Synchronise or Consolidate? Two servers over WAN

Hi

I have tested VV and find that while it sounds like Synchronise is what I should be using, the consolidate option seems to work the same and is not as sensitive. Synchronise gives errors that I have no idea how to resolve, while consolidate works on the exact same profile.

What I need is something that can be configured to automatically synchronise the files on one server with another, in both directions.

Scenario: 3 different servers
- Server A: Application. creates and uses files on server FV1.
- Server FV1: Server on the same LAN as server A. Contains instrument files that are created by application and files received from server FV2
- Server FV2: Server on WAN. Contains instrument file volume. Instruments on same LAN as FV2 create files on FV2 and read files received from server FV1.

The application system only connects with server FV1 (it may not directly interact with instrument files on FV2 over the WAN)

The synchronisation tool must be able to:
- monitor server FV1 for new files and copy new or updated files to server FV2
- monitor server FV2 for new files and copy new or updated files to server FV1

Rules:
1. 'Synchronisation' must occur as a result of a file being created or updated, not according to a time based schedule.
2. The file volumes on FV1 and FV2 are configured with sub-folders that are 'directionally' consistent. All files in a respective sub-folder will all have been created by the application on A. All files in another sub-folder will have been created by an instrument connected to FV2.
3. New and updated files must be copied.
4. Old files with the same name as new files from either FV1 or FV2 can be overwritten. i.e. the data on FV1 & FV2 must effectively be kept identical.

Hello, the only difference between synchronization and consolidation is how deleted files are treated. With synchronization, a file that was deleted from source will be deleted from target and viceversa. With consolidation if a file is deleted from source is copied back from target and viceversa.

Ok, so it seems that I can use consolidation rather than synchronisation?
Synchronisation is very sensitive to certain file change conditions (source & target file change) and then it just stops. If source & target change with consolidation then the newest file is used - this is ok.

In the realtime.pdf the following is stated:

Hi, the document focuses only on sync and backup in real time, however consolidation can be used too. thanks

Thank you for the support and excellent product.

Real time file update/create/delete consolidation is working between two servers across the WAN.

I have set up ViceVersa on the one server and VV engine & Windows services on the same server to moniter and run profiles that send and receive files from both servers.
What will the total licensing requirement be? (VSS support is required)

Hi, it will require 2 ViceVersa PRO server licenses to cover the two servers and 1 VVEngine license if VVEngine is installed only on the one server. thanks
