| + | Raid is not a backup. To protect the hypervisor configurations, | ||

| + | ===== 1. Multi-Tier Storage Strategy ===== | ||
| + | Veeam coordinates backups using the 3-2-1 principle: | ||
| + | * **Tier 1 (Production): | ||
| + | * **Tier 2 (Local Archive):** The Synology NAS Array (VLAN 10 interface). Veeam pushes compressed image-level backups of the VMs here nightly. | ||
| + | * **Tier 3 (Offline / Air-Gapped): | ||
| + | |||
| + | ===== 2. Virtual Machine Backup Jobs ===== | ||
| + | Deploy the Veeam Agent for Linux to VM-A and VM-B, and the Veeam Agent for Windows to the host machine. | ||
| + | |||
| + | Create an Image-Level Backup Job targeting your Linux VMs: | ||
| + | - **Mode:** Entire Computer (Volume Level). | ||

| + | |||
| + | Navigate to the **Guest Processing** tab of your Veeam Backup Job, enable Application-Aware Processing, and inject the scripts located in your [[reference: | ||

| + | * **Pre-Freeze Script (`veeam_pre_job.sh`): | ||
| + | * **Post-Thaw Script (`veeam_post_job.sh`): | ||
