Ok thanks, this sounds reasonable.
Well, I changed '-a' to '-rlpgoD' (according to the man page, it maps to
'-rlptgoD'). But now it's worse.... each call of rsync copies all the
files from source to new.
/opt/rsync/bin/rsync -crlpgoDv
--link-dest=/home/user/backup/old
/home/user/source
/home/user/backup/new
Do you understand what I want to do? Is there anything wrong with the
above command (or my idea of rsync and --checksum)?
Thanks for your help,
Andreas
