I am using the sync command for cloning my files to the other side (local to sftp) It works great and I like it a lot, more than Rsync.
Is it possible to run sync for real only if there is acertain file in the source folder? The reason is that I want to put this in a cron job and I want to make sure that I am not wiping out the target. These are mounted bacups so they always have backup conf files there.
