Syncing large datasets between 3 locations, long check times

Joshua · Joined: 26 Dec 2019 Posts: 3

Hello. I am currently using ViceVersa 2.5 to sync a very large dataset between 3 sites.
I have ViceVersa installed at Site A, and Site C. Site A has a synchronize job running between Site A and Site B, and Site C has a synchronize job running between Site C and Site B. This effectively allows this dataset to synchronize between all 3 sites. Changes to the dataset are made at all 3 sites.

The problem is this dataset is very large (around 900GB), and continually growing, and is taking an excessive amount of time to perform the target check (around 2 - 4 hours). The actual data transfer does not take very long in comparison to the target check. The internet speed at all 3 locations is good.

I've looked into the no Rescan options, but this does not some appropriate for my setup.

Is there anything I can do to make this setup run better? Does TGMRN offer any other products that would be able to do this type of synchronization any faster?

Hi, did you try setting up the VVEngine add-on to work in real-time? Please see:

Hi, yes, you would need to install VVEngine and ViceVersa on all locations to detect local changes and send the changes to the other sites in real-time.

Same setup as in this document:

I just wanted to update this thread that setting up VVEngine (and a third instance of ViceVersa at Site B) seems to be working pretty well.

I have considered setting up another set of jobs running one way real time syncs directly from Site A to Site C (and Site C to Site A), but I'm not sure how much this would rock the boat.
