rsync - Apr 2002 - why --delete dosen't work in my script?

Hi,

In my backup script I have noticed nothing gets deleted on the remote
end even though I have --delete and --delete-excluded. Did I miss
anything obvious here?

rsync -azC
	-e ssh
	--relative
	--one-file-system
	--sparse
	--numeric-ids
	--vP
	$IGNORE ## a long list of --exclude patterns
	--delete
	--delete-excluded
	--bwlimit=0
	--backup
	--suffix=''
	--backup-dir=$REMOTE_ROOT/$BACKUP_HOST/$TODAY
	/{etc,home,var/lib,var/cvs,usr/local}
	backup.host.com:$REMOTE_ROOT/$BACKUP_HOST/current

Also, is there any way at all to make --exclude patterns
case-insensitive? Or do I have to write '*.[eE][xX][eE]' etc.?


Thanks in advance, cheers,

Not sure if this applies to you, but...

One thing I noticed about trying to use --delete in combination with -b
--backup-dir is that files do not get deleted if there is already another
hard link to them on the target side.  As I understand it, this is not so
much a bug in rsync as it is a somewhat non-intuitive POSIX behavior in my
operating system (Linux).

Basically, if it can, backup just renames the file instead of copying it.
But on my system, if a and b are both hard links to the same inode,

mv a b

does *not* unlink a!  It has no effect, in fact.

My solution was to make two rsync passes, the first with -b --backup-dir
but no --delete, the second without -b --backup-dir but with --delete.
At some point, though, maybe we should patch rsync to make it do the
intuitive thing in this case.

Does anyone else have experience with this?

Regards,
Mike
