DFS Replication Staging Quota

Question

_{Sunday, September 29, 2019 5:55 AM}

Grettings,

I am working on DFS implementation project. I have configured DFS replication groups to be on Drive Level. I noticed that by default there is 4 GB staging quota for each replicated folder.

Is this means if empty space on replicated drive become below 4 GB, replication will stop?

Hello Khaled,

The DFS Replication uses staging folders for each replicated folder, they act as a "cache" for new and changed files that are ready to be replicated from the source to the destination members.

The default is 4096MB (4GB), if the staging quota is too small, the DFS Replication might start using more of the CPU and disk resources and this might also lead to slow replication.

If the the quota is reached, the DFS Replication will start deleting old files from the staging folder to reduce the disk usage under the quota. The staging folder does not reserve hard disk space, and it only consumes as much disk space as is currently needed

Best regards,
Leon

Hi,
If a staging folder quota is too small, DFS Replication might consume additional CPU and disk resources, and replication might slow down or even stop.
and you can edit the quota size or location of the staging folder ,if the replicated folder is larger. For more information you can refer to the following link:
