I have a 3TB external drive to move files to and from Client Locations. Most of the files don't get modified over time but when I do change files I use FreeFileSync to sync my laptop (with the drive connected) to the client drive and then on my home server with different FFS scripts. Additionally I use OSX Time Machine to backup my laptop. When the 3TB drive is connected it backs that up too. What I have noticed is that after I run the scripts for syncing with the two servers, my Time Machine wants to backup the entire drive and not just the files that have changed. This gets very time intensive with a drive this large. My question is: Does FFS modify the files in a manner that Time Machine sees ALL of the files as modified?
