Yes. You can mount the gluster on the host running bacula-sd, (where the USB3 drive is attached), and backup directly. > > Or alternatively, I am wondering maybe stream the data off gluster to > a "new' disk in the bacula server via nfs with rsync and then have > bacula back that "new" disk up to the external USB3 disk? Either way, the entire gluster, of necessity, must be read, so performance will be impacted. The pre-copy is not necessary. Bacula has built-in spooling to disk that can be enabled. The spooling essentially does the same stream-to-disk, but via Bacula's client-server socket i/o, rather than NFS. Whether or not spooling would be helpful is hard to say. It depends on many things, including network throughput, USB3 drive sequential write performance, etc. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
