I'm trying to set up a backup routine that will copy files like-for-like. I've set up Rsync in a Mac Automator routine to sync a windows formatted removable drive attached to my MacBook to a NAS drive on my wifi network.
I'm using 'rsync -va', the source is 37GB - I left the routine running for around 12 hours and when I checked the destination folder it was over 80GB in size, I stopped the routine at this point.
If I run 'rsync -avnc' to check if the folders are the same, I get a full list of the sources contents - I'm assuming that this means that the files on the destination are not the same?
I'm happy to delete the destination folder and start again as I'm trying to perfect the routine so I can use Automator to easily do what I need it to do - What do I need to change in Rsync to get exact copies?
