Hello, Note: btape does not spool -- it writes directly to the tape. When it is writing random data, you may find that your CPU is maxed out. The speeds you see are quite reasonable in my opinion. It is unusual that one will reach the theoretical maximum speed. I recommend that you stick with

Thanks, Dimitri. I am backing up shared data. I've done some testing with independent bacula-fd instances running at the same time with identical configuration on both nodes. Bacula-dir is configured to connect to the client at the floating IP address. It seems to work well. I have failed over the

Hello, I have a system where the Bacula File Daemon must run on a high-availability pair of servers. I have some services managed by Pacemaker, but I have not configured this yet for the Bacula services. If I configure bacula-fd identically and start it on both servers in the HA pair, will there
