AMRECOVER(8) AMANDA INDEX AMRECOVER(8)NAMEamrecover - Amanda index database browser
SYNOPSISamrecover [ [ -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. Further
more, it is able to recover files.
In order to restore files in place, you must invoke amre
cover 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 cre
ated in the current directory. See the examples below for
details.
See the amanda(8) man page for more details about Amanda.
OPTIONS
[ -C ] config
Amanda configuration (default: DailySet1).
-s index-server
Host that runs the index daemon (default: amanda-
server).
-t tape-server
Host that runs the tape server daemon (default:
amanda-server).
-d tape-device
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 sys
tem. 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 com
mands only return information on backup images for

AMRECOVER(8) AMANDA INDEX AMRECOVER(8)
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 encoun
tered.
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 pre
sented.
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 speci
fied 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.
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 amanda-server, 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 speci
fied. If no argument is specified, or the argument
is an empty string, no changes occur, and the cur
rent settings are displayed.

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 cur
rent 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.
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 com
mand 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 wild
cards.
addx item1 [ item2 ... ]
Add the specified files or directories to the
restore list. Each item may be a regular expres
sion.
delete item1 [ item2 ... ]
Delete the specified files or directories from the
restore list. Each item may have shell style wild
cards.
deletex item1 [ item2 ... ]
Delete the specified files or directories from the

restore list. Each item may be a regular expres
sion.
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.
