The other issue is RAID-10 and mhvtl: if you do disk backup, why go through the extra layer of mhvtl? And not use ZFS -- I just finished replacing 4TB drives w/ 8TB ones in our server, with no downtime. -- Dmitri Maziuk <dmaz...@bmrb.wisc.edu> _______________________________________________ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
