Migration_Failed for some recoveries

If you’re encountering a “Migration_Failed” message, the most effective first step is to download and review the Veeam logs. You can download the logs from within the Cloud IBR Recovery Overview in the Recovery Network Information section. These logs will provide detailed error information to help determine the root cause.

These errors typically indicate that the backup data stored in object storage is either corrupted or being modified during the recovery process.

Troubleshooting Steps

1. Schedule your Cloud IBR Recovery during a window when there are no backups running, to ensure that Veeam backup jobs are not modifying the backup data in object storage during the recovery process. i.e.:

  • If your backup window is from 6PM to midnight, schedule the recovery to run after midnight.
  • If your organization runs hourly backups during the day, i.e. from 6AM to 6PM, you’ll need to run recovery tests outside of those hours or temporarily disable backups during the recovery window.

If the above step does not resolve the issue, perform the following steps:

2. Perform an Active Full Backup

  • Run an Active Full backup for the affected server.
  • Wait for it to complete successfully.
  • Attempt the recovery again, ensuring that no other backups are in progress during this time.
