1. Prerequisites:

• A Proxmox VE cluster or standalone Proxmox server running.
• Veeam Backup & Replication 12.2 installed on a Windows server.
• Ensure Proxmox has the Veeam Agent for Linux installed if you’re doing an agent-based backup.

2. Backup Process:

A. Adding the Proxmox Host to Veeam:

1. Open the Veeam Backup & Replication console.
2. Go to “Inventory” > “Managed Servers.”
3. Right-click and select “Add Server.”
4. Choose “Linux,” as Proxmox is based on Debian.
5. Enter the IP address or hostname of the Proxmox server and provide the SSH credentials (root or a user with appropriate permissions).
6. Verify the connection, and Veeam will add Proxmox to its managed inventory.

B. Creating Backup Jobs:

1. Go to the “Home” tab and select “Backup Job.”
2. Choose “Virtual Machine” as the backup type.
3. Select the Proxmox VMs you want to back up.
4. Choose your backup repository (storage location for backups).
5. Configure the backup schedule, retention policies, and any advanced options like encryption or compression.
6. Save and start the backup job.

C. Monitoring Backups:

• You can monitor backup jobs in the “History” or “Home” tab to ensure backups run successfully.

3. Restore Process:

A. Full VM Restore:

1. In the Veeam console, go to the “Home” tab and select “Restore.”
2. Choose “Entire VM” and select the Proxmox VM from your backup repository.
3. Choose the restore point you want to use and follow the wizard to select the destination Proxmox server.
4. Confirm and start the restore process.

B. File-Level Restore:

1. Go to “Home” > “Restore” and select “Guest files (Linux).”
2. Choose the backup point and select the VM you want to restore files from.
3. Browse the file system and restore specific files or directories.

C. Instant Recovery:

1. Select “Instant Recovery” to start the VM directly from the backup storage.
2. This allows for minimal downtime while restoring the actual VM in the background.

Step 1: Prepare Proxmox Nodes

1. Update and Upgrade Proxmox VE on all nodes:

apt update && apt full-upgrade -y

2. Ensure that all nodes have the same version of Proxmox VE:

pveversion

Step 2: Set Up the Proxmox Cluster

1. Create a new cluster on the first node:
   • pvecm create my-cluster
2. Add the other nodes to the cluster:
   • pvecm add <IP_of_first_node>
3. Verify the cluster status:
   • pvecm status

Step 3: Install Ceph on Proxmox Nodes

1. Install Ceph packages on all nodes:

install ceph ceph-mgr -y

Step 4: Create the Ceph Cluster

1. Initialize the Ceph cluster on the first node:
   • pveceph init --network <cluster_network>
2. Create the manager daemon on the first node:
   • pveceph createmgr

Step 5: Add OSDs (Object Storage Daemons)

1. Prepare disks on each node for Ceph OSDs:
   • pveceph createosd /dev/sdX
2. Repeat the process for each node and disk.

Step 6: Create Ceph Pools

1. Create a Ceph pool for VM storage:
   • pveceph pool create mypool 128

Step 7: Configure Proxmox to Use Ceph Storage

1. Add the Ceph storage to Proxmox:
   • Navigate to Datacenter > Storage > Add > RBD.
   • Enter the required details like ID, Pool, and Monitor hosts.
   • Save the configuration.

Step 8: Enable HA (High Availability)

1. Configure HA on Proxmox:
   • Navigate to Datacenter > HA.
   • Add resources (VMs or containers) to the HA manager.
   • Configure the HA policy and set desired node priorities.

Step 9: Testing High Availability

1. Simulate node failure: Power off one of the nodes and observe how the VMs or containers are automatically migrated to other nodes.

Step 10: Monitoring and Maintenance

1. Use the Proxmox and Ceph dashboards to monitor the health of your cluster.
2. Regularly update all nodes to ensure stability and security.

Optional: Additional Ceph Configuration

1. Add Ceph Monitors for redundancy:bashKodu kopyalapveceph createmon
2. Add more Ceph MDS (Metadata Servers) if using CephFS:bashKodu kopyalapveceph createmds
3. Tune Ceph settings for performance and reliability based on your specific needs.

By following these steps, you will have a robust Proxmox VE and Ceph high availability setup, ensuring that your VMs and containers remain highly available even in the event of hardware failures.
