amrecover (8)

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).

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

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.

The following shows the recovery of an old syslog file.

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.

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.
