If your sync is syncing a bunch of thumb.db files from windows cause someone opened the directory, you can easely remove it from the sync :


rsync -avhn --exclude 'Thumbs.db' source destination

note : I added -n for copy/paste mistakes 🙂

if you got plenty of file types/extensions you want ignored/excluded use :

rsync -avhn --exclude-from '/opt/exclude_rsync_list.txt' source destination

an example of this file could be :

.DS_Store
Thumbs.db

happy syncing.
