Backups fail with error:
STC failure occurred mid transfer.
No recent error reported from ShadowSnap agent.
Follow these steps to solve the problem:
- Check the Agent log by clicking the View Backup Logs link and then Show Agent Logs.
- If you see an error highlighted in red, search the most generic version of that error in the Knowledge Base.
2. Re-protect the agent from the web console. You can also repair agent communications from the Advanced Options tab per agent.
3. Upgrade to the latest version of the agent found at download.datto.com. Reboot the target machine.
If you are already on the latest version, uninstall all software, reboot, re-install, reboot, and try backing up again.
4. Make sure all three services are running and active:
- ShadowProtect Service
- StorageCraft Raw Agent
- StorageCraft Shadow Copy Provider
5. If the errors persist, force a differential merge from the Advanced Options tab of the Agents page.
6. Test a ShadowProtect backup against a NAS share on the Datto device to determine if ShadowProtect can back up successfully.
- Many of these transient errors were caused by earlier versions of ShadowSnap and ShadowProtect.
- Updating to the latest version of both is highly recommended.
- The latest installer package can always be found at www.shadowsnap.com. Be advised that a reboot of the target machine may be necessary.
