I am now using a spool to see what is happening for the locally attached Coraid storage. The locally attached storage runs at a (contended) write of 77MB/s and read of over 100MB/s as confirmed by the tool ddt. So I now have a Full backup running off local attached storage (Coraid, ext3) to fully local storage (HW RAID with BBU, xfs). However bconsole's "status client" still shows activity at around 20-30MB/s (Bytes/sec=24,363,733) with bacula-fd reading off the target at around 20-30MB/s to make a local 250GB file. Incidentally, bacula-sd periodically writes to tape at ~ 100MB/s. Google searches suggest that there might be a problem with the speed at which local spool files are made. 2006: http://www.mail-archive.com/bacula-users@lists.sourceforge.net/msg09171.html 2010: http://www.adsm.org/lists/html/Bacula-users/2010-06/msg00272.html Is there a problem with bacula-fd?
