Oneway sync method

Is it possible to back up using the oneway sync method? If I change something in the source folder, no change is made to the destination folder?

Hello and welcome!

Duplicati is not a synchronization tool. The files in the destination are not in the same format as the source. Duplicati is a backup utility that supports deduplication, compression, retention, versioning, etc. It is one-way (source to destination only), but if you’re looking for a synchronization tool it’s not the right solution.
