[LUNI] Incremental Tar

[Matt T.]

Hi, 

	I was curious if anyone had experience with tar incremental backups?
Basically the information im looking for is what/how does GNU tar
define what and how an incremental backup is done? ie.. Are only modified
files updated in the tar archive? or are the modified files appended to the 
current archive?

Is cpio a better alternative?..

Furthermore I was curious as to what optioni is better the -g(new) or -G(old)
and what the *actual difference is between the two?
