Dear experts,

I have an issue at one of our customers sites.
My customer has two locations with DFS configured. (NOT DFSR).
DFS is configured a backup purposes.
The HQ sents its data to the target location everyday at 20:00 PM
An application has created a lot of data at HQ. After this events the DFRS service stopped with event warning 5014.
After 6 of these errors the DFRS stopped with error 5002. which states that the DFRS stopped.

After these events the unexpected happened.
The targeted location started to replicate files back! at the 26 jan the customer detected old version files on the current shares.

Not smart to configure this as DFS instead of DFSR.

But is there a way to recover these data?

I have no idea where to begin or how to approuch this issue.

Did you happen to turn on volume shadow on those drives that the DFS is pointing to?  If you did then that's your only recourse.

I don't understand how it is replicating if you say you are not using DFSR?

what i mean convergint, is that is was configured 1 way replication. not two way.
I think by accident en external consultant configured two way replication.

clearly in the logs i could see there were conflicts in files. and that DFS is calculating the best file. the other file was placed in the conflict and deleted folder.
DFS has removed a lot of files. with this comparisson proces. and the quota of the conflicts and deleted folder was set tot 660 MB. which means. the rest is gone. or not? is there a way to recover this data?

Sadly no VSS is configured on the disks...
Without backups and VSS I do not believe there is any way now as the files have basically been overwritten.
