DFS namespace and replication health checks
Overview
DFS-N presents unified UNC paths; DFS-R (or Storage Replica) keeps folders convergent. Stuck replication hides split-brain data loss.
Weekly automation
dfsrdiag backlog / PowerShell Get-DfsrState; alert on files stuck > threshold minutes.
Common breaks
- DNS pointing clients to dormant namespace server.
- Schedule bandwidth throttling too aggressive during business hours—withheld backlog bursts overnight fail backup window overlap.
- Antivirus locking staging files—exclusions per Microsoft guidance.
DR
Document authoritative restore direction—never guess during DR; wrong primary wipes good copy.
Upgrades
Schema and DFSR version alignment before domain functional level jumps; test lab first.
