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
[ -C ]config
Amanda configuration
(default: DailySet1).
-sindex-server
Host that runs the index daemon
(default: localhost).
-ttape-server
Host that runs the tape server daemon
(default: localhost).
-dtape-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 system.
The following commands are available:
sethosthostname
Specifies which host to look at backup files for
(default: the local host).
setdateYYYY-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
setdiskdiskname [ 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.
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 localhost, 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.
setmodemode
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.
cddir
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.
lpwd
Display the
amrecover
working directory.
Files will be restored under this directory,
relative to the backed up filesystem.
lcdpath
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.
additem1 [ item2 ... ]
Add the specified files or directories to the restore list.
Each item may have shell style wildcards.
addxitem1 [ item2 ... ]
Add the specified files or directories to the restore list.
Each item may be a regular expression.
deleteitem1 [ item2 ... ]
Delete the specified files or directories from the restore list.
Each item may have shell style wildcards.
deletexitem1 [ 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

If you need to run

control it,
use the

command after browsing to display the needed tapes.

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.
