Backup failed

Hi,

I'm moving a Virtualmin GPL server to a Virtualmin Pro AMI. I assumed the best way to perform the migration would be to backup every domain and then restore them on the AMI. If that's not the best way, please let me know.

Anyway, when trying to perform a backup I receive the following error message.

Backup failed : Failed to open /home/scottalger/domains/princedimitri.eu/.backup/princedimitri.eu_mail for writing : Bad file descriptor
