Inno,
If files are all different, and you modify 10GB every day keeping the 600
total, I think (pretty sure) that yes, on the 4th you'll have the original
600GB plus the 40GB differences.
That with incrementals.
With fulls every day, you'll have just 600GB every day, total on the pool
(we are not minding about compression), after the cleanup.
(Really hope Les don't mind me saying what he said with other words. I'm
taking the chance to think loud with Inno.)
But fulls are slower, even with rsync. That also means that with tar or
samba are even slower. You know why?
I'm going to go through http://www.samba.org/rsync/documentation.html.
Something scared me first time, and I didn't return.
Thanks, Les
Regards
Luis
