What does HRESULT 0xC00D2735 (NS_E_DRM_UNABLE_TO_CREATE_BACKUP_OBJECT) mean?

NS_E_DRM_UNABLE_TO_CREATE_BACKUP_OBJECT

The exact DRM condition

0xC00D2735 maps to NS_E_DRM_UNABLE_TO_CREATE_BACKUP_OBJECT. Read it as a result from license backup, restore and anti-abuse state: the DRM runtime cannot create the backup/restore object required for this operation. Keeping the “unable to create backup object” boundary intact prevents a later playback message from hiding the original DRM failure.

Place in the DRM workflow

The workflow around this result matters: only licenses carrying the backup/restore right are eligible, and licenses with secure state can be intentionally excluded by the issuer. In addition, backup and restore are multi-stage asynchronous operations; one damaged member or a stale request identifier is not equivalent to an unavailable service.

A useful investigation order

1. Prove the boundary by ensuring you can record the factory/interface call, runtime and stub-library versions, outer object state and first inner HRESULT.
2. After you correct component/version or initialization state and create a fresh backup/restore object, verify both the requested right and the final store/device state.

State to capture before retry

• Code-specific proof: record the factory/interface call, runtime and stub-library versions, outer object state and first inner HRESULT.
• Protected identity: backup or restore operation ID.
• Operation state: backup directory contents and manifest consistency.
• Persistence or transport: per-license backup/restore eligibility.
• Security context: service response, reset count and daily restore limit.
• Correlation point: target machine identity and final license-store commit.

Targeted fix

Resolve the underlying condition directly: correct component/version or initialization state and create a fresh backup/restore object. A player reinstall, reboot or new license request is useful only when it changes the condition “unable to create backup object” and can be verified against the original evidence.

Representative case: The application reaches the backup/restore stage but object construction fails before any content or server work begins.

Nearby results with different meanings

Verification after correction

Repeat the operation that originally returned it. Assert the exact HRESULT at the producing API in the failing “unable to create backup object” fixture; then change only the relevant precondition and confirm that the corrected run completes without substituting a neighboring DRM result. After correcting it, verify the requested action and the final license-store, secure-clock, device or migration state relevant to “unable to create backup object”.

What the missing object would have owned

The backup/restore object normally owns license backup and restore operations and their status callbacks. Object creation fails before that responsibility can be transferred to a live interface, so later player or server messages are secondary.

For this object specifically, preserve the backup path, operation ID, eligible-license set and completion state. A successful fix should create a new backup/restore object and then complete its first real operation, not merely make the factory call return a different generic error.
