### QA Verification Summary for **Create Instance from Backup** Feature
All major workflows, APIs, and edge cases have been verified successfully on
multiple environments (including cross-version restore and creation of an
instance from a backup).
### High-level Overview by Test Areas:
**Backup Creation / Create Instance from Backup**
- Tested backup creation via API (create backup) and UI.
- Verified full instance configuration captured in backup metadata.
- Verified scheduled and manual backup workflows through API.
- Confirmed usage tracking per backup offering.
- Fully tested create vmfrombackup API for:
- Standard scenarios.
- Create an instance from backup when the original instance is expunged.
- Configuration overrides (compute offering, disk offering, network, ssh
keys, etc.).
- Restore with preserve IP option.
- Restore of a single volume.
- Verified error handling for missing resources and broken metadata.
- Confirmed API responses include correct instance/backup references.
**Plugin Support**
- Verified Dummy, NAS (NFS, CIFS, CephFS), and Veeam plugin workflows via
API and UI.
- Tested NAS host dependencies and storage configurations.
- Verified Veeam plugin integration for backup/restore.
- Verified restore/create instance (on v4.21) from a backup created at v4.20
**UI Behavior**
- Checked metadata display, restore config prefill, and override options.
- Verified restore type selection and plugin visibility.
**Alerts & System Integrity**
- Tested alerts on storage thresholds and manual capacity configuration.
- Ensured backups and restored instances persist after expunge.
- Confirmed audit logging and system stability under normal load.
**Negative & Edge Cases**
- Blocked invalid API calls (e.g., missing offering, broken metadata,).
- Handled backup plugin unavailability and full storage gracefully.
- Verified no orphaned volumes remain after cleanup.
