One Way sync option

[bengene]

Is there a backup method to copy what is in Source to an Existing Target directory Without Deleting any files within the Target. The Source will have frequent updates but reusing the same file name (e.g. bengene.txt created June 1, 2015, modified June 2, 2015). I need the modified file information to update to the Target.

I tried Replication (Update), but it did not update. Target date stayed the same with the old information.

Any ideas?

I see my error in the configuration. I chose Replication Augment and changed it to correct setting Update. It works as it should.
