Try setting "Maximum Network Buffer Size" to 32768 in both the storage daemon and client configs. It looks like something doesn't like the default 65536 buffer size. Also, a backup job can run a long time, and Bacula keeps the TCP connections open the entire time. Make sure a switch isn't timing out a TCP connection when it shouldn't. You may also want to look up the "Heartbeat Interval" setting in the Bacula docs. ... ------------------------------------------------------------------------------ Simplify data backup and recovery for your virtual environment with vRanger.
