Just wanted to share a quick thing I learned the hard way: snapshots alone are not a backup strategy. I once migrated a whole VM cluster and assumed the storage snapshots + cold copy would be enough — until an app-level transaction log mismatch showed up during restore. Now I always do application-aware backups for databases and mail, keep a separate file-level backup for config files, and push a copy to a public cloud bucket (watch the egress costs!). For full machine migration, verify drivers and network settings in a pre-prod clone, and don’t skip a restore test — disaster recovery plans that haven’t been tested are just paperwork. Small, regular restores beat huge, rare miracles.
