The tar output file also stores the file names (and permissions) you give it so it knows how to restore them, just as Winzip and other tools do. If you give it a name starting with /, then that forms the name when you restore.
I do wonder what the purpose of this is. Are you planning to use it for recovering if a disk/server/site is lost? The problem you may have is getting something running so that you can execute the restore and if it's dissimilar hardware it still may not work.
What is the requirement for this backup, i.e. what are you planning to restore to?
Kind regards,
Robin
I was asking the question only for my knowledge only..i like to dig deep and investigate.
I usually use tar to backup my Debian Lenny server..but that day I was surprised to see the syntax with the dot..I thought it was a typing error. I tried omitting the dot...it gives an error.
The following is the command I use for backup:
The restore was done on a PC, I boot with a live CD, wipe everything on the /
, then UNTAR everything there.
For the PC to successfully boot:
1. MBR/GRUB must be properly configured
2. udev > persistent rules - must remove the MAC addresses
3. in /boot/grub directory necessary changes needs to be done if you are changing from a raid 1 to a non-raid configuration.
The restore was a good experience for me and worked without any issues

amsamba
AMSAMBA(8) System Administration Commands AMSAMBA(8)NAME
amsamba - Amanda Application to interface with smbclient
DESCRIPTION
Amsamba is an Amanda Application API script. It should not be run by users directly. It uses smbclient to backup and restore data.
The diskdevice in the disklist (DLE) must have the form '//CIFSHOST/SHARE/SUBDIR' where CIFSHOST is the CIFS host containing the data to be
backed up, SHARE is the share to connect, and subdir is the subdirectory to backup. '/subdir' can be ommited, in which case the complete
share is archived.
Unlike most applications, amsamba backs up and restores data located on a different system from that where amsamba itself runs. The host
containing the data is the CIFS host. In practice, amsamba is usually run on the same system as the Amanda server, with a DLE like
localhost "//CIFSHOST/SHARENAME" amsamba-dumptype
Include or exclude can be used, but not both. The path for 'exclude list' or 'include list' must be absolute path on the CIFS host. The
estimate calculates the complete size of the share, without regard for include or exclude directives. It will be larger than the actual
dump if you use include or exclude. Using 'estimate server' in the dumptype could give better estimate.
PROPERTIES
This section lists the properties that control amsamba's functionality. See amanda-applications(7) for information on application
properties and how they are configured.
SMBCLIENT-PATH
The path to the smbclient binary. The default is set when Amanda is built by the --with-smbclient configure option.
GNUTAR-PATH
The path to the gnutar binary. The default is set when Amanda is built by the --with-gnutar configure option. gnutar is used to create
the index.
AMANDAPASS
Location of the amandapass file, defaulting to "$CONFIG_DIR/amandapass". Relative pathnames are relative to the configuration
directory, "$CONFIG_DIR/<config>". Note that this file is located on the client, not on the server. The format of the file is as
follow:
Sharename User%Password Domain
Sharename is '//HOST/SHARE' without the SUBDIR. Sharename can be quoted, it can be '*' to match all share, it can be '//pc-host/*' to
match all share on pc-host. User is the username use to connect to the share. Password is the password use to connect to the share.
'%Password' is optional if the user can connect to the share without password. 'User%Password' is optional, the user 'guest' without
password is use to connect to the share. Domain is optional. Example:
//another-pc/share otheruser%otherpw domain
//another-pc/share otheruser%otherpw
//another-pc/share myuser mydomain
//another-pc/share myuser
//another-pc/share
ALLOW-ANONYMOUS
This username without password is used to connect to the share if no matching entry is found in the amandapass file.
DIRECTORY
For restore command only, the data is recoved in that directory. Must be a unix path for "tar" RECOVER-MODE or a smb path for "smb"
recover-MODE.
RECOVER-MODE
"tar" or "smb", default to "tar". If "tar", the data is recovered on the local machine, If "smb", the data is recovered on the smb
client machine.
INCLUDE AND EXCLUDE LISTS
This application supplies exclude lists via the smbclient -TX option. Normal shell-style wildcard expressions, using * and ?, are not
supported. All expressions are matched only from the base directory of the DLE. Expressions that match a directory may have a leading or
trailing "/". Example expressions:
./temp-files # exclude top-level dir "temp-files" entirely
./temp-files/ # same
/temp-files # same
temp-files # same
./temp-files/* # BAD: does nothing
*.iso # BAD: does nothing
proxy/local/cache # exclude "cache" in dir "proxy/local"
Include lists are supported only if excludes are not given. They are handled via the smbclient -TI option. Include matching is identical to
the exclude matching described above.
EXAMPLE
define application app_amsamba {
property "SMBCLIENT-PATH" "/usr/bin/smbclient"
property "GNUTAR-PATH" "/bin/tar"
property "AMANDAPASS" /etc/amandapass"
property "ALLOW-ANONYMOUS" "guest"
}
