Use keepuptodate both ways?

We have a setup where we want both local and remote location to be mirrored at all times.

Keepuptodate is working fine but only seems to update from local to remote location.

Can it be changed to work both ways?

Alternatively i will use synchronize both and put it in a tasked schedule.

Thank you in advance

Yes, use the two-way synchronization, as you have suggested yourself.
