NAME
amrecover - Amanda index database browserSYNOPSIS
amrecover
[-s index-server] [-t tape-server]
[-d tape-device] [-h hostname]
[-o configoption...] [-C config]
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. 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.OPTIONS
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).
AUTH
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.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 hostnameSpecifies 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:
then the command setdate 1997-07-08-00 would yield files from the
following days:
Only the most recent version of a file will be presented.
The following abbreviated date specifications are accepted:
--MM-DD
setdisk diskname [mountpoint]
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
1997-07-08 (the latest level 2 backup) 1997-07-05 (the latest level 1 backup) 1997-07-01 (the latest level 0 backup)
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(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.
setmode mode
settape 192.168.0.10:file:/file1You 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.
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.
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.
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.

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
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.SEE ALSO
