rsync compares all files again and again
Hi,
we do a 1:1 backup from our main raid to a backup raid every night with
rsync -a --delete /mnt/raid1/ /mnt/raid2
rsync is 3.09, filesystems are ext3, OS is SLES 11 SP1.
The rsync process takes several hours, even if no file has changed at all.
Using -vv I see that rsync compares all files every time and that takes
long for some hundreds of millions of small files.
Can I tell rsync it
