I initially suggested RAIT to the submitter, but he said he was not considering that -- if I remember right RAIT actually requires something like 5 tape drives. Maybe I am wrong on that though, because I looked at the code about 5 years ago. In any case, once you are talking about an LTO4 drive, it is currently impossible or nearly so to drive it full speed (except possibly by some high end IBM mainframes), so why complicate things when Bacula still lacks a lot of nice features ... :-) Kern ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Bacula-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/bacula-devel
