I have a new installation of BE12 for Windows, with a Mac server running OS X 10.4 on a PPC. The agent installed fine, but when I run backup jobs it will crash and I'll get the "connection to remote system lost" error. If I reduce the size of the backup, then I can usually get through the full job. I've checked file permissions, backup settings, and anything else I could think of, and they're identical to any jobs I have setup that work successfully (I do have successful backups on a separate group of Windows and Mac servers). I'm backing up the files to a Lacie 2TB Ethernet RAID disk. Anyone else having this issue, or know how to fix it?
