Comparison settings: time shift

[leoleo]

Hello everyone.

I have 2 external hard disks for backup.

I usually do a first backup on one of them and then using FreeFileSync I backup that disk to another disk.

The problem is that when I compare a certain folder the results are showing me all the files of both disks because there is a difference of the 'date added'. So I get a message like 'the file on the left side is older' for all my files and I can't just copy the files that I haven't already backed up.
Needless to say that I usually compare very large folders therefore using the 'file content' on comparison settings takes time.
Moreover I did not have that problem on Windows OS. Now I am using FFSyng on Mac OSX.

All I want is to compare my 2 disks and if a file does not exist on one them then copy it (content-wise and not time-wise).

Any ideas? Possibly the 'file content' setting is the solution but I just wanted to check if I could use FFSync on OSX just like Windows.

Thank you!

You can make FFS ignore a given modification time shift:
