Re: Differential backup based on catalogue file

Hello Tong,

there is an easy way to know why dar saved a file for differential
backup, it is to use the archive of reference and make a diff (dar -d)
against the fileystem you want to backup. For each file that differs
between archive and fileystem, dar will output what causes the difference.

In the hope it will help you understand,
Regards,
Denis.
