Backup and Restore Group Policy Objects (GPOs)
GPOs can be deleted in two clicks; AD replicates the deletion to every DC, SYSVOL files vanish, and clients drop the policy at next refresh. AD Recycle Bin restores the container in AD but not the SYSVOL GPT files where the actual policy settings live - so per-GPO backup is its own discipline. Walks the full GPMC lifecycle: Back Up All... for a fleet snapshot, Back Up... for one GPO before a risky edit, Manage Backups... for preview-then-restore (View Settings opens an HTML report, Restore overwrites the live GPO), and the manual re-link step that the backup does NOT capture. Plus the PowerShell-only equivalent (Backup-GPO -All / Restore-GPO -Name) for scheduled / scripted use. Includes the four pitfalls (no description = uninformative Manage Backups list, backup-on-the-DC-fails-with-the-DC trap, untested-backup wishful thinking, View-Settings-first habit) and the link-map documentation gotcha.
