LTO3 tapes have a native capacity of 400 GB. If you store data that is highly compressable more data fits on a tape. If you have already compressed data like zip files, only 400 GB will fit on a tape. http://en.wikipedia.org/wiki/Linear_Tape-Open Ralf ------------------------------------------------------------------------------ Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects _______________________________________________ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
