bk005: Error: Backup failed because backup image files have not been decrypted
Issue
When you try to start a backup for an encrypted system protected by a Datto SIRIS (virtual or physical) or a Datto ALTO XL appliance, you receive the error message, "Backup failed because backup image files have not been decrypted."
Environment
- Datto SIRIS
- Datto ALTO XL
- Datto Windows Agent
- Datto Linux Agent
- Datto Mac Agent
- Agentless Backups
Cause
To ensure the security of your data on encrypted agents, your Datto appliance does not cache your encryption key. As a result, when your device reboots, decrypted agents will automatically re-seal. This error is a result of an encrypted missing a backup because it was not unsealed by a device operator after a reboot of the Datto appliance.
Resolution
- Access the Datto appliance.
- Navigate to the Protect page. Sealed agents will display the notification shown in Figure 1.
- Select the Decrypt now box for the impacted agent, and enter its encryption passphrase when prompted.
- Attempt the backup again.
