Hello Alain, It does take more time but not too much more space on tape. Well, if you use compression that is. We have set compression on the backup's and they do not take that much more space. But be aware that compression does take some more time and CPU.
Our DR backup's created with VMIMAGE do contain the free space and that is what I want. I'd like the DR backup to be a perfect copy of the current situation. And also the CMS daily/weekly backup will dump a minidisk if it is not an CMS formatted volume. In that case the minidisk will be compressed and dumped. Formatted free space will compress very good but if the free space is not formatted then the old data will be dumped as if it was active data. But, as is already mentioned, if you do not want the free space to be dumped then you have to use the utilities for VSE itself. Regards, Berry.
