This is more of a reminder for myself so I don’t need to keep googling or looking at man when I need to look up the syntax.
Let’s assume you have two hard drives, ones called PHOTOS the other other PHOTOS_BACKUP. You can use the following command to sychronise photos (including removing all files that were deleted on PHOTOS to PHOTOS_BACKUP.) also ignoring backup files (.* files).
rsync -av --delete --exclude=".*" /Volumes/PHOTOS/ /Volumes PHOTOS_BACKUP
It’s nice to test this on a smaller folder first if you like. You should note the slash and lack of slash matters. To do a dry run try:
rsync -avn --delete --exclude=".*" /Volumes/PHOTOS/ /Volumes PHOTOS_BACKUP
or alternatively:
rsync -av --dry-run --delete --exclude=".*" /Volumes/PHOTOS/ /Volumes PHOTOS_BACKUP
Happy backups!
