Prerequisites for Instant Restore on XCP-ng
Before performing an instant restore to recover XCP-ng VM, ensure you have the following:
- Ensure that you are using a reliable backup solution compatible with XCP-ng.
- A storage system that houses your VM backups (local, NFS, or cloud-based).
- Administrative privileges to access and manage the XCP-ng environment.
- The VM should be backed up with its complete configuration, including disk, memory, network, and other important settings.
How to Perform an instant restore to recover XCP-ng VM Step-by-Step
Step 1. Identify the Affected VM
- Navigate to the VM management interface.
- Identify the VM based on its UUID, name, or associated services.
- Confirm that a recent backup exists in the repository for the affected VM.
Step 2. Verify Backup Consistency
Before initiating the instant restore, check the integrity of the backup.
- Check Backup Logs: Use your backup software’s logs to verify that the backup completed successfully.
- Run a Test Restore: If possible, test a restore on a non-production VM to ensure data accuracy.
Step 3. Initiate the Instant Restore Process
Using Xen Orchestra or other backup software integrated with XCP-ng, follow these steps:
✍In Xen Orchestra
1. Open Xen Orchestra and navigate to the "Backup" menu. Locate the backup job associated with the VM.
2. Choose the repository where the backup is stored (e.g., NFS, SMB, or local storage).
3. Select the "Restore" option and enable the Instant Restore mode if available.
4. Instead of transferring the backup data to production storage, the VM is booted directly from the repository.
5. Keep an eye on the VM status to ensure it boots successfully.
Step 4. Configure VM Settings Post Restore
1. Network Configuration: Assign the correct virtual network interface and IP settings.
2. Disk Mapping: Ensure the virtual disks are correctly mapped.
3. Verify Services: Check that all critical services hosted on the VM are running as expected.
Step 5. Migrate VM to Production Storage
While the VM is running from the backup repository, initiate a background task to transfer it back to production storage.
1. In Xen Orchestra, use the “Migrate” feature to move the VM to its original or preferred storage.
2. Ensure the migration completes without errors to avoid performance issues.
