ERROR_DATABASE_BACKUP_CORRUPT
The backed up cluster database is possibly corrupt.
ERROR_DATABASE_BACKUP_CORRUPT is Win32 error 5087 (0x13DF) and belongs to Failover clustering cluster database backup integrity.
Troubleshooting steps
- Record backup path, size, hash, and timestamp.
- Record cluster version and nodes that produced it.
- Record restore or validation diagnostics.
- Record storage health and interrupted-copy events.
What to verify
Verify whether the backup of the cluster configuration database appears corrupt. Check backup path, size, hash, and timestamp together with cluster version and nodes that produced it.
Handling, retry, and recovery
Do not restore the suspect backup; obtain a verified backup or recover configuration through supported cluster recovery procedures.
Practical example
A copied cluster backup is truncated during transfer.
