Validating the destination file paths exchange 2016
This is critical to safe and reliable replication; if a server doesn’t know everything about a file, it can’t tell its partner about that file.
In DFSR, we often refer to this “initial build” and “initial sync” processing as “initial replication”.
These ensure that if you are allowing users to alter data on the upstream server while cloning is occurring, files are later reconciled on the downstream.
We recommend that you do not allow users to add, modify, or delete files on the source server as this makes cloning less effective, but we realize you live in the real world. You should not let users modify or access files on the downstream (destination) server until cloning completes end-to-end and replication is working.
I may be able to re-post even better numbers someday. You export the cloned database from the upstream server 4.
For instance, here I created exactly one million files and cloned that volume, using VMs running on a 3 year old test server. It’s awesome, like a grizzly bear that shoots lasers from its eyeballs. Let’s examine the mainline case of creating a new replication topology using DB cloning: 1. You preseed the files to the downstream (destination) server and copy in the exported clone DB files 5.
Export requires the output folder for the database and configuration XML file already exist.
It also requires that no replicated folders on that volume be in an initial build or initial sync phase of processing.
You add the downstream server to the replication group and RF membership, just like classic DFSR 7. Click Manage, and then click Add Roles and Features. Proceed to the Server Roles page, then select DFS Replication, leave the default option to install the Remote Server Administration Tools selected, and continue to the end.
We are talking about fundamental, state of the art performance improvements here, folks.
To steal from my previous post, let’s compare a test run with ~10 terabytes of data in a single volume comprising 14,000,000 preseeded files: I think we can actually do better than this – we found out recently that we’re having some CPU underperformance in our test hardware.
A replicated folder that contains tens of millions of preseeded files can take weeks to synchronize the databases, even with preseeding stopping the need to send the actual files.
Furthermore, there are times when you need to Any one of these requires re-running initial replication on at least one node.
