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



     Note

          The Default values are those set at compile−time.
     Use amrestore to recover client−encrypted or
     client−custom−compressed tapes.

     [ −C ] config
     Amanda configuration.

     −s index−server
     Host that runs the index daemon.

     −t tape−server
     Host that runs the tape server daemon.

     −d tape−device
     Tape device to use on the tape server host.

     −h hostname
     Hostname to begin restoring; defaults to the system's
     hostname.

     −o clientconfigoption
     See the "CONFIGURATION OVERRIDE" section in amanda(8).











                             ‐2‐




     The default auth is 'BSDTCP', you can set a different
auth in the amanda−client.conf file or by specifying the
'−oauth=bsd' command line argument.



     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−HH−MM[−SS] | YYYY−MM−DD
     Set the restore time (default: now). 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 the command setdate 1997−07−08−00 would yield
     files from the following days:

          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











                             ‐3‐


     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(5). 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.

     listhost [diskdevice]
     List all host

     listdisk [diskdevice]
     List all diskname

     storage [storage−name]*
     The name of the storage in order of preference, use
     'HOLDING' for the holding disk.

     listproperty
     List all property

     setproperty [append] [priority] name [value ...]
     Set the property name to the value value. The append
     keyword appends the value to the values already set for
     this property. Without value, the property is unset.
     The priority keyword is unused, it is present for ease
     of copy/paste from application definition.

     setdevice [[−h tape−server] tapedev]
     Specifies the host to use as the tape server, and which
     of its tape devices to use. If the server is omitted,
     the server name reverts to the configure−time default.
     If the tape device is omitted, the default is used.

     If you want amrecover to use your changer, the tapedev
     must be equal to the amrecover−changer setting on the
     server.

     Since device names contain colons, you must always
     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









                             ‐4‐


     back onto the PC. If mode is tar, they are extracted on
     the local machine the same way tar volumes are
     extracted.

     settranslate [on|off]
     Default: on. Translate escaped octal value ('\000') in
     the index file to their corespondig characters, it
     improve the interface if amrecover is run in the same
     charset as the filename. Set it to off if the charset
     of some filename is not compatible with the amrecover
     charset.

     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.









                             ‐5‐


     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.

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.

     PAGERThe ls and list commands will use $PAGER to
display the file lists. Defaults to more if PAGER is not
set.

     AMANDA_SERVER If set, $AMANDA_SERVER will be used as
index−server. The value will take precedence over the
compiled default, but will be overridden by the −s switch.

     AMANDA_TAPE_SERVER If set, $AMANDA_TAPE_SERVER will be
used as tape−server. The value will take precedence over the
compiled default, but will be overridden by the −t switch.
