Recovery Guide

Reduce AD replication backlog before tombstone lifetime turns delay into data loss risk.

Use this guide when replication has been unhealthy long enough that simple “wait it out” thinking becomes dangerous. The goal is to reduce backlog safely while keeping the directory clean enough for recovery.

Situation

Backlog is a risk multiplier, not just a health warning.

The longer replication stays broken, the more likely stale objects, policy drift, and risky cleanup decisions become. Recovery needs to prioritize transport, naming, authentication, and partner health before drastic actions.

What To Verify

Know whether you are dealing with delay, blockage, or corruption risk.

  • Which naming contexts are backlogged and for how long.
  • Whether the cause is path failure, auth failure, or a broken partner state.
  • How close the environment is to cleanup or tombstone-related risk thresholds.
  • Whether rebuilt or decommissioned DC history is contributing stale metadata.
Working Sequence

Recover flow, then compress backlog.

  • Restore the path and replication prerequisites before attempting aggressive sync operations.
  • Prioritize healthy hub-to-spoke paths that reduce the widest backlog first.
  • Track progress per naming context, not just per server.
  • Escalate to metadata cleanup or rebuild only when the broken partner cannot be safely restored.
