DataSync synchronization

Question

"I'm interested in copying a substantial volume of data between two AWS EFS instances within the same region. I'd like to determine if DataSync offers the capability to perform a differential synchronization. Specifically, I want to run a DataSync task on a Monday to complete the initial transfer and then run it again on a subsequent Friday, ensuring that the Friday synchronization only identifies and copies new items , and if something changed to also copy the change to the destination."

Accepted Answer

Hello.

I think it is possible to perform differential synchronization by using "CHANGED" in "TransferMode".

In the management console, select "Transfer only data that has changed".
