Use Cases and Application Scenarios
When to Use This Software
1. Unable to Restore from Backup (Backup File Corruption) You may encounter situations where standard RESTORE operations fail due to: – Corrupted .BAK files – Obsolete backup versions – Incomplete backup files – Media errors on backup storage
Stellar Backup Extractor addresses these scenarios by repairing the backup file structure and extracting the database.
2. Recovery Pending State (Transaction Log Corruption) Transaction log corruption can occur due to: – Abrupt system shutdown – I/O subsystem failures – Malware infections – Hardware failures
When DBCC CHECKDB with REPAIR_ALLOW_DATA_LOSS fails or would result in unacceptable data loss, this software provides an alternative recovery path.
