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

backintime
backintime(1) USER COMMANDS backintime(1)NAME
backintime - a simple backup tool for Linux.
This is command line tool. The graphical tools are: backintime-gnome and backintime-kde4.
SYNOPSIS
backintime [ --backup | --backup-job | --snapshots-path | --snapshots-list | --snapshots-list-path | --last-snapshot | --last-snapshot-path
| --help | --version | --license ]
DESCRIPTION
Back In Time is a simple backup tool for Linux. The backup is done by taking snapshots of a specified set of folders.
All you have to do is configure: where to save snapshots, what folders to backup. You can also specify a backup schedule: disabled, every
5 minutes, every 10 minutes, every hour, every day, every week, every month. To configure it use one of the graphical interfaces available
(backintime-gnome or backintime-kde4).
It acts as a 'user mode' backup tool. This means that you can backup/restore only folders you have write access to (actually you can backup
read-only folders, but you can't restore them).
If you want to run it as root you need to use 'su'.
A new snapshot is created only if something changed since the last snapshot (if any).
A snapshot contains all the files from the selected folders (except for exclude patterns). In order to reduce disk space it use hard-links
(if possible) between snapshots for unchanged files. This way a file of 10Mb, unchanged for 10 snapshots, will use only 10Mb on the disk.
When you restore a file 'A', if it already exists on the file system it will be renamed to 'A.backup.currentdate'.
For automatic backup it use 'cron' so there is no need for a daemon, but 'cron' must be running.
user-callback
During backup process the application can call a user callback at different steps. This callback is "$XDG_CONFIG_HOME/backintime/user-
callback" (by default $XDG_CONFIG_HOME is ~/.config).
The first argument is the progile id (1=Main Profile, ...).
The second argument is the progile name.
The third argument is the reason:
1 Backup process begins.
2 Backup process ends.
3 A new snapshot was taken. The extra arguments are snapshot ID and snapshot path.
4 There was an error. The second argument is the error code.
Error codes:
1 The application is not configured.
2 A "take snapshot" process is already running.
3 Can't find snapshots folder (is it on a removable drive ?).
4 A snapshot for "now" already exist.
