It seems you need to restart the backup server after you add new unix
hosts. I added some hosts at the start of the week and after that all the
backups started failing with
"The connection to the data backup has been lost"
This happened for both existing (and working unix agents) and the new ones
I defined.
It took a little while to figure this out. At first I thought it might be
firewall related but looking at the network traffic showed that wasn't the
case. The debug output of agent.be (see agent.be -help) wasn't all that
useful and seemed to indicate normal operation.
