The size of the Conflict and Deleted folder is near the quota limit for the replicated folder '{0}' that belongs to replication group '{1}'.


If the Conflict and Deleted folder runs out of space, DFS Replication will remove older conflicting or deleted files to free up disk space, which might temporarily decrease replication performance.

If a staging folder quota is configured to be too small, DFS Replication might consume additional CPU and disk resources to regenerate the staged files. Replication might also slow down because the lack of staging space can effectively limit the number of concurrent transfers with partners. Increasing the size of the staging folder and the Conflict and Deleted folder can increase replication performance and the number of recoverable conflicting and deleted files.


Delete files from the Conflict and Deleted folder, or increase the quota of the Conflict and Deleted folder for the appropriate replicated folder(s).

To increase the quota size, see Edit the Quota Size of the Staging Folder and Conflict and Deleted Folder (http://go.microsoft.com/fwlink/?LinkId=186944).
