  1. Active Directory Disaster Recovery

  2. Domain Controllers • No PDC, BDC • All DCs are equal • Some are more equal than others (operations masters) • Can demote DC to member server • Can change its name this way • Can promote member server to DC

  3. Active Directory Files • Default location %systemroot%\NTDS • Ntds.dit — Active Directory database • Edb*.log — Transaction log files • Edb.chk — Checkpoint file to check data not yet written to database • Res*.log — Reserved transaction log files (10MB each to reserve space in case disk fills up)

  4. Garbage Collection • Runs periodically • Deletes tombstoned objects • Defragments database

  5. System State • Includes everything that AD depends on, not just database files • Database and log files • SYSVOL shared folder • Registry • System startup files • Class registration database • Certificate Services database

  6. Backing up Active Directory • Accessories/System Tools/Backup • Allows backup of system state • TSM (to HFS) • Backs up system object • Includes Active Directory • Third party • For complete backup, AD on all domain controllers must be backed up

  7. Non-Authoritative Restore • Restores Active Directory to state before backup was made • Updates from other DCs are made via replication as usual

  8. Authoritative Restore • Possible to mark part of Active Directory as authoritative on server where you are restoring it • Authoritative parts replicated to other DCs • E.g. to restore deleted objects • Only part of database can be restored authoritatively • Can select subset to be restored authoritatively • E.g. to restore deleted OU
