ACPHO backup doesn't start - gets stuck when calculating data dimensions
I have the latest version of ACPHO installed on a Windows 10 PC. Starting from a few days ago, I've been experiencing issues in doing a complete 1:1 backup. ACPHO is set to manually start a complete backup to an external Toshiba 1TB USB 3.0 HDD. However, when starting, it displays "Calculating data dimensions..” (not sure this is the right translation since I have the Italian version) and gets stuck at this point. Data transferring never starts. It all went well until about 7 days ago, no updates since then have been released, now I have this big issue.
I've tried scheduling a new-from-scratch backup changing from “entire OS” to “Main HD” (C:), but the issue is the same.
How do I proceed?

Hello Fabio!
I would also suggest checking if there is available space at the destination.
If there is, consider downloading the agent again from your account and repairing the installation. https://kb.acronis.com/content/60195
If the issue persists after repairing, please raise a ticket with our support because that would require an investigation: https://kb.acronis.com/content/8153

I've tried both repairing the installation and reinstalling ACPHO from scratch. The backup started to work after a fresh reinstall. Repairing/modifying didn't solve the issue. Thank you very much for your help!
