The item at the end says what to back up. The dot refers to the current directory. It could be a full path so somewhere if that suits better, however that will mean that the files can only be restored to the named location. Using a relative path name to where you are (or just a dot) means that you can restore files to the same place relative to where you are when you do the restore.
As an alternate to copying, you could do something like this:-
if you just did this:-
.... then a restore would always write to /home/RBATTE1 which may be undesirable.
It's a bit of a crude description, but I hope you get the idea.

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?

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

Every day we back up all files on our system that are older than 7 days, so effectively we do a day's worth at a time.
The way we do this is to issue a find command using mtime +7 - we then loop round and for each result we issue a MV to move the file to a newly created directory. We then TAR the... (20 Replies)
