Cause

On-premises deployment of Acronis Cyber Protect 15 and Acronis Cyber Backup 12.5 does not support backing up to Cloud Storage if two-factor authentication is enabled.

This feature is considered for implementation in future versions of the product.

Solution

There are two possible workarounds in this case:

1. Disable two-factor authentication in Cloud console
2. Consider switching to Cloud deployment where two-factor authentication is supported: see User Guide for more information about deployment types.

More information

Backup to other destinations is not affected by two-factor authentication.
