To be clear: raw, uncompressed bytes (even if the compression was done by Bacula)? Also, as I say, I never saw more than about 400 GB on these tapes before and the datasets shouldn't have changed radically - are LTO-3 drives better at compression? ------------------------------------------------------------------------------ _______________________________________________ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
