Overview
Domain expertise for Cloud Backup and Recovery. Covers vaults, backups, restore operations, policies, and cross-region replication.
Critical Warnings
| Trap | Why |
|---|---|
| Vault binds single resource type | Server vault != disk vault != file system vault |
| Restore needs instance stop | Most VM restore requires the target instance to be stopped first |
| Backup storage incurs charges | Retention policies affect storage costs |
