NAME
amrecover - Amanda index database browser
SYNOPSIS
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
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).
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 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
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
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 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.
EXAMPLES
The following shows the recovery of an old syslog file.
# cd /var/log
# ls -l syslog.7

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 The 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.
