Hi, small fix. It seems that it is even around 5-6 seconds delay resulting in extra 20 minutes per tape. And worse, I'm afraid that the tape drive do not stop nor slowdown tape movement, which would mean over 10 % of the tape lost because of filemarks. Hope that I'm wrong. -- Rudolf Cejka <cejkar at fit.vutbr.cz> http://www.fit.vutbr.cz/~cejkar Brno University of Technology, Faculty of Information Technology Bozetechova 2, 612 66 Brno, Czech Republic ------------------------------------------------------------------------------ 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
