How to synchronize local harddrive directory (don't keep old snapshots)?

Hello,

I am a Kopia newbie.

I want to use Kopia to synchronize a directory on my local hard drive with a cloud storage. I.e. only ONE version of the latest snapshot should be available on the cloud (no other old snapshots should be archived).

How to set up the retention policy of the snapshot for this simple case? Do all retention fields have to be filled with number zero?

Thank you in advance and kind regards,
Bernd
