Some sites report that this setup works reasonably well, with the added benefit that VM can control the tape drives and libraries, bypassing Linux's rudimentary capabilities. And since the first backup the Tivoli Linux client makes is a complete, full backup, having the extremely high bandwidth VM internal networking capabilities is a big plus. Other TSM server can be used as well (AIX, z/OS, e.g.,), depending on which best suits your needs. Dave Jones Sine Nomine Associates Houston
