To resolve the Hyper-V backup failure issue, follow these steps:

1. Check for Windows updates and ensure that the host has recently been rebooted. This can help resolve any underlying issues related to the checkpoint and writer components.

2. Verify the status of the Providers and Writers by logging into the host and checking for any errors. Follow the steps in this article to check the Providers and Writers status: https://www.veritas.com/content/support/en_US/article.100020300.html If the writers are stable, proceed to the next step.

3. Enable the shadow copy attributes on the remote server where the backups are being performed. Set the shadow copy storage limit to "No Limit" to ensure sufficient space for the backups. Right click on the drive, Properties, Shadow Copies, settings, "No Limit".
