Backups will not send emails, and only back up one server even though it is configured as it always has been to backup all servers, and send emails on success or failure. It did backup all servers when i click backup now, and it even knows it should send emails:
Starting background backup to /root/backup on SSH server mybackupserver.org ..
.. completion email will be sent to hostmaster@mydomain.org.
To be clear, the one server it backs up with an automated backup is transferred successfully to the remote server, however the file transferred has an unexpected EOF error when extracting, and is not usable as a restore from within virtualmin.
I can provide login information for a developer if you would like to examine my system configuration for possible issues that might cause this.
