The default log size is 8GB. On the source server, run the following command and examine events , , , , , and On the destination server, run the following command to see the Storage Replica events that show creation of the partnership.
This event states the number of copied bytes and the time taken. Storage Replica dismounts the destination volumes and their drive letters or mount points. This is by design. Alternatively, the destination server group for the replica states the number of byte remaining to copy at all times, and can be queried through PowerShell. For example:. On the destination server, run the following command and examine events , , , , , and to understand the processing progress. There should be no warnings of errors in this sequence.
There will be many events; these indicate progress. Now you will manage and operate your server-to-server replicated infrastructure. You can perform all of the steps below on the nodes directly or from a remote management computer that contains the Windows Server Remote Server Administration Tools. To measure replication performance, use the Get-Counter cmdlet on both the source and destination nodes.
The counter names are:. Windows Server prevents role switching when the initial sync is ongoing, as it can lead to data loss if you attempt to switch before allowing initial replication to complete. Don't force switch directions until the initial sync is complete.
Check the event logs to see the direction of replication change and recovery mode occur, and then reconcile. Write IOs can then write to the storage owned by the new source server. Changing the replication direction will block write IOs on the previous source computer. Ensure you run the Remove-SRPartnership cmdlet on the current source of replication only, not on the destination server.
Run Remove-Group on both servers. For example, to remove all replication from two servers:. Many Microsoft customers deploy DFS Replication as a disaster recovery solution for unstructured user data like home folders and departmental shares. DFS Replication has shipped in Windows Server R2 and all later operating systems and operates on low bandwidth networks, which makes it attractive for high latency and low change environments with many nodes.
However, DFS Replication has notable limitations as a data replication solution:. Storage Replica has none of these limitations. It does, however, have several that might make it less interesting in some environments:. If these are not blocking factors, Storage Replica allows you to replace DFS Replication servers with this newer technology. The process is, at a high level:. Install Windows Server on two servers and configure your storage. This could mean upgrading an existing set of servers or cleanly installing.
Ensure that any data you want to replicate exists on one or more data volumes and not on the C: drive. You can also seed the data on the other server to save time, using a backup or file copies, as well as use thin provisioned storage. This issue occurs because DFSR considers the partial copy of the replicated file as invalid.
When a large file cannot be replicated in one session, DFSR saves a partial copy of the replicated file so that the replication process can continue from where it stopped. However, the replication connection is never opened long enough for the replication process to be completed. Therefore, large files cannot be replicated. A supported hotfix is available from Microsoft.
However, this hotfix is intended to correct only the problem that is described in this article. Apply this hotfix only to systems that are experiencing the problem described in this article. This hotfix might receive additional testing. Therefore, if you are not severely affected by this problem, we recommend that you wait for the next software update that contains this hotfix.
If the hotfix is available for download, there is a "Hotfix download available" section at the top of this Knowledge Base article. If this section does not appear, contact Microsoft Customer Service and Support to obtain the hotfix. Note If additional issues occur or if any troubleshooting is required, you might have to create a separate service request.
The usual support costs will apply to additional support questions and issues that do not qualify for this specific hotfix. Weekly and Monthly Sync : Compared with daily sync, weekly sync and monthly sync is less frequency. This ensure data security while use less disk space. Event Triggers : You can sync files at a specific event, including system shutdown , user logoff, system startup, and user logon.
Wake up computers and reconfigure operation after sync : Both features do a big favor when you want to sync files during off-peak hours, without human intervention. Sync the deletions in source directory to destination : By default, this Basic Sync feature does not sync deleted files automatically, but you can check this feature to ensure the deletions are synced together.
Step 5. Confirm the operations and click Start Sync to automatically sync folders between Windows Server Then, you can access data in the shared folder by its network path. And the latter version has a continuous improvement.
It uses a compression algorithm known as remote differential compression RDC to detect changes to the data in a file, then enables DFS Replication to replicate only the changed file blocks rather than the entire file. And it can resolve the administrative issue that XCopy and Robocopy cannot.
If not, this method will not work for you. In this case, you can go back to the first method. Step 1. Click Next in the Before You Begin page. Confirm this installation and click Install to ensure you want to install the selected roles, role services, or features.
Wait for a while, the installation process will be completed with words "Installation succeeded" displayed, and then click Close to close this page.
Start new replication.
